Renewed Interest to Study Ciguatera Risks in Papahanaumokuakea Marine National Monument

Dr. Alison Robertson, an NCCOS ECOHAB sponsored ciguatera expert with the University of South Alabama and Dauphin Island Sea Lab (USA\DISL), is helping the NOAA Office of National Marine Sanctuaries (ONMS) assess human health threats related to ciguatera fish poisoning in island waters within the Papahanaumokuakea Marine National Monument (PMNM). Ciguatera is a major, if not the […]

Multiple Marine and Freshwater Algal Toxins Documented in Southern California

NCCOS-sponsored scientists recently documented the occurrence of several, potentially harmful cyanobacteria and associated toxins at the land-sea interface along the southern California coast. Their newly published findings in the journal Toxins reveal a previously unrecognized, potential human health threat from cyanotoxins in our coastal waters, raising new concerns for recreation, harvesting of finfish and shellfish, […]

NCCOS Research on Display at 2017 Aquatic Sciences Meeting

From February 26 to March 3, 2017 the Association for the Sciences of Limnology and Oceanography (ASLO) held its biennial Aquatic Sciences Meeting in Honolulu, Hawai′i. NCCOS scientists and sponsored investigators shared their research results with thousands of limnologists and oceanographers from around the world. Topics included harmful algal blooms, hypoxia, science to management applications, […]

Risk of Toxic Shellfish on West Coast Increases with Water Temperature

High levels of domoic acid, a shellfish toxin, are correlated with warmer ocean temperatures offshore of Oregon and Washington. An NCCOS-supported research team led by scientists from Oregon State University, the University of Oregon, and the Oregon Department of Fish and Wildlife found an association between domoic acid levels in shellfish and climate-scale warm ocean […]

Stakeholders Meet to Develop Harmful Algal Bloom Action Plan for Alaska

Alaska Sea Grant and the Alaska Ocean Observing System recently cosponsored a two-day workshop to develop an action plan for harmful algal bloom (HAB) monitoring, event response, outreach, and research in Alaska. NCCOS staff opened the workshop by providing a national perspective on HABs that set the stage for discussions of existing activities and identified […]

Establishing Sustainable and Cooperative Dead Zone Monitoring in the Gulf of Mexico

Scientists, managers, and agency personnel from 26 stakeholder agencies and institutions met to establish a sustainable multi-partner hypoxia monitoring program in the northern Gulf of Mexico at the NCCOS sponsored 6th Annual NOAA/Northern Gulf Institute Hypoxia Research Coordination Workshop. The 2012 Gulf of Mexico Hypoxia Monitoring Implementation Plan and subsequent workshops provided a foundation to move […]

Meeting Challenges in Estuarine and Coastal Ecosystem Science

Along with individual stressor-based research projects, NCCOS undertakes a broader ecosystem approach using larger, multidisciplinary research projects. A recent essay authored in part by NCCOS sponsored scientists gives perspectives on challenges and paths for advancing estuarine science; NCCOS research strives to meet these challenges. Five major research challenges were identified: (1) Maintaining and improving spatially distributed time-series datasets; […]

Environmental Variables Influence Toxic Ciguatera Algae Growth and Distribution

A new study describes optimal growth conditions for several species and strains of the benthic marine dinoflagellate Gambierdiscus and highlights how these species and strains respond differently to varying levels of salinity, light, and temperature. These environmental factors, along with suitable seafloor habitat, predict the geographic distribution of Gambierdiscus. Gambierdiscus is a genus of tropical and subtropical […]
