September 9, 2011 - What Lionfish?


To all those who are new to my blog, to get the gist of it please read, "Welcome Aboard" from the May 1, 2011 posting and peruse a few of my other Dive Blog Reports from weeks past. See side bar to the right for a list of reports.

Olympus Dive Center in Morehead City, NC.

     Captain Robert Purifoy, the proprietor of Olympus Dive Center, had to make a tough decision over Labor Day weekend regarding wether or not to run charters on this busy last weekend of summer. On Friday, before the weekend kicked in, on September 2nd Robert ran a charter on the M/V Olympus less than one week after Hurricane 'Irene' tore through the region creating 25 foot seas over our beloved wreck sites. Needless to say the turbidity that such swells creates tends to ruin visibility on the wrecks for many days afterwards. The Olympus made way out to the wreck of the W.E. Hutton aka Papoose.  At 32 nautical miles due south of Beaufort Inlet, NC, the Papoose is the furthest from offshore we will venture on a regular days charter.  Captain Robert had hoped to find the best visibility available by running as far out as he could. Another possible advantage the Papoose offers is 30 feet of relief from the sea bed. When silt is stirred up, as it begins to settle out it creates a layer lower to the sea bed with better viz the shallower you go. Despite the effort, it was discovered by the Olympus mate, Bud Daniels, that the visibility on the bottom was less than five feet with not much better conditions up shallower. The Olympus then headed over to the next best bet, the wreck of the USCG Cutter Spar to try there luck there. The Spar is about 8 miles closer to the beach but also has at least 30-35 feet of relief from the bottom. As luck would have it they encountered enough visibility, at around 5-10 feet and maybe a little better at the top of the super structure, to tie up to the Spar and conduct a dive. Word came over the radio that the wreck of the German U-boat, the U-352 had less than one foot of viz on the bottom and was not diveable at all. So the Olympus stayed on the Spar and made two dives with a mixed reaction from the passengers. Some made the best of it and had good dives while others were understandably disappointed but appreciative of the effort made by Capt Robert and were glad to just be diving. What can be said was that Captain Robert pulled out all the stops and did his best to get divers offshore to do what they came here to do and that was to dive. On a side note, Hurricane 'Irene' moved the Spar 200 feet from her previous location with a 45 degree list to port where before she once stood straight up. The force of the ocean is incredible. With the Spar in a new spot and laying differently it opens up some new photo ops for sure.

     As for the rest of the Labor Day weekend, it must have been a tough decision but, Captain Robert cancelled all the diving due to the low 'viz'. Trust me, it hurt us as much as it hurt you but customer satisfaction and safety are our primary concerns at Olympus Dive Center.  With this said, the 2011 dive season is not over. Hurricane 'Katia', which as of press time is forecasted to get pushed offshore and back to sea delivering some minor ground swell to the NC Coast. This coming weekend and beyond could be a go for both the Olympus and my boat the Midnight Express. Hurricanes and storms are nothing new to the Outer Banks and let me reassure you once the visibility clears up and the season gets going again you can expect some great dive conditions. So don't stash the dive gear away just yet. Give us a call, get the latest conditions and come out for a dive.



What Lion Fish?
     Once again, the Midnight Express has been stuck at the dock since the last Dive Blog Report due to open bookings and weather trouble so I have nothing new to report. This has given me the time this week to write about a topic that many of my passengers inquire about with frequency over the years. "Have you seen any Lionfish?", I get asked regularly. "What Lionfish?" I say jokingly. Since there discovery in 2000 off the coast of North Carolina, Lionfish have caused quite a stir with divers, the media and scientists. 
North Carolina Lionfish or Pterois.

W.E. Hutton, aka Papoose.

