SHARED REGIONAL PRIORITIES

Marine Habitats

The Need for Action

Cold-water corals, deep submarine canyons, and a broad, sandy continental shelf are among the diverse ocean habitats of the Mid-Atlantic region. In addition to being home to wildlife like sea turtles, whales, dolphins, seabirds, fish, crustaceans, corals, and other species, these habitats support commercial and recreational fisheries and other important economic activities in the region. MARCO is working with partners to map and document the Mid-Atlantic Ocean habitats in order to maintain sustainable resource use and healthy ecosystems in light of climatic changes and increased human use pressure.

The National Oceanic and Atmospheric Administration (NOAA), in collaboration with other federal agencies and external partners, conducted a series of expeditions to survey deepwater canyons from Virginia to Maine. NOAA scientists invited MARCO to help identify priority areas that might be surveyed to help fill biological and geological informational gaps in the Mid-Atlantic. The NOAA ship Okeanos Explorer explored the deep waters of the Mid-Atlantic region, including canyons off New York, New Jersey, Delaware, Maryland and Virginia.

Identification of priority areas led to MARCO worked with scientists at the Woods Hole Oceanographic Institution (WHOI) to add genus and species level coral data from deep sea canyons off the Mid-Atlantic coast to the Mid-Atlantic Ocean Data Portal. Using towed camera technology, they explored eight of the Mid-Atlantic’s lesser-studied canyons: Ryan, Carteret, Lindenkohl, Spencer, Washington, Wilmington, Leonard and Accomac canyons.

In addition to the Portal, other outreach to bring attention to this habitat and its diverse life were developed. Take a virtual tour of the canyons with Dr. Tim Shank. The recording of “The Underwater United States: exploring life and ecosystems in the U. S. exclusive economic zone” with Dr. Shank highlights the diversity of life found in this deep-sea habitat.  

 

WHOI biologist Dr. Timothy Shank reveals what it was like to explore the canyon formations and observe coral colonies deep under water in this Ocean Stories “Tales from the Mid-Atlantic Canyons.”

“Exploring the Unexplored: Deep-Sea Canyons of the Mid-Atlantic” is a story map which is intended as an educational resource for all audiences on deep-sea canyons, corals and topography.

The VA CZM Program, as a MARCO member, funded work to help visualize shifts in fish populations on the MARCO Data Portal. See trends in fish species movement which took place since the 1970’s or project future shifts.

Work Groups/Collaborative Efforts

MARCO and MACO collaborate with governmental agencies, tribal nations and many other interested stakeholders through a series of specially focused work groups. The areas of focus that are relevant to this priority include:

Ocean Data Mapping Team (OMDT)

The Portal boasts thousands of layers of ocean data and is regularly updated with new and improved data and functions associated with marine habitats. Highlights associated with marine habitats include:
