NCCOS Collaboration Explores Previously Unmapped Seafloor Habitats of the Channel Islands National Marine Sanctuary

Well over 50 percent of the Channel Islands National Marine Sanctuary seafloor has yet to be mapped or characterized at a level suitable for resource management. Recently on board the NOAA ship Bell M. Shimada, NCCOS and partners worked to reduce that number. On this mission, 82 square miles were mapped and identified as priority […]

Research Cruise Investigates Ocean Acidification Effects on Deep Sea Coral

NCCOS, collaborating with NOAA’s Office of National Marine Sanctuaries, Office of Ocean Exploration Research, and Office of Coast Survey, embarked on the NOAA ship Bell M Shimada on March 13 in the Channel Islands National Marine Sanctuary (CINMS), conducting ROV surveys to characterize unexplored habitat and assess abundance and condition of deep sea corals in the face of climate […]

Hypoxia Special Session Lead by NCCOS at 2015 Aquatic Sciences Meeting

Leading a special session on advances in hypoxia modelling, scientists from NCCOS contributed to the global mission of the 2015 Aquatic Sciences (ASLO) Meeting in Grenada, Spain which focused on global and regional patterns of aquatic systems. The hypoxia special session highlighted diverse modeling approaches to a variety of issues from the development of hypoxia […]

Ocean Acidification Concerns, Information to be Aired at NE Stakeholders Workshops

The Northeast Coastal Acidification Network (NECAN) is planning an “Ocean and Coastal Acidification Stakeholder Workshop” for December 10, 2014 at the Darling Marine Center in Walpole, Maine. As a member of NECAN, NCCOS is playing a major role in the development and facilitation of the upcoming workshop.  The purpose of the meeting is to inform […]

How Climate Change Could Impact Harmful Algal Blooms

Harmful algal blooms (HABs) are projected to increase as sea surface temperatures rise and ocean acidification continues according to Dr. Alan Lewitus, of NOAA’s National Centers for Coastal Ocean Science. His findings were shared during a symposium at George Mason University in October which covered such topics as climate change and extreme weather effects on […]

NCCOS and Partners Explore Climate-Related Thresholds and Tipping Points

Stakeholders expressed concerns related to climate thresholds and tipping points for coastal systems through a workshop held at the Hollings Marine Lab August 18-19, 2014. Representatives from the National Centers for Coastal Ocean Science, other National Ocean Service (NOS) offices, coastal management groups, and academia discussed the application of tipping point concepts for coastal managers, and associated […]

Coastal Ocean Acidification: The Other Eutrophication Problem

Eutrophication, or increased nutrient loading to estuaries, causes algae to bloom and consequently coastal hypoxia (low oxygen waters) when the algal biomass decomposes. Often overlooked, eutrophication can also produce carbon dioxide, which leads to a lowering of seawater pH (or increasing acidity). A recent invited paper by scientists supported by NCCOS and the NOAA Ocean Acidification Program shows low […]

Declining Oxygen Levels Threaten Oysters in Chesapeake Bay

NCCOS-sponsored research by the Smithsonian Institution Environmental Research Center (SERC) reveals low dissolved oxygen (hypoxia) hampers oysters’ ability to fight Dermo, a disease that has ravaged oysters throughout the Chesapeake Bay, resulting in up to two to three times more infected oysters than in waters with normal oxygen levels. Hypoxia is commonly studied on large geographic […]