     Lionfish or the latin name Pterois is classified in to fifteen different species with only two of them located on the Eastern Seaboard of the United States and the Caribbean. Previous to there discovery in the North Atlantic they were indigenous only to the Indo-Pacific Oceans. Lionfish are known for there long sharp spines that happen to pack a poisonous wallop if a clumsy handler or fish gets stung by one. I have never heard of any major injuries from those who had gotten stung but I had heard it can really ruin your day. No one knows how Lionfish came to be off the East Coast of the US and eventually all throughout the Caribbean. Some theorize they were released by aquarium enthusiasts in Florida and then hitched a ride on the Gulf Stream currents all the way up as far away as Rhode Island. Juveniles are often spotted there as well as Long Island, NY during the warm summer months. The other theory is they were stowaways in cargo ships ballast tanks. Ballast tanks carry sea water in place of cargo when empty so there hulls will ride deeper hence giving them better stability. The ballast water is flushed out when they prepare to take on cargo allowing whatever is in the water to be released.  If a Lionfish was carrying eggs, 'Voila' Lionfish Invasion! This article however is not a debate as to how they arrived or who saw them first. I'm merely reporting stories I have gathered from people who were there when they were first sighted and passing on my own observations.

     As for me, the first time I ever heard of a Lionfish being spotted off the east coast of North Carolina was in the summer of 2001 while working as a mate for Capt Robert on the vessel I captain today, the Midnight Express. I heard some talk on the VHF radio about Lionfish sightings on some of the wrecks but didn't pay much mind to the chatter. Eventually, I saw Lionfish on the wrecks with my own two eyes during that first season and, of course, I started to believe the rumors. As the years rolled on I began to see newspaper and television stories on the subject and continued to speak to divers over seas and at home who would talk of the Lionfish invasion. "Hey did you hear about Lionfish in the Atlantic" divers would say to me during small talk. I would brag of course, "I was there when they were first spotted". You see, anytime an invasive species is found in the world it causes a lot of understandable stress. Rabbits were introduced to Australia in the late 19th century and nearly wiped out farmers crops. Zebra muscles indigenous to eastern European waterways were introduced to the Great Lakes in the US about 25-30 years ago creating terrible damage to the fishing industry and to any structure that had plumbing or pumping systems by fouling up the intake pumps. So when Lionfish were discovered in the North Atlantic scientists started to take notice. "what kind of trouble could they cause?", was asked. Potentially they could do a lot of damage to commercial fishing since Lionfish have a gluttonous appetite and love to eat just about anything including juvenile Grouper, Snapper and many other commercially valuable fish species.

     The first documented sighting of a Lionfish was on the wreck of the Naeco some 36 nautical miles south of Beaufort Inlet, NC by Darryl and Trish Boyer while diving from the dive charter vessel Atlantis IV. They even managed to take a photo of the specimen and later have it confirmed by an aquarist at the Pine Knoll Shores Aquarium. It had been reported that Lionfish had been spotted in Florida prior to this sighting but I have yet to find any research on this. I had heard another story from Captain Robert himself that in 1999, a year prior to the Boyers sighting, that he had seen one on the wreck of the W.E. Hutton aka Papoose while searching for sharks teeth. He said to himself "Sometimes you see the darndest things" when he saw the Lionfish swim by. Unfortunately for him he did not take any photos or video nor did he even report the sighting to anyone in particular so it was never officially documented.
     Sometime in August or September of 2001, avid diver and fish collector, John Wisniewski went on a mission to recover the first known live specimen for scientists at the National Oceanic and Atmospheric Administration (NOAA) for them to study. I was present on board the dive vessel Olympus captained by the late George Purifoy when John went in on the wreck of the Papoose to recover a Lionfish. He returned after his first dive with a live specimen and handed it over to scientist, Paula Whitfield of NOAA later that day and actually got paid a bounty for the fish. Paula to this day is one of the leading authorities on North Atlantic Lionfish. At this time NOAA's heads were perked up and they wanted to know which species it was and how the heck did it get there and with a live specimen they could certainly learn a lot more. I remember staring at this rather small fish in the cooler wondering "where did you come from anyway?" I had seen Lionfish before on many occasions while living and working in Mozambique, Africa in the year 2000. They were common on most reef dives. The first time you see a fish like this you are intrigued to say the least. The 500th time you see one the intrigue starts to wane.

