exploring the grand canyon of the ocean

A RARE OPPORTUNITY TO dive deep into one of the world's largest subsea canyons ABOARD A PRIVATE SUBMERSIBLE

Active participation in the oceanographic research allows for a rare opportunity to engage with a renowned research team to seek answers to the great mysteries of this biodiverse hotspot. It may be the first time a long-lost shipwreck is discovered, document a new species, or observe the habitats of deep-diving whales and sharks.

  • Given the massive scale of the Hudson Canyon, multiple missions performed over several years will be required to document existing conditions. This longitudinal survey to collect images, video and sonar data will provide an objective basis to assess existing conditions over time and help document and preserve its submerged history. 

  • The exploration team will conduct annual surveys of the canyon in collaboration with scientific and imaging experts from multiple organizations as part of an on-going long-term study to document the current condition of the Hudson Canyon. 

  • Create a detailed 3D model of the Canyon and portions of the Canyon using the latest multi-beam sonar and photogrammetric technology to a maximum depth of 500m. 

  • Supplement the work done on previous scientific expeditions to capture data and images for the continued scientific study of the site

  • Document the condition of the Canyon with high-definition photographs and video. 

  • Document the flora and fauna inhabiting the Canyon site for comparison with data collected on prior scientific expeditions to better assess changes in the habitat. 

Dive into the fascinating new and foreign world, rarely seen by the human eye, it may be the first time to observe a 4,000-year-old deep-sea coral, discover a long lost shipwreck, or catch a glimpse of a deep-diving whale or shark, all while seeking to better understand this subsea biodiversity hotspot filled with life thriving in the darkness.

mission DAY 1: 

Departing near New York, the crew will steam nearly 100 miles to the seaward edge of the continental shelf arriving at the top of the Hudson Canyon. In coordination with expedition leaders, scientific partners, and safety officers plans will begin for the dive objective.


mission Day 2:

Following a morning brief, the topside crew will begin the day’s dive and transfer dive crew to the submersible. During the completely untethered 3-5 hour dive, the team will descend to the targeted depth and collect data and media for scientific studies. After concluding the dive, the team will convene for a post-dive debrief and celebrate the day’s success.


mission Day 3: 

The team will arrive back in the New York area after an overnight steam from the dive site. Upon arrival, the team will resupply and begin preparations for the next mission.
