Dr. Jason Krumholz
Follow the Artificial Reefs for Diving, Fishing, and Conservation: A Scientific Perspective
Richie Kohler’s diving experiences may have began in the waters surrounding his Brooklyn NY, roots, but for over thirty years his passion for diving and exploring shipwrecks has taken him to all corners of the globe.
He has explored and documented well-known shipwrecks such as the Andera Doria, RMS Titanic, and the HMHS Britannic, but it was the identification of the WWII German submarine, U-869, which catapulted his diving career into the world of television and underwater documentary filmmaking. That six-year effort has been the subject of several television documentaries and a best-selling book, Shadow Divers by Robert Kurson. The New York Times bestseller is soon to be a major motion picture by 20th Century Fox. Alongside diving partner John Chatterton, Kohler co-hosted 57 episodes of the History Channel series, Deep Sea Detectives, multiple documentary specials and continues to work on underwater projects for the film and television industry.
Currently residing with his wife Carrie Kohler in Sutton, MA, Kohler has two children, Richie III and Nikki. Currently, Kohler is conducting technical dive training, lecturing and leading expeditions to explore shipwrecks worldwide.

Exploring the Polar Regions: Above and Below the Water
Faith has spent most of her adult life in the ocean. Starting as a scientific diver and volunteering for public safety diving operations in the 1980’s, Faith became a technical diver and divemaster and has thousands of dives over her 41 year diving career. She worked with DUI to develop some of the first women’s drysuits while still a dive retailer in MA. She created the DUI DEMOTOUR, which promoted local diving while allowing divers to test dive DUI products, and the DIVEOPS program which promotes education about the risks of diving in contaminated water.
She has led expeditions around the world- many to the most remote places on Earth including multiple expeditions to both poles. Recently, she co-founded Blue Green Expeditions and now runs expeditions full time as she continues to share her passion for diving with divers from around the world. A frequent presenter at dive shows and conferences, she is a 2010 inductee into the Women Divers Hall of Fame and a member of the Boston Sea Rovers.
This year marks the 200th anniversary of the discovery of Antarctica. 200 years later, there are still so much waiting to be discovered in our polar regions. During this presentation, we will take you from the polar ice cap in the north to the frozen continent in the south- giving you a small taste of these unique environments and the ecosystems that depend on them.

Thoughtful Management of Decompression Stress
The Octavian Project
On July 4th 2018 the RV Explorer crew identified a recently discovered wreck. The Wreck of the D/S Octavian has been positively identified and confirmed through the recovery of the Engine & Boiler builders plaque. This was further confirmed by Jorgan Johannassan of the Maritime Museum on Oslo Norway. The wreck lies 70 miles from Cape May in 227’ of water. The Octavian was owned by Hjalmar Reksten Rederi of Bergen, Norway and was a 250’ Norwegian Freighter carrying Sulfur and Wood Resin.
Octavian left Galveston Texas on January 9, 1942 headed to St. John New Brunswick. The freighter never arrived in St. John and all 17 crewmembers perished without a trace. Due to an error, some history books have the Octavian located off Nova Scotia which is north of New Brunswick but there would be no reason for the ship to be in this location. It’s possible that St. John New Brunswick and St. John Newfoundland were confused and the coincidence of U-203 sinking an unknown vessel in the vicinity credited the 203 with the sinking.
Interestingly there are footnotes in multiple locations including, War Sailors.com, U-Boat War against the Americas and Researcher Edward R. Rumpf, that suggest that U-123 commanded by Hardegen sank the Octavian.
U-123 is also credited with sinking the Cyclops, Norness, Coimbra prior to the Octavian. U 123 then headed to Cape Hatteras to sink 4 more ships and damage a 5th .
The deck logs of the U-123 7th war patrol indicate that Hardegen sunk an unidentified freighter in the location of the now identified Octavian on January 17, 1942. The location given by Hardegen in his deck log is less than 700 yards from the ships current location. The ship sank in a plume of black smoke in less than a minute as Hardegen used his last stern torpedo. The U-123 then departed at maximum speed toward cape Hatteras.
This is exciting news and we hope to bring closure to the families of 16 Norwegian Sailors and 1 Canadian sailor.
Credit to this project and research should go to the RV Explorer team Rustin Cassway, Brian Sullivan, Michael Dudas and Tom Packer. Others who helped in this research effort were Gary Gentile, Hildrun Sommer (our assistant in Oslo and former Evie Dudas Employee) The Maritime Museum in Oslo Norway, Richie Kohler for providing the grid chart and explain how to use it, Bob Cope of Full Ahead Sport Fishing and Bob Duckenfield of Jim’s Bait and Tackle.