    After these early sightings in 2001, every year there after more and more documented sightings had been made off North Carolina on more wrecks sights over a wider area. With this increase in population over several years it became apparent that Lionfish were really enjoying their new digs off the Outer Banks of NC and were thriving unmolested. It was also determined that Lionfish have no known predator combined with abundant food sources allowing them unlimited growth. "What to do about the Lionfish problem?", became the big question amongst scientists, commercial fisherman and anyone who stood a chance to be harmed by this invasion. 
    During these early years the Lionfish epidemic spread like wild fire throughout the Caribbean and is still going strong today and is taking a serious toll on the indigenous marine life threatening to wipe out fishing and recreational diving industries wherever they proliferate. Reefs in the Caribbean pretty soon were reporting to be inundated with Lionfish but lacking many other fish species. To combat this outbreak dive operators and scientists began trying different approaches to the problem. One of which was conducting Lionfish pole spearing campaigns through organizations such as, I Spear Lionfish where tourists armed with a basic pole spear were allowed to spear Lionfish during their recreational dives. I have heard reports of dozens of Lionfish being pulled off of small reef systems in a single day. Similar efforts are being made throughout the US where pole spearing of Lionfish is encouraged by dive operators. Lionfish Rodeos or Roundups are conducted where competitions are set up as to who can spear the most Lionfish. Divers are able to participate in an activity that is harmless to indigenous species and are having a good time doing it. In addition, restaurant chefs are being prompted to add Lionfish on the their menus.  (See this Link.) Apparently, Lionfish is a very good eating fish and tastes much like Black Sea Bass. No kidding! One such Facebook page called, Eat the Lionfish is dedicated to such a mission. If you look on there page it says, "They are dedicated to the mass slaughter and cooking of Lionfish on the East Coast". Their mission statement doesn't get any simpler and angrier than that. There are many other organizations like this from the Caribbean to North Carolina. Creating a consumer demand for Lionfish is an effective way to control and even decimate the species. Unfortunately, humans have done a good job of this worldwide to many other indigenous fish species such as North Atlantic Cod so why wouldn't it work for Lionfish?. I personally believe all these efforts to stem the Lionfish invasion are worth while and if you can even create an industry around the slaughter and consumption of a invasive species then lets go for it. At this point there is no way to completely remove Lionfish from the Caribbean and Atlantic Oceans. They are here to stay. At least methods are being established to control their growth and protect our natural fish stocks and reef systems.
     In 2009, after I returned from overseas to Olympus Dive Center to captain the Midnight Express, I was hired to take a group of NOAA scientists out to conduct research on them. NOAA had been doing studies steadily since 2001 but this was the first time I worked with them. I was instructed to pilot the boat to a set of waypoints that were small isolated reef systems only around 24 miles from the beach. The first few charters it seemed as though they were merely fish counting and locating ideal sights. After a few more charters they began going in and pole spearing as many Lionfish as they could from only half of the selected reefs and leaving the others untouched. I suppose the goal was to see how long it would take for them to repopulate these reefs while several other reefs were left unspoiled as a control subject. Once the season was over I never really found out what they discovered from this study but I do know that the winter water temperatures as far offshore as 30 miles dropped nearly to 50 degrees C hence killing off nearly every Lionfish within a 30 mile radius from land including, all of the Lionfish on the test reef sights NOAA spent a pile of money on the year before. Lionfish after all are a tropical fish species and will die off in cold water. During the course of the 2010 season very few if any Lionfish were reported seen within this distance. Once you reached approximately 36 miles from shore a diver could spot plenty of Lionfish though on the ledges and wrecks. I had heard NOAA was utilizing other dive boats in 2010 and traveling further offshore to locate and continue to study them. The following year brought yet another harsh winter for the Carolina Coast and once this years 2011 dive season commenced very few Lionfish had been spotted again within this 30 mile distance. As the season went on however more and more sightings were made and plenty were to be found on the offshore dive sights and even on those closer in. Lionfish are still there and if the next few winters are mild ones divers will be sure to see many more of them off the Outer Banks. 
    From my own experience, which is not a scientific one, I have not seen any difference to the fish populations on the wreck sights of North Carolina within the 34 miles radius of land. I continue to see large schools of Grouper and various species of Snapper, Black Sea Bass and Flounder on the wrecks and reefs. Earlier in the year in May we dived a wreck off the Wilmington Coast of NC which is about 55 miles south west of Morehead City on a wreck that is about 25 miles from shore. When I went in to explore the wreck I immediately noticed two things. I saw the largest size and quantity of Lionfish I had ever seen anywhere. I stopped counting basketball sized fish after two dozen and there were a lot more. The second thing I saw was the largest size and quantity of Black Sea Bass I had ever seen on a wreck as well as a healthy population of Snapper. I have no doubt, based on what I have heard, that the Lionfish invasion in the lower latitudes are having a much worse effect on indigenous fish populations but I'm not seeing that where I dive. Like I said though, I'm not a scientist or researcher. I am just making simple observations while diving.
    Whatever the future brings for the Lionfish is anyone's guess but when you leave Mother Nature alone long enough she works things out on her own terms. Humans can try to help and speed the heeling process up but many times we just make matters worse. Maybe we can focus our efforts effectively and make a positive difference in controlling these spiny maned pests and prevent these mistakes from happening again in the future or maybe its just wishful thinking. Time will tell that's for sure.


