Steve BlascoSteve Blasco
Marine Engineering Geophysicist
Geological Survey of Canada

Steve Blasco received his Honours Bachelor of Applied Science degree in Engineering Geophysics from Queen's University, Kingston, Ontario, in 1972. For the past 25 years he has been employed as a marine engineering geophysicist with the Geological Survey of Canada, at the Bedford Institute of Oceanography, Dartmouth, Nova Scotia.

Mr. Blasco's research focuses on marine environmental and engineering geology studies. Seafloor and lakebed geological investigations are related to offshore oil and gas exploration in the Canadian Arctic and environmental problems in the Arctic and Great Lakes. Mr. Blasco's research has taken him to the Canadian Arctic, the Russian Federation, the Caribbean, Bermuda, China, Japan, Norway, Great Lakes and even the North Pole.

Current research activities include seafloor scouring by ice keels, submarine permafrost, bottom sediment contamination, and the use of shipwrecks as scientific time markers. His studies primarily focus on unravelling the geological history of seafloor and lakebed sediments over the past 2 million years.

Paul HeinerthPaul Heinerth

Paul Heinerth started cave diving in 1971 and has since participated in numerous expeditions to further man’s knowledge of the underwater cave world. Sanctioned by the Explorer’s Club on several occasions, Paul has found and mapped numerous new caves in Florida, Quintana Roo (Mexico) and Belize. Many of these caves are over 300 feet deep. He has collected countless samples of rocks to albino eyeless life forms.

Paul became a cave diving instructor in 1980 and still teaches on a regular basis all levels of cave diving, rebreather diving, trimix diving and sidemount style. He has published several articles and written various chapters in cave diving books. He has operated cameras and video equipment from the ice caves ofAntarctica to the deep wrecks of South Africa. Paul’s longest dive was at Wakulla Spring, in Florida. There he went 300 feet deep for 5 hours of bottom time and travelled a distance of more than 12,000 feet. The decompression schedule was a grueling 15 hours long.

He is currently a member of the Weeki Wachee Karst Project, near Tampa Florida. So far Paul has reached 407 feet of depth exploring in Weeki Wachee and over 5,000 feet has been mapped. He looks forward to more...

Thomas IliffeTom Iliffe
Director, Marine Biospeleology Lab
Texas A&M University

Tom Iliffe is the director of the Marine Biospeleology Lab at Texas A&M University and has been conducting faunal and ecological investigations of marine caves for more than 30 years. Prior to starting at Texas A&M in 1989, Dr. Iliffe began his cave studies while a working as a research associate at the Bermuda Biological Station. He has conducted numerous scientific diving expeditions to observe caves around the Caribbean, Atlantic, Mediterranean, and Indo-Pacific regions. He has published 190 scientific papers and has discovered and described more than 250 new species of cave-adapted animals. He is also a diving and cave-diving instructor, using closed circuit rebreather and mixed gas diving technology to explore and investigate submarine caves around the world.

Brian KakukBrian Kakuk
Bahamas Caves Research Foundation

Brian is a former U.S. Navy Hard Hat Diver with 27 years of professional diving experience. His work has taken him beneath nuclear submarines and aircraft carriers, to jumping from helicopters into 10 foot seas, to record penetrations of underwater cave systems around the world.

Brian’s expertise in diving logistics and diving safety has been used widely in both the feature film industry and documentaries as a Diving Safety Officer, fixer, underwater double and stuntman and has experience in remote location logistics as well as studio, on-set work.

His research diving work as Diving Consultant for the National Museum of the Bahamas and various governmental and scientific institutions has revealed new species of cave adapted marine life and new species of extinct terrestrial animal fossils that are now repainting the picture of the Bahamas past environment.

With more than 3000 exploration cave dives, Brian is considered one of the leading authorities on the underwater/underground environments of the Bahamas and is a veteran of multiple high profile underwater cave expeditions in the Bahamas, Mexico, Dominican Republic, Belize, and the U.S. exit icon External Link exit icon External Link

Graham Maddocks

Graham Maddocks
Triangle Diving

For the last 5 years, Graham has been working with a number of local and international marine biologists to study the aggregation of the Bermudian Black Grouper. The Bermudian Black Grouper is endemic to Bermuda and appears to aggregate around the full moon to spawn. Graham's Company Triangle Diving has begun to develop techniques to view and record these fish without disturbing the spawning events. Furthermore Triangle Diving has supported Terrence Tysall and Tom Iliffe in their studies in Bermudas Cave Systems.

Robbie Smith

Robbie Smith
Bermuda Natural History Museum

Dr Robbie Smith is Bermudian marine scientist, currently the Curator of the Bermuda Natural History Museum and he is responsible for cataloging and identifying biological specimens collected on this expedition. Very few organisms have been collected from the deep fore-reef slope of the Bermuda Seamount historically. Deep mesotrophic reefs are a significant habitat for fishes in Bermuda but the ecology of these reefs is very poorly understood. A determination of the species diversity on these deep reefs and the relationships to shallower reefs is essential for future management and conservation efforts.

Dr. Smith was an Assistant Research Scientist at the Bermuda Institute for Ocean Sciences from 1991 to 2003 and a Lecturer in Biology at Georgia State University in Atlanta from 2003 to 2009. He has an extensive research diving background including NOAA saturation missions in the Hydrolab in St Croix and the Aquarius Reef Base in Key Largo. His recent research effort has been a NOAA-funded ten year study of the processes of coral recruitment and juvenile coral mortality in the Florida Keys National Marine Sanctuary to determine the effectiveness of Marine Protected Areas in enhancing coral populations. In Bermuda, he is currently collaborating in a study of the ecology of Bermuda’s outer reef terrace from 20-30m depth, documenting patterns of diversity with depth.
