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 […]

Sea Level Rise Shoreline Model Reconstructs Past to Predict Future

A unique NCCOS sponsored study, recently published in Contenental Shelf Research, examined the influence of sea level rise (SLR) on historic mainland and barrier island beaches and salt marshes of Mississippi’s Grand Bay in Mississippi Sound. The research used historical data to investigate how excess erosion in Grand Bay and SLR will affect any future changes […]

NCCOS Sponsors 20 New Research Projects

NCCOS awarded nearly $4.5 million in new research grants while maintaining sponsorship of 42 continuing projects during 2015 for a total of $8.2 million in funding for innovative research. All of the endeavors address significant and complex coastal issues. The projects were selected using a rigorous, competitive, and peer-review process. The cutting-edge research will provide critical […]

Toxic Algae and Their Seaweed Hosts May Predict Ciguatera Fish Poisoning

New research shows that different Caribbean species of Gambierdiscus—the microscopic marine algae most often associated with ciguatera fish poisoning (CFP)—demonstrate different growth and attachment behaviors with different coral reef seaweed hosts. The findings are helping researchers understand how ciguatoxin moves through the food web, information which, in turn, could be used to improve reef sampling and monitoring […]

New FY 2016 Funding Opportunity Available to Research Ecological Effects of Sea Level Rise

NCCOS has created a funding opportunity for Fiscal Year 2016 for researchers to assess the ability of natural and nature-based coastal features to mitigate the effects of sea level rise and coastal inundation. The geographic scope of this funding is limited to coastal regions of southern California (defined as San Louis Obispo County south to the U.S./Mexico border) and […]

New Technology Documents Rapid Phytoplankton Response to Tropical Storms and Hurricanes

A scientific study funded by NCCOS’ ECOHAB program, shows phytoplankton community structure changing rapidly, often by the hour, as tropical cyclones pass by. A revolutionary sampling instrument, the Imaging FlowCytobot (IFCB) allows hourly real-time continuous observation of phytoplankton changes. Over time the IFCB provides an extraordinary view of phytoplankton community structure. Prior studies of phytoplankton responses to […]