    I'm away from North Carolina right now on family business but the M/V Olympus will be running steady charters for the month of September. The Midnight express will be ready for action come next week starting on the 16th or maybe earlier with numerous charters scheduled until the end of the month. I hope to see you for some great Fall diving.


Happy Diving!

Photo Tip of the Week

    Having exceptional dive skills is essential to taking quality underwater photos. So, "What defines exceptional dive skills?", you might ask. The newest of the new divers should be primarily concerned with self preservation and minimize doing any task other than the basic ones required to perform a safe dive such as monitoring gas consumption, bottom times, ascent/decent rates, buoyancy control and navigation to name a few. Once you become more comfortable with your abilities and your surroundings then take up an addition underwater hobby such as photography. By all means if you are not sure if your ready then you probably aren't. Hold off and log a few more dives and sign up for additional dive training before grabbing a camera. I guarantee you that until you have the basic skill set down you will not be able to take even a simple snap shot with your camera. Photography requires a high level of concentration in order to do efficiently and if your focus is solely on your diving you will not be able to take pictures that are worthy of even showing a friend or posting on Facebook. In turn, if you are too focused on your camera and not your diving you are at greater risk of having an accident. That's common sense.  Once you begin to perform certain dive skills as though it were second nature you will be capable of paying more attention to your photography and turn out some really nice shots.
     The most important skill to master in order to become a better photographer is your buoyancy skills. Your ability to hover effortlessly over a subject without constant changes to your BCD is imperative. The alternative is to stand or kneel on the bottom and risk silting out your photos and even worse damaging fragile marine life. Too often I witness underwater photographers with terrible buoyancy skills with a very large expensive housed SLR set ups. They expend great amounts of energy merely swimming or trying to position themselves with their camera to get their shot. More times than I would like to report I would have to intercede to prevent a beautiful sea fan or hard coral fall victim to a careless fin kick. 
     Quite often photographers (like many divers) are grossly over weighted making it very hard to achieve neutral buoyancy due to the constant additions and subtractions of air to their BCD's. It doesn't help matters that this extra weight will cause a diver to swim with their feet down and head up while the natural position should be horizontal. It should be any divers goal, especially underwater photographers, to find what their absolute minimum amount of dive weight is required for them to obtain neutral buoyancy.  The skill for this is right in the open water course of any dive training agency but so few fail to heed it and too many instructors do not take the time to get the weight off their students before sending them out to dive on there own. The trick is to be relaxed when you jump in the water and exhale and not hold your breath while you are draining air from your BCD to descend. Once you are neutrally buoyant practice using your lungs for finite adjustments rather than adding or subtracting air. Once your tank runs down to under 500 psi at the end of a dive you should be able to float effortlessly at 15 feet with no air in the BCD. As for myself, when I dive with a 5mm wetsuit and an aluminum 80cft tank and my camera I require about 2-3 pounds of lead. With a 3mm suit I use zero lead. Most divers with high levels of experience can brag about the same skill. Remember, the less weight the better! I can't stress this more.
    When I started to shoot video and photo underwater in 2003 I already had over 1500 dives to my credit. It is in my belief that this was one of my biggest assets that got me on my way to producing quality images in such a short period of time. My ability to remain motionless and hover over and/or in front of my subject and focus on my photography without jeopardizing my safety, was crucial. The only way to build strong dive skills is to dive and dive as often as you can while taking as many training classes available. I'm not saying everyone should have 1500 dives logged before taking a camera in the water. I'm merely saying that you should be a proficient diver before doing so. The time and amount of dives required to become proficient will vary from diver to diver. Some of the courses I recommend to take are Peak Performance Buoyancy and even freediving or breath hold diving courses. If freediving doesn't build your comfort levels and reduce your fears in the water than nothing will. Personally my favorite courses were the technical courses such as Advanced Nitrox, Decompression Procedures and Trimix Diver. Even if you don't intend to do deep/tech diving the skills you will learn in these courses will hone your dive abilities like no others.
   In closing, don't ever take your dive skills for granted and think there is nothing new you could learn to become a better diver and photographer. Absorb knowledge like a sponge, become comfortable in your water environment and then go take some awesome photos.

