Oceanic Continental Margin Dead Zones Emerge as Threats to Coastal Waters

Declines in oxygen levels of coastal waters have accelerated in recent decades creating “dead zones” not only in more publicized nearshore areas but in open ocean offshore regions of the continental shelves and slopes. Once treated as separate phenomena and distinct fields of study, scientists now see offshore and coastal hypoxia as interconnected, resulting in […]

Model Allows Scallop Industry to Plan for Impacts of Climate Change

NCCOS-sponsored researchers have developed a user-friendly computer program to help manage the U.S. commercial Atlantic sea scallop fishery, which is threatened by progressively higher temperatures and ocean acidification. The Integrated Assessment Model (IAM) concurrently simulates ocean conditions related to temperature and ocean acidification, sea scallop population dynamics, and economic impacts on the scallop fishery. In the […]

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 […]

Sea Level Rise Visualization Tool “Tells Story” of Climate Change

NCCOS sponsored researchers at the University of Central Florida (UCF) are developing an improved web-based interactive sea level rise viewer. Interactive sea level rise viewers (ISLRVs) are map-based visualization tools that communicate the impacts of climate change-related sea level rise (SLR), associated with increased flooding, coastal erosion, storm surge damage, and saltwater intrusion. Traditional story telling uses the printed word […]

Marsh Hydrology Model Supports Hurricane Sandy Restoration

In support of restoration and resilience of marshes impacted by Hurricane Sandy, the U.S. Department of Interior (DOI) chose an NCCOS-supported forecast model to predict marsh ecology and hydrology related to combined effects from storm surge and sea level rise. The model selected was developed as part of the NCCOS sponsored Ecological Effects of Sea […]

NCCOS Completes Ecosystem Assessment of Chesapeake Bay Watersheds

NCCOS recently completed an assessment of three watersheds in the Chesapeake Bay region (Corsica, Magothy, and Rhode Rivers), exploring the linkages between dominant land-use type (agriculture, residential, and mixed-use, respectively) and aquatic ecosystem health. Habitat health was determined based on factors of water quality including dissolved oxygen, nitrogen, and phosphorous concentrations, and aquatic organism health […]

Sea Level Rise Scenario Project Wins Advanced Computing Award

The Extreme Science and Engineering Discovery Environment (XSEDE) group awarded $56,000 to an NCCOS-sponsored project that is integrating models to assess the ecological impacts of sea level rise. XSEDE selected the project to facilitate modeling sea level rise and storm surge simulations in the Gulf of Mexico. XSEDE, a National Science Foundation initiative, boasts the most […]

Incorporating Shoreline Fluctuations into Tidal Models Improves Sea Level Predictions

Research sponsored by the National Centers for Coastal Ocean Science demonstrates the importance of incorporating dynamic shoreline changes into models over time to forecast sea level change impacts. Projected sea level change impacts are often depicted by assuming coastlines migrate unaltered over time with the rising or falling sea level. While valid for hard, rocky shorelines, […]
