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 […]

2016 Ocean Sciences Meeting Showcases NCCOS Research

The 2016 Ocean Sciences Meeting this past winter featured the research of NCCOS scientists and sponsored principal investigators. Topics included ocean acidification, hypoxia, blue carbon, and harmful algal blooms. NCCOS scientists and sponsored researchers gave 24 oral and poster presentations and co-chaired six special sessions. The biennial Ocean Sciences Meeting consists of a diverse program covering […]

Robotic Environmental Sample Processor Conserves Samples for HAB Species Identification

Sponsored researchers with the NCCOS ECOHAB project looking at regional harmful algal bloom “hotspots” off coastal California are testing the feasibility of using a robotic water quality and toxin detection device, the Environmental Sample Processor or ESP, to collect the glass cells (silicon frustules) of the diatom Pseudo-nitzschia for species identification and assessing geographic distribution. Certain species […]

California Ocean Protection Council Briefed on Harmful Algal Bloom Impacts

At a recent meeting of the California Ocean Protection Council (OPC), a panel of researchers and managers briefed the council on the Summer 2015 West Coast harmful algal bloom (HAB) event and other troubling changing ocean conditions. The presentation highlighted the value of past and current NCCOS competitive HAB programs. These program investments in modeling, monitoring, observing and […]