August 29, 2011 - U352 "From Hunter to Hunted"




The U-352: "From Hunter to Hunted"
by Mike Gerken
The U-352 with her crew at port.

The U-352 as she is today.
          As the predator, Kapitanleutnant Hellmut Rathke, of the German submarine U352 peered through the periscope at his unsuspecting prey, his desire for glory and his overwhelming sense of duty to the Fatherland must have clouded his better judgment as he planned to make his first war time kill on a heavily armed enemy ship in broad daylight.  On this day, May 9th of 1942, approximately 28 nautical miles due south of Morehead City, North Carolina, the crew of the United States Coast Guard Cutter Icarus would prevail in battle and be responsible for creating one of the most compelling WWII shipwrecks on the eastern seaboard of the United States.

            The U-352 and her crew of 46 men had only just arrived on the American coastline a few days prior without a single kill to their credit in the war.  The month previous had proven to be a highly successful time for U-Boat commanders operating off the Outer Banks of North Carolina during the war in what was dubbed as 'torpedo alley', due to the considerable losses of allied ships there at the hands of the German U-Boats.  By the time Rathke and the U-352 arrived, allied defenses of shipping had been stepped up considerably and successes for the U-Boats were scarcer and operations considerably more dangerous.  Regardless of the hazards, it seemed apparent that Rathke was highly determined to make a kill.

          The first signs that the cutter Icarus was being observed by the U-352 came in the form of sonar contact only 100 yards away.  Several minutes later a torpedo exploded in the sand some 200 yards off the port quarter of the Icarus leaving a plume of bubbles and sand from the sea bed marking the spot.  Rathke had taken his shot and dreadfully missed his target while tragically giving away his location at the same time.  The hunter now became the hunted.  It should be noted that the U-352 was operating in water of depths of only an astonishing 110 feet, which some experts would consider is suicidal considering diving deep as a means of escape was out of the question in this shallow of water.  In the next 45 minutes, Rathke would do all he could to avoid the barrage of depth chargers being thrown at him from the deck of the Icarus, but to no avail.  After sustaining terrible damage to his ship, with one crew member already dead, Rathke decided to surface his ship and evacuate the crew.  As soon as the U-352 surfaced, the crew began to pour out of the conning tower with the intent of abandoning the sinking ship.

Port with survivors of the U-352. (NARA)
The crew of the Icarus had mistaken their hurried exit from the ship for attempting to man the deck guns and began firing upon the stricken U-Boat and her crew.  The U-352 received relentless fire the Icarus until the true intentions of the submariners became apparent and the commanding officer ordered a cease fire. Thirteen of the crew of the U-352 would not survive this attack with many of them never making out of the sinking sub.  The men that managed to escape were all equipped with life jackets and drifted in the current for up to 45 minutes while waiting for rescue from the Icarus.  The 33 survivors including Kapitantleutnant Rathke were all taken immediately to Charleston, South Carolina where they would spend the remainder of the war as prisoners.  Considering that nearly 80 percent of the sailors serving in the U-Boat corp during WWII were killed in action, these men were fortunate to have survived.