Dr. John Littlefield
Underwater Archaeology in Turkey
Check back for the video or email email@example.com
The first scientific excavation of an ancient shipwreck took place in the summer in 1960 at Cape Gelidonya, Turkey. For the last six decades, Turkey has been a hotbed of archaeological excavations, with three of the world’s oldest excavated shipwrecks coming from Turkish waters. A plethora of other important wrecks have also been excavated giving vital and novel information about the evolution of ship construction, maritime trade, and seafaring cultures of the Mediterranean region.
This talk highlights some of the work done in Turkish waters, with discussion of diving safety methods incorporated to allow work at depths not easily assessable by recreational divers.
Dr. Littlefield majored in Anthropology and Archaeology at College of Charleston before gaining both a Master’s degree and doctorate from Texas &AM University. He is AAUS trained, a PADI Dive Instructor, a DAN Europe instructor, and the Diving Safety Officer for the Institute of Nautical Archaeology, as well as a member of the Archaeological Diving Control Board of Texas A&M University.

The Curious World of Seaweed
The Curious World of Seaweed is Josie’s newly released book. Marine algae are the supreme eco-engineers of life: they oxygenate the oceans, create habitat for countless other organisms, and form the base of a food chain that keeps our planet unique in the universe as we know it. In this visually stunning presentation Josie Iselin explores both the artistic and the biological presence of some of the seaweeds and kelps that live in the thin region along our Pacific Coast and beyond. Historical botanical illustrations and Iselin’s signature portraits of each specimen reveal their vibrant colors—whether rosy, “olivaceous,” or grass-green—and whimsical shapes. Iselin posits that we can learn not only about the seaweeds but also from them: their resilience, their resourcefulness, their poetry and magic. Josie will describe her path as an artist into the science of seaweed and share a few seaweed stories, introducing a few women scientists who were crucial in broadening our understanding of the oceans. Projections of Josie’s spectacular imagery of seaweeds—collected from her constant wanderings along our California coastline and beaches—will help explain the science and impart the wonder of this ocean universe.

Bringing Tobago’s Coral Reefs Online: The Maritime Ocean Collection
The Maritime Ocean Collection integrates state-of-the-art 360º photography, Google Street View, smartphone technology, and videography, to allow anyone – adult or child, Trinbagonian or visitor – to view Trinidad and Tobago’s remarkable underwater world. We have built an underwater collection of Tobago’s coral reefs and marine environments to increase awareness, engagement and education, and to instill a sense of stewardship for these fragile marine ecosystems. This imagery will form the basis of Trinidad and Tobago’s first online coral-reef collection and will provide a baseline record for scientific comparison and management.
Anjani is a Marine Biologist with a special interest in coral reef ecology and understanding drivers of marine spatial patterns and the impacts on livelihoods. During her time at the University of Queensland, Australia, she mapped coral reefs around the world using 360-degree imagery technology for the purpose of online engagement and outreach as well as scientific research. Through the Maritime Ocean Collection Project, she aims to create novel opportunities to engage with people on critical coral reef issues by meshing state-of the art 360-degree photography and Google street view to strengthen the connection between people and coral reefs and to showcase their importance and how we impact them. Anjani also writes a weekly column for the Tobago Newsday collected in the blog, Wild Tobago.
Exploration and Ecology of Twilight Zone Fishes
Fifteen minutes. That’s all the time they have to collect their data at 500 feet. Dressed like “aquanauts,” they’re the first divers to ever visit these deep coral reefs. After documenting the habitat, conducting fish surveys, and collecting potential new species, they begin their ascent. It will take six hours of decompression before being able to surface. Diving to these depths took years of preparation for Ichthyology Graduate Student, Tyler Phelps. Each dive takes hours of preparation and extensive safety precautions to mitigate the risks in conducting their research. Take a “dive” with Tyler as he shares what it’s like to explore the Twilight Zone, and the latest discoveries their team has found from these remarkable communities.
When his parents took him for stroller walks along the Long Beach peninsula (in California), they had no idea someday he would be diving deep below the surface. Inspired by family trips to the aquarium and his elementary school teachers, he has dreamed of becoming a marine biologist since he was eight years old.
In high school, Tyler captained the Marine Decathlon team and volunteered at the Aquarium of the Pacific. After attending Soka University of America (Aliso Viejo, CA) for two years for Environmental Studies and a swimming scholarship, he transferred to the University of Hawaii at Hilo to earn his Bachelor of Science in Marine Science.
During Tyler’s college career, he has balanced his love for diving and love of science. This harmony inspired the formation of his training company, Balanced Divers, to offer private instruction as a NAUI Course Director, Technical Diving/Rebreather Instructor, and has won several awards serving on NAUI’s Training Committee. As an undergrad, he learned about the research his idols were conducting at the California Academy of Sciences and the new species they were finding in this “twilight zone” of coral reefs. Tyler realized this would be a perfect avenue for his research and spent the next six years advancing towards that goal.
Today, Tyler is earning his Master of Science from San Francisco State University while serving as their Assistant Diving Safety Officer. He is a Graduate Student in the Ichthyology Department at Cal Academy and serves as one of their On-Call Dive Officers. Tyler researches how fish assemblages change across depth gradients, mechanisms that drive community structure of fish communities, and understanding the role deep reef ecosystems could play in the conservation of threatened shallow coral reefs.

