Online Tool Explores Sea Level Rise and Coastal Marsh Health Scenarios

A new online tool developed by the University of South Carolina, with funding through NCCOS’s Ecological Effects of Sea Level Rise program (EESLR), allows users to evaluate scenarios of coastal saltmarsh health under a suite of sea level rise conditions. In addition to visualizing results through the web interface, users can download the results to […]

NOAA Awards $3.4 million to Support Coastal Community Resilience

NOAA’s National Centers for Coastal Ocean Science are awarding over $1.3 million, with an anticipated total of $3.4 million over the next four years, for research that will provide coastal managers with the science to plan for sea level rise and flooding, and improve the resilience of their communities. With increasing threats to our coasts, enhancing resilience to […]

2016 Ocean Sciences Meeting Showcases NCCOS Research

The 2016 Ocean Sciences Meeting this past winter featured the research of NCCOS scientists and sponsored principal investigators. Topics included ocean acidification, hypoxia, blue carbon, and harmful algal blooms. NCCOS scientists and sponsored researchers gave 24 oral and poster presentations and co-chaired six special sessions. The biennial Ocean Sciences Meeting consists of a diverse program covering […]

Why Nutrient-Enriched Waters Favor Large Single-Cell Algae

Ecological studies show that bottom-up (e.g., nutrient input) and top-down (e.g., grazing/predation) pressures may change the structure of aquatic ecosystems with “cascading” effects throughout the food chain. Recent research supports that zooplankton grazing in high-nutrient waters promotes the growth of larger phytoplankton over smaller species, creating a higher abundance of these larger single celled algae within the food web. Using samples […]

NOAA and Louisiana Collaborate on Mississippi River Diversion Management

The 5th Annual NOAA/Northern Gulf Institute Gulf Hypoxia Research Coordination Workshop brought together Louisiana state officials, federal and other state agencies, NGOs, and academic scientists with interests in identifying a path forward to restore Louisiana’s coastal wetlands, reduce the size of the annual Gulf of Mexico hypoxic zone, and sustain the ecological and socioeconomic benefits of […]

NCCOS Community Well-being Data Now Available

In August, an NCCOS collection of community well-being data for the Gulf of Mexico went live on NOAA’s Gulf Data Atlas. The Gulf of Mexico Coastal Community Well-being Data incorporates a variety of publicly available social, economic, and environmental quantitative data collected by federal, state, and local agencies. Data is available for the coastal states […]

Gulf of Mexico Dead Zone Larger than Predicted After Heavy June Rains

Scientists supported by NOAA NCCOS, EPA and the Gulf of Mexico Research Initiative have mapped the size of the 2015 Gulf of Mexico low-oxygen dead zone. The areal extent of hypoxia measures approximately 6,474 square miles, about the size of Connecticut and Massachusetts combined, exceeding the prediction from June. Nutrient run off from agricultural and other human […]