Dive Vessel, Midnight Express.


       Today, I pilot the dive vessel, Midnight Express with a heading of due south from Beaufort Inlet making 17 knots right in to a 2-3 foot ocean swell. The bow pitches upward and gently drops down in to the trough of the next wave splashing water over the deck before repeating the process over and over again.  The eighteen passengers on board find a comfortable spot to hold on and enjoy the ride out to the final resting place of the U-352.  It's been more than 69 years after her sinking and 35 years after her rediscovery where divers still continue to come from all over the world to dive this enigmatic WWII ship.  There are very few German U-Boats in the world that are as readily accessible to sport divers as the U-352 is.  She sits in a mere 110' of seawater and is only a short 90 minute ride out from Morehead City via Beaufort Inlet.  Water temperatures climb in to the lower 80's F in the peak summer season making for a very comfortable dive experience.  Anyone holding a recreational SCUBA diving certification card with proper experience may dive the U-352 if they wish.

            As I approach to within 1000 yards of my coordinates, I slow down while my crew prepare to secure the vessel to the sub below.  Equipped with dive gear and a full face mask with a surface communication device, the mate stands fast along the port rail as I motor over the wreck.  The U-352 is being hunted once again, but with different intentions this time.  As soon as I see a clear sign of the sub on my depth sounder and my GPS indicates we are within 10 feet of my desired location, I signal for the mate to jump in with anchor in hand.  With a clank of the anchor chain and a splash he disappears from sight in to the 78F degree water.  As he makes his descent to the bottom, my other mate handles the anchor line while I maneuver the boat.  After less than a minute, my diver radios up to me and says "OK, OK, OK" indicating he has successfully tied us off to the desired location on the port side drive shaft on the stern of the sub.  Once the slack has been taken up and the line tied off, I call back down to my diver and say "OK, how does it look".  Today he replies, "all is ok, we have about 60 feet of visibility and a very light current heading from stern to bow".  "Excellent" I say to myself, "These are great conditions for my divers". 
More than 30 images were spliced together manually to create this composite photo of the
U-352. Photo taken in September 2010. 
I quickly head to the aft deck of the Midnight to give the good news in a form of a dive briefing.  I show them a composite photograph taken by myself that's made up of thirty separate images of the U-352 that when assembled displays the entire sub as she rests today.  Using this image I point out the highlights of the dive and go over the specifics in that she sits in 110' of water with a strong list to her starboard side. There are hatchways fore and aft on the hull that are open and accessible. Once inside a diver would need to navigate through a very small area with excessive amounts of silt.  As you swim through the sub you may be able to see well enough in front of you with a torch until you turn around to discover your fins have just kicked up the silt obscuring the visibility and your escape route.  I make it clear that only divers with special training and skills should attempt to enter the U-352.  Most everyone who comes to dive with me heeds my advice and is content on having a swim around the ship and maybe poking there heads in to the hatches for a look within.  After the short briefing, I ask if there are any questions.  Most at this point are anxious to get wet and abstain from saying anything that would delay their entry.   Within minutes all of my 18 divers vanish from site under the blue water and head down the anchor line to the historical shipwreck below.  Having dived the 'sub' myself at least 100 times, I can easily envision what the divers are encountering.

