This dataset contains video products from R/V Atlantis and Alvin submersible from the second leg of the Gulf of Alaska 2002 Expedition headed south from Kodiak, Alaska to study several unexplored seamounts in the Gulf of Alaska to understand how they formed and determine their historic history. Additional operations included species collection, habitat characterization, and studies of benthic community structures.

The 2004 Gulf of Alaska Seamount Expedition will use the deep submergence vehicle (DSV) Alvin to explore five large seamounts. Giacomini, Pratt, Welker, Denson, and Dickens seamounts stretch over a 400-nautical-mile section of the northeast Pacific, called the Kodiak-Bowie Seamount Chain. Operating from a base aboard R/V Atlantis, scientists will dive to depths of up to 3,500 m to conduct a series of biological and geological investigations on these ancient volcanoes. All four of the Principal Investigators aboard this cruise were part of the Gulf of Alaska Seamount Expedition in 2002, as were other scientific researchers, many of the ship's crew, the sub's crew, and the cruise coordinator. The research foci of this mission include: - Geologic dating and characterization of the seamounts - Deep-sea coral distribution and genetics - Community ecology of deep-sea corals - Investigation of the microbial, invertebrate, and fish communities associated with the corals

This dataset contains video products from R/V Akademik Mstislav Keldysh, HOV MIR I and HOV MIR II in the Mid-Atlantic Ridge (MAR) and Charlie Gibbs Fracture Zone (CGFZ) from 2002 to 2003. The Census of Marine Life (CoML) was an international research effort that strived to assess and explain the diversity, distribution and abundance of marine organisms throughout the world's oceans.

This dataset contains video products from NOAA Ship Reuben Lasker, AUV Popoki, ROV Guru, and ROV Yogi, along the California, Oregon, and Washington Coasts from 2019-10-22 to 2019-11-07. This expedition is the second leg of the two cruises in the 2019 field season which are part of the Surveying Deep-sea Corals, Sponges, and Fish Habitat expedition, part of a series of multi-agency collaborations known as EXPRESS, short for EXpanding Pacific Research and Exploration of Submerged Systems.
