  • Expedition Overview

    By Kasey Cantwell and Michael White

    Priority operating areas for the expedition.

    From May 30 through July 12, 2019, NOAA and partners will conduct a two-part, telepresence-enabled ocean exploration expedition on NOAA Ship Okeanos Explorer to collect critical baseline information about unknown and poorly understood deepwater areas of the southeastern United States.

    Priority operating areas for Leg 1 of the expedition, in yellow.

    The first leg of the Windows to the Deep 2019 expedition, taking place from May 30 to June 14, will include 24-hour per day mapping operations on NOAA Ship Okeanos Explorer focused on high-priority areas identified by the South Atlantic Fishery Management Council, NOAA, Bureau of Ocean Energy Management, and the science community.

  • Leg 2 Mission Plan

    By Kasey Cantwell, Amy Wagner, and Alexis Weinnig

    ROV Deep Discoverer

    From June 20 through July 12, NOAA and partners will conduct the second leg of the Windows to the Deep 2019 expedition, a telepresence-enabled ocean exploration expedition on NOAA Ship Okeanos Explorer to collect critical baseline information about unknown and poorly understood deepwater areas off the southeastern U.S. coast. During this expedition, our at-sea and shore-based science teams will work together to map the seafloor and observe many targeted sites for the first time.

  • Maritime Heritage Along the East Coast

    By Joseph Hoyt

    Merchant ship City of Atlanta sank in January 1942, when torpedoed by a German submarine, U-123.

    There is perhaps no greater potential for archaeological discoveries in U.S. waters than along the Eastern Seaboard. This region has been host to human activity since before the Last Glacial Maximum, when the shoreline approximated what is now the continental shelf, the bottomlands themselves once homes, hunting grounds, and sacred places. The prospect of identifying indigenous sites in this area has long filled archaeologists and living native descendants with hope.

  • Mysteries of the Deep: Exploring Canyons Along the Atlantic Margin

    By Amanda Demopoulos, Benthic Research Ecologist, U.S. Geological Survey

    The steep ledges of Norfolk Canyon proved to be home to a large diversity of life.

    Submarine canyons are found throughout the world, representing complex seafloor features that link the upper continental shelf to the abyssal plain. They punctuate the margin by incising the shelf, creating scenic seascapes reminiscent of their terrestrial counterparts.

  • NOAA’s Southeast Deep Coral Initiative (SEDCI): Exploring Deep-Sea Coral Ecosystems Off the Southeast United States

    By Daniel Wagner

    A dense community of black corals, octocorals, and crinoids at 122 meters (400 feet) depth on Elvers Bank in the northwestern Gulf of Mexico.

    In 2016, NOAA launched a new four-year initiative to study deep-sea coral and sponge ecosystems across the Southeast United States, a region that includes the U.S. federal waters of the Gulf of Mexico, South Atlantic Bight, and Caribbean Sea. This multidisciplinary effort, known as the Southeast Deep Coral Initiative (SEDCI), is led by a NOAA team from multiple line offices that work in close collaboration with partners from federal and academic institutions. Funding for SEDCI activities is provided primarily by NOAA through the Deep Sea Coral Research and Technology Program.

  • An Update on Cold Seeps in the Northwestern Atlantic Ocean

    By Cheryl Morrison

    Images of bubble plumes from gaseous seeps collected using water column acoustic reflectivity observations from NOAA Ship Okeanos Explorer Northeast and Mid-Atlantic Canyons Expedition.

    During the Windows to the Deep 2019: Exploration of the Deep-sea Habitats of the Southeastern United States expedition, the mission team will try to explore at least one cold seep site near the North Carolina coast. Cold seeps occur where highly saline and hydrocarbon-rich fluids, such as methane and sulfides, escape from the seafloor at close to ambient temperatures.