conning tower in the back. (new)
            Diving off the Outer Banks from June thru October means you will be diving in the warm clear waters of the Gulf Stream that surge up from the tropical Atlantic ocean.  As you hand over hand it down the anchor line the stern of the U-352 quickly comes in to view.  Dropping down to the sand and gazing upon this WWII artifact for the first time often gives one pause for thought.  A diver can easily identify the rudders, drive shafts that make up the running gear of the vessel.  If you look closely underneath the stern you will see the starboard propeller visible but half buried in the sand while the port propeller had been removed and salvaged in the 1970's.  Hovering over the top of the sub and swimming at a slow pace, you will come across the exhaust pipes where the diesel fumes would have been vented while the submarine operated surfaced.  While submerged a large bank of batteries would have propelled the ship at approximately 3 knots.  Past here the open hatches leading to within the aft section of the ship come in to view.  With a strong torch one can peer inside the blackness of the inner hull for a look inside the sub.  The sheer size of the tiny spaces these men had to live and fight in for weeks at a time is a wonderment.  After continuing forward for another few feet, the conning tower can be seen with a list to starboard that is reminiscent of the Leaning Tower of Pisa in Italy.  Upon closer inspection a very small hatch at the top of the conning tower leads in to the command room.  The hatchway is so small it would be impossible for a diver donning full SCUBA gear to access the sub from this point.  One can only imagine the chaotic scene 69 years ago as the crew of the U-352, many of them barely twenty years of age, frantically evacuated the sub one at a time from this hatch as exploding shells erupted and machine gun fire from the Icarus riddled them and the sinking ship.  Upon further contemplation, the reality of war in the form of the remains of the men that never made it out, comes to mind for some.  Indeed the U-352 is deemed a war grave by the German government and they desire for it to be treated with such respect.

            Once the conning tower has been reached and examined, a diver, if having sufficient bottom time and air supply remaining, may opt to continue on another 80 feet or so to explore the bow of the wreck.  The first thing to be seen on the swim down would be the gun mount for the forward cannon that once adorned the ship.  The gun itself was likely blown from its mount during the sinking and now lies somewhere buried in the near vicinity by decades of ocean sand and still awaiting to be discovered.  Passed the gun mount, there is another open hatchway leading to within and then yet another hatch only a few feet away. This one is on a 45 degree angle and would have been used to load torpedoes in to the forward torpedo room.  After analyzing the requirements needed to gain access within, most divers use prudent decision making and continue on with the tour from the outside.  Finally, after about a 200 foot swim from the stern, the tip of the bow and the torpedo tubes can be examined lying in the sand.  If the weapons that were fired from here had met their mark you would be reading a different story today.  One about how the Coast Guard Cutter Icarus and her crew had met her fate at the hands of a German U-Boat in 1942.

            Besides the historical significance, the U-352 has as a wreck dive the marine life that inhabits her today is yet another draw.  Amberjacks in their hunt for a meal chase schools of baitfish in to dense billowing balls around the conning tower.  This swirling action of the baitfish is mesmerizing to watch and on occasions the visibility is considerably hindered by the sheer magnitude of fish covering the submarine.  Other interesting marine sightings such as giant southern stingrays and loggerhead sea turtles as well as healthy grouper and snapper populations are but a few of the highlights.   Let me not forget to mention the intimidating and ever present fierce schools of barracuda that stand watch over the submarine in the currents above.  Once in a while we will even see sand tiger sharks on the U-352.  Sand tigers are a very common sight on the wrecks of North Carolina and a huge draw for sport divers to the region, but for reasons not understood they are not regularly seen on the sub.  For those who are lucky enough to see sharks swim along the hull of the U-352 is an added thrill.

            Most divers who make it to the far end of the wreck will need to consider turning around very soon to make it back to the anchor line to regrettably begin making their slow ascent to the surface.  As much as we all want to stay underwater longer, the laws of physics indicate otherwise.  We are merely visitors to the underwater world and modern day dive computers remind us of this repeatedly through the course of the dive with there flashing and beeping warnings.  Hand over hand divers one at a time make their way up the anchor line, do their required safety stops and begin clambering up the ladders of the Midnight Express.  As each one climbs on board I log them in and of course ask "how was your dive?"  For most I get a very enthusiastic answer.  Many divers at this point even indicate that they have wanted to dive this wreck for many years and were ecstatic at being able to scratch this off their list of 'must dives'.  "I finally got to touch the U-352" one man says with water dripping from his smiling face as he climbs the stairs.  With all back on board it 's time to make our way home while during the ride excited divers tell stories about there trip down to the U-352.  As often as I have dived this wreck I never get weary of her and I thrive off of helping others get a chance to see with their own eyes this underwater relic that is a reminder of a time in our history when the world was at war.



