Okeanos Explorer (EX1903L2): Mid and Southeast US (ROV and Mapping) - 2019 (EM302). Windows to the Deep 2019: Exploration of the Deep-sea Habitats of the Southeastern United States was a 38-day, two-leg, telepresence-enabled expedition on NOAA Ship Okeanos Explorer to collect data on priority exploration areas identified by the ocean management and scientific communities. During the expedition, scientists explored a diversity of features with mapping and remotely operated vehicle (ROV) operations, including deep-sea fish habitats, deep-sea coral and sponge communities, midwater habitats, cold seeps, submarine canyons, submarine landslides, and other unique geological features.

Okeanos Explorer (EX1905L2): New England and Canada (ROV and Mapping) (EM302). This 21-day expedition leg will start in Halifax, Nova Scotia, on August 26, 2019, and end in North Kingstown, Rhode Island, on September 15, 2019. The expedition will include 24-hour-a-day operations, including daytime ROV dives to depths ranging between 250-3,000 meters (~820-9,843 feet), overnight mapping operations to depths of 5,000 meters (16,404 feet), as well as continuous shore-side participation via telepresence technology. ROV dives will focus on exploring submarine canyons and slope habitats, seamounts, deep-sea coral and sponge communities, midwater habitats, unique geological features, and other poorly known deep-sea habitats. Mapping operations will concentrate on seafloor and water column areas with little or no high-quality sonar data, as well as being used to support ROV operations and identify potential maritime heritage sites. Data collected on this expedition will support the development of habitat suitability models and geohazard models and enhance our understanding of poorly explored deepwater areas offshore of the U.S. Mid-Atlantic, New England, and Nova Scotia.

Okeanos Explorer (EX1905L1): New England and Canada (Mapping) - 2019 (EK60). EX1905L1 will be one of several NOAA Ship Okeanos Explorer expeditions in 2018-2020 that will contribute to NOAA's Atlantic Seafloor Partnership for Integrated Research and Exploration (ASPIRE), a major multi-year, multi-national, collaborative ocean exploration program focused on raising our collective knowledge and understanding of the North Atlantic Ocean. The NAO plays a pivotal role to humankind, providing biological and geological resources, ecosystem services, such as seafood production and climate regulation, and a route for trade and travel between Europe and the Americas.

This dataset contains oceanographic data collected in the deep water areas around the Commonwealth of the Northern Marianas Islands (CNMI). Operations for this cruise included ROV, mapping, telepresence-based remote participation, and CTD rosette operations. Operations also used the ship’s deep water mapping systems, NOAA’s two-body 6000 m remotely operated vehicle, and the ship’s high-bandwidth satellite connection for real-time ship to shore communications. Daytime ROV dives were planned every day and included high-resolution visual surveys and limited rock and biologic specimen sampling. Mapping operations were conducted overnight when the ROV was on deck and CTD casts were taken to collect more environmental information at sites of interest. Exploration operations for this cruise focused on deep-water areas around CNMI and the Marianas Trench Marine National Monument (MTMNM). This expedition helped establish a baseline of information in the region to catalyze further exploration, research, and management activities.