Dive Computers and Decompression
What is programmed into Dive Computers and how do they work? These are some of the questions addressed in this presentation. Starting some general concepts of decompression theory, this presentation looks at how those theories are translated into models which can be used to generate decompression tables and ultimately be programmed into Dive Computers. Since there are different models, this talk looks at the response to the same profile by various tables and computers. The advantages and disadvantages of dive computers will be examined, as well as factors that can influence susceptibility to decompression sickness which tables and computers do not incorporate, and activities divers can incorporate to reduce their risk for decompression sickness.
Karl Huggins has been the Director of the Catalina Hyperbaric Chamber Facility at the USC Wrigley Marine Science Center since 1992 and has been involved with the treatment of hundreds of divers during that time. He is noted for his work in decompression theory and models, which resulted in the Michigan Sea Grant (HUGI) tables and his participation in the development of the EDGE dive computer. Karl enjoys educating divers in the area of decompression (making divers more aware of the limitations of dive tables and computers) and diving safety. To that end he has given hundreds of lectures, seminars, and workshops as a featured speaker at conferences around the world. In 2011 he co-moderated the Validation of Dive Computers Workshop at the annual meeting of the European Underwater and Baromedical Society in Gdansk. Karl is the 1990 recipient of the Leonard Greenstone Diving Safety Award, the DAN/Rolex Diver of the Year for 1993, the 2004 Conrad Limbaugh Memorial Award for Scientific Diving Leadership and the 2008 California Scuba Service Award.
Diving Lake Champlain – From Recreational to Technical
Having grown up on Lake Champlain in Malletts Bay, it was only a matter of time before scuba diving became more than a hobby. First started diving in 1978, my wife Ellen and I built our first Dive/Research vessel (R/V Amazon) in 2011 for the purpose of located new places and structure to dive on. Since then, that vessel has been modified several times to provide improvements to safely dive on unknown sonar targets while ensuring minimal impact and damage to sensitive sites. To date we have logged over 3000 sonar targets which only a small fraction of have been identified. Our season typically runs from April to December in which we try to identify as many targets as possible while enjoying the beautiful scenery of the Champlain Valley. When the weather cooperates this usually means 50-100 dives and ROV surveillance when diving is not practical. Our hope is that someday we can help establish a unified database of targets so those interested can assist in their identification to add to the well preserved underwater Museum of Lake Champlain.
Rebreathers: For Tech…but also photographers, recreational divers,…and you?!
Rebreathers have traditionally been considered equipment for technical divers. The reality is that rebreathers provide significant advantages for the advanced recreational diver as well. We will look at types of rebreathers, how they function, training programs, and how the average recreational diver can enjoy their diving more with this fascinating technology.
Jeff is the President of Next Generation Services, where he provides consulting and training services in the diving market. Clients include rebreather manufacturers, training agencies, and legal agencies. Jeff has participated or lead over 70 diving expeditions during the past 30 years, to places like Palau, Canary Islands, and Antarctica.
