Government Regulators Consider Negative Impacts of Shoreline Armoring

Results from a six-year NCCOS sponsored study on the impacts of different approaches to erosion control – seawalls, riprap, and “living” shorelines – on submerged aquatic plants, crabs, fish, ducks, and geese in Chesapeake Bay has prompted government regulators to consider the cumulative impacts of shoreline armoring projects in upcoming management decisions. Scientists have presented […]

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 […]

New Predictive Tool Helps Managers in Lake Michigan’s Green Bay

A new predictive management tool addresses an issue that confronts Wisconsin resource managers, farmers, environmentalists and fish scientists – too many nutrients, mainly phosphorus, from the Lower Fox River washing into Green Bay leading to hypoxia and harmful algal blooms. The model tool, developed by the Green Bay hypoxia and climate change project and funded by NCCOS’ […]

The Future of Algae Bloom Monitoring Technology

Technology developed with NCCOS funding is rapidly advancing harmful algal bloom (HAB) monitoring capabilities nationwide. These cutting edge detection tools are now commercially available and transitioning them to sustained management operations is the new norm. Recently a U. S. National Park Service (NPS) funded study benefited from the use of the NCCOS-developed “underwater microscope” Imaging […]

Scientists Assess Impacts of Bioluminescent Algae on Chesapeake Bay Fisheries

Around mid-August, a bloom of the dinoflagellate Alexandrium monilatum appeared in lower Chesapeake Bay and its tidal tributaries. It is unclear whether the bloom originated there or was carried there by currents. Since it first appeared in the York River and at the oceanfront off Sandbridge Beach, the bloom has been observed miles into lower […]

West Coast Harmful Algal Bloom Explained

An unprecedented West Coast harmful algal bloom (HAB) continues, hurting Pacific Coast marine wildlife and causing economic losses to commercial shell fishers from Alaska to California. NCCOS sponsored scientists are participating in the event response and providing information to the public. Recently, NCCOS sponsored scientist Dr. Vera Trainer of NOAA Fisheries joined Washington and Oregon […]
