NCCOS Supported HAB Sensors Highlighted at NOAA Emerging Technologies Workshop

NCCOS efforts to provide early warnings as well as effective monitoring and forecasting of harmful algal blooms  through the use of the Imaging Flow Cytobot (microscope-in-a-can) and the Environmental Sample Processor (lab-in-a-can) were highlighted at a recent NOAA Emerging Technologies for Observations Workshop convened by the NOAA Observing Systems Council. Two presentations in particular detailed how NCCOS […]

NCCOS Briefs Environmental Legislators on Harmful Algal Blooms

Earlier this month, Dr. Quay Dortch (manager of the NCCOS Ecology and Oceanography of Harmful Algal Blooms Program) addressed the Oceans and Coast sub-group of the National Caucus of Environmental Legislators (NCEL). At the Chicago meeting of the sub-group, Dortch described the causes and impacts of harmful algal blooms, federal and state responses, and recommended incorporating […]

NCCOS, Partners Prepare Harmful Algal Bloom Sensor for First-ever Deployment in Lake Erie

NCCOS scientists and their partners have completed technical preparations for the first deployment of an Environmental Sample Processor (ESP) in the Great Lakes. The ESP—already in use on the U.S. East and West Coasts—is an autonomous, underwater robot that can detect harmful algal bloom cells and toxins in water samples that it collects and analyzes. […]

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; […]

Harmful Algal Bloom Action Plan Developed for Long Island

A public symposium and expert workshop was held on Long Island, NY, May 17-18, 2016 with the goal of developing a harmful algal bloom (HAB) action plan for Suffolk County. Three NCCOS-funded scientists along with two NOAA scientists attended the symposium and workshop, all providing expertise and suggestions for the plan. Long Island’s coastal waters and lakes often […]

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 […]

Risk of Shellfish Toxicity Predicted by Temperature and Salinity

A new study shows that water temperature and salinity can indicate the likely occurrence of toxic Alexandrium blooms (a type of harmful algae) in the U. S. Pacific Northwest. As shellfish become contaminated with the toxins produced by these harmful algal blooms (HABs), researchers and shellfish managers can use these findings to predict shellfish toxicity, which causes illness or even […]

Offshore Sewage Release in Southern California Brings Unexpected Result

A scheduled sewage release off Los Angeles provided a unique opportunity to study before and after impacts of massive nutrient injection into coastal waters. Researchers hypothesized large, potentially harmful algal blooms (HABs), would result from the discharge. The sewage release was extensively studied by NCCOS scientists, sponsored researchers, and partner agencies, and the results were not […]
