Atlantic Canyons Team Receives Partnering Award

The NOPP Office has announced the 2015 Excellence in Partnering Award recipient: Atlantic Canyons: Pathways to the Abyss. The NOPP Excellence in Partnering Award will be presented to 54 collaborators of the Atlantic Canyons project at the 2016 Ocean Sciences Meeting in New Orleans (23 February).

 

A 23-minute HD video that includes spectacular underwater footage of deep-sea coral habitats and the newly discovered chemosynthetic communities was completed in May 2015 and is available for viewing.

The project is led by Dr. Sandra Brooke of Florida State University, Dr. Steve W. Ross of the University of North Carolina at Wilmington, and Stephen Viada of Continental Shelf Ocean Sciences Inc.

The project team consists of collaborators from private industry, government agencies, and academic institutions that coordinated the exploration and documentation of the deep-water and benthic marine habitats of two mid-Atlantic Canyons located offshore of Virginia and Maryland. This effort involved research cruises to the Norfolk and Baltimore Canyons from 2011 to 2013 that found unexpected extensive deep-water coral ecosystems, identified over 125 species of fish, discovered large swaths of chemosynthetic mussel communities, documented historically important shipwrecks off the coast of Virginia, and deployed innovative sensing technologies on the canyon floors to monitor their oceanographic characteristics.

The research findings are significant and depict a biologically rich region that had not been fully explored in the past, including historically important shipwrecks, extensive deep-sea coral communities, and a vast methane-seep ecosystem. Analysis of a year’s worth of data on the ocean’s currents, temperatures, salinity and chemistry, collected by benthic landers, will be included in a forthcoming report BOEM expects to publish in 2016, and will add to the body of knowledge about the canyons as well as the broader western Atlantic Ocean. The benthic landers were designed and engineered by researchers from the University of North Carolina Wilmington, from the Netherlands and the USGS.

The federal agencies contributed equally to the study – funding approximately $9 million total between them over three years. “The partnership demonstrates that the public and private sector can achieve far more scientifically by working together than working alone, and that partnerships can be extremely effective to meet overlapping science needs,” said Dr. Rodney E. Cluck, Chief of BOEM’s Environmental Studies Program and co-chair of the federal working group that facilitates the NOPP.

In the 19-year history of the NOPP, this is only the second time that one of its studies has received two major awards. In January 2014, Secretary of the Interior Sally Jewell presented the DOI Partners in Conservation Award to this research team. Members include CSA Ocean Sciences as the prime contractor, and lead Principal Investigators from the University of North Carolina Wilmington and Florida State University. The archaeology lead was from the University of Rhode Island, and scientists from 11 other research institutions contributed to the research. ArtWork produced the photos and videography.

Researchers completed a total of seven cruise legs with 90 at-sea days. The team conducted 414 hours of Remotely Operated Vehicle (ROV) dives and mapped 6,406 km2. An HD video documentary of the project
