The Florida manatee inhabits environments in which blooms of the toxic dinoflagellate, Karenia brevis, frequently occur. K. brevis produces brevetoxins, that result in fish kills, contamination of shellfish, and respiratory ... Read More
We are estimating the economic value from natural and nature-based infrastructure investments to stabilize coastline. Using hazard risks along the U.S. Pacific Northwest coast, we are assigning a dollar value ... Read More
This project supports development for two lab-based quantitative molecular methods for more rapid, accurate detection of Alexandrium catenella resting cysts in sediment from the Gulf of Maine, Puget Sound, and ... Read More
Blooms of Alexandrium fundyense result in economic losses to fisheries, aquaculture, and pose public health risks. Typically, A. fundyense growth and toxicity are seen as dependent on light, temperature, and ... Read More
This study will use a mixed methods approach to examine how Sargassum events and their mitigation in the Caribbean affect multiple dimensions of social resilience, including economic impacts, human wellbeing, ... Read More
We are examining the impact of low-oxygen (hypoxia) stress on coral reef ecosystems. Coral reefs are in decline, and human-assisted restoration is actively trying to reverse this trend. Our project ... Read More
This project will comprehensively quantify and qualify the short- and long-term socioeconomic impacts of the 2017-2019 Karenia brevis event in Florida. It will also develop a transferable framework to inform ... Read More
We are investigating the processes that lead to hypoxia in Southern California’s lagoons, and identifying its ecological impacts. These small estuaries, which have tidal inlets that can close to the ... Read More
We will advance scientific, engineering, and policy perspectives on how sediment can be managed in coastal lowlands to reduce flood risk, bank instability, and erosion risk. We will evaluate sediment ... Read More
Harmful algal blooms of Dinophysis have recently emerged as a human health threat in the U.S., resulting in closures of shellfish harvesting to prevent Diarrhetic Shellfish Poisoning. We are working ... Read More
Sediment collection in Chiniak Bay, near Kodiak Alaska. Credit: Julie Matweyou, Alaska Sea Grant NCCOS funded partners recently completed field work in Kodiak Alaska to continue advancing a coordinated, multi-region ... Read More
Mesodinium rubrum (left cell) captured by Dinophysis cf. ovum. Modified from Mafra Jr. et al. 2016. The toxic dinoflagellate alga Dinophysis threatens human health and coastal economies through the production ... Read More
Some oceanfront landowners in Neskowin, Oregon, have chosen to use rock revetments, or rip-rap, to protect their properties from erosion. Their decision has implications for property values, public access, and ... Read More
Figure 1. The MERHAB Autonomous Research Vessel In-situ (MARVIN) deployed in Sarasota Bay in 2009. Credit FWC. A recent NCCOS-supported study observed that urea inputs into Sarasota Bay, FL influenced ... Read More
NCCOS-supported researchers from the University of Florida and Smithsonian Marine Station paired water quality sensors with coral outplants to develop data-driven criteria for selection of restoration sites in the Florida ... Read More
NCCOS-sponsored scientists combined two traditional, but often separate, modeling approaches to better characterize, track, and predict coastal hypoxia in the northern Gulf of Mexico. Their study found that “fused” geostatistical ... Read More
In a recently released book on dinoflagellates, three chapters update knowledge of and changing views for the red tide alga Karenia brevis and the estuarine Pfiesteria-like dinoflagellates Pfiesteria piscicida and ... Read More
This manual presents geographic information by state of occurrence, and descriptions of the socio-economic impact created by the invasion of nonindigenous and native transplanted animal species in the Laurentian Great Lakes and the coastal waters of the United States. It ... Read More