A Few Words First
Hurricane Irene.

         As Hurricane Irene approached Beaufort, NC as a category 3 storm with winds at better than 110mph I tried to find a reason to stay in my home with Annette for this event but could not find a single logical one. With the dive boats Midnight Express and Olympus pulled from the water and set on blocks at the local boat yard, I packed my computer hard drives in to a water proof case, propped our furniture up on chairs and headed to Raleigh to stay with friends. We kept track of the storm and the well being of friends from the internet and waited it out in comfort and safety. We even managed to take in a movie at the theatre and wander around a real shopping mall. Fortunately for everyone, Irene made landfall as a mere Cat 1 hurricane. I don't mean to downplay the storm or be disrespectful to those who lost or suffered during this but it could have been so much worse.  Annette and I returned on Sunday to find a few broken branches and the power off. Mind you Beaufort was in the eye of the storm as was Morehead City. My town home has a view of the intracoastal waterway and if you got on my roof you could see the ocean. We could find no signs of any major damage or flooding. As of last night the power came back on and life has begun to return to normal. Like I said a minute ago, we were lucky. If Irene came ashore as a Cat 3 with 130-140mph winds the outcome could have been much worse. With the Irene heading in to the history books and fading from the scene it is time to get back to business. Today, 29th Monday the Olympus will be placed back in to the water with the Midnight to follow today. Olympus has trips all this week while my boat will have to wait until Friday or Saturday before testing the waters out. Stay tuned for condition reports as soon as the first charter post 'Irene' is completed.

          Since the last Dive Blog Report the only diving that I have done has been in my bath tub. So for this weeks Dive Blog I will share with you a story I wrote on the U-352 for a Polish diving magazine, (apparently Poland's only dive magazine) Redakcja Magazynu Nurkowanie. The editor contacted the shop a few months ago looking for a story and accompanying photos of this famous WWII wreck and I thought it would be great writing practice to take them up on their offer. The magazine apparently is to be released this month but, unless you can read Polish, you might want to read the story below in English first. In case you are wondering, I didn't write the story in Polish. I wrote it in Mandarin and they translated it to Polish. I hope you enjoy this piece.
Keep your eyes out for a similar story to appear in SCUBA Diving Magazine in the Mar/Apr edition.


Happy Diving!

Photo Tip of the Week

The best camera and strobes with the perfect ambient light conditions and exposure settings will not yield a great shot by itself. The subject matter and how to compose it is extremely crucial in obtaining a great shot. Do your homework and research your dive site or wreck and have a plan before you enter the water. For example, I had a great idea for shooting the Sand Tiger Sharks inside the wreck of the Aeolus in North Carolina. From previous diving experience on this wreck, I was aware of a round hole in the roof of the super structure leading out to the blue water. I figured if I couldn't shoot a Shark I would shoot a human model posed beneath this round hatchway with Ambient light radiating down and from the sides.  A few weeks ago my mate had reported several Sand Tiger Sharks swimming about within this section of the wreck. Perfect. I had a model and I wouldn't have to pay it. Before I even got in to the water I had already composed my shot in my head. Now it was a matter of setting the right exposure and hoping the shark would swim where I wanted it to. As it would be, I was in luck. For thirty minutes I sat there composing different versions of the shot below and fired off maybe 75 to 100 photos before I managed to land one that I was very satisfied with (see below). With a little planning and observation I managed to compose, what I think, was a great shot. You can do this as well. Explore a wreck or reef, find a scene that appeals to your eye, compose the shot and try your luck. If the first time around doesn't work, go back and try again. I have so many great ideas for shots on the North Carolina wrecks that I am waiting to experiment with. It's a matter of waiting for the correct environmental conditions to arise or certain marine life behavior to do just what you want it to. No one ever said taking a stunning image is easy. If it were everyone would be doing it and then it would be less interesting.
This photo was not an accident. A lot of planning and
thought went in to getting this shot. Having a shark swim exactly
where I wanted it to may be contributed to a little bit
luck as well or maybe not.
