Sub: Nemo and Nomad (Triton 1000/2 models)

GlobalSubDive, USA

GlobalSubDive provides turnkey underwater exploration solutions with access to advanced technical diving teams in over 54 countries. Founded in 2014, GlobalSubDive completed three significant missions in 2016 to support global conservation efforts for Project Baseline. The first, with Miami Waterkeepers, increases the understanding and awareness of coral reef conditions near Port Everglades in advance of a dredging to expand the port. SCUBA divers collected valuable baseline data from 3 km of the Florida Reef Tract surrounding the Port Everglades shipping channel. Renowned explorer and environmental advocate Philippe Cousteau was part of the project and brought international attention to the initiative.

The second expedition teamed with Nekton and a group of leading scientists to execute the first mission of the XL Catlin Deep Ocean Survey in Bermuda. Two submersibles and 10 technical divers explored and documented five sites at depths between 15 and 300 m with nearly 100 dives conducted in 24 days. The team produced 138 baseline video transects and identified nearly 300 species of coral, sponge, and algae. Along with the participation of scientists, journalists, and media personalities, a UNESCO representative announced the world's first High Seas World Heritage Site, the Sargasso Sea, from inside the MUV.

For GlobalSubDive's third expedition, they partnered with NOAA's National Marine Sanctuaries and Office of Exploration and Research and BOEM to conduct laser and photogrammetry surveys of wrecks that sank in battle off of North Carolina in WWI. Submersibles explored the U-576 and Bluefields both at ~240 m depth while technical divers explored the wreck of the YP-389 at 90 m. The work advances NOAA's goal of expanding the Monitor National Marine Sanctuary and fosters ongoing collaborations between NOAA and Project Baseline.
