Assessing Emerging Algal Toxin Threat in Washington State Waters

In early June 2016, NOAA and Washington State partners begin a four-month long effort to monitor shellfish and water every week at six locations around Puget Sound and on the Pacific coast. The team plans to measure concentrations of marine algae and their associated lipophilic (fat soluble) toxins, which can accumulate in shellfish and cause […]

Keeping Up With Rising Seas

Scientists predicted wetland soil accretion (or growth) rates in relation to predicted sea level rise using a model and data from numerous tidal salt and freshwater wetlands around the United States. The model results, published in Earth’s Future, suggested that, on average, softer organic components of East Coast marsh sediments do not accrete  fast enough in volume and height […]

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 […]

Together Hypoxia and Ocean Acidification Equal a Double Whammy for Marine Life

Conditions resulting in low dissolved oxygen (DO) in marine systems, also known as hypoxia, are a common occurrence in oceans around the world. Ocean acidification (OA), which results in lower pH, is a newer phenomenon, but often co-occurs with hypoxia due to elevated water temperatures and accelerated nutrient delivery from land. A new review of the effects of hypoxia […]

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 […]

Can Mesophotic Coral Ecosystems Serve as Lifeboats for Shallow Reefs?

On May 24, 2016, the United Nations Environment Programme released a new report on mesophotic coral ecosystems (MCEs) during a coral reef media roundtable at the second session of the United Nations Environmental Assembly (UNEA-2) in Nairobi, Kenya. The document, Mesophotic Coral Ecosystems: A lifeboat for coral reefs?, edited by GRID-Arendal and NOAA, represents contributions […]

Acidification Increases Sensitivity to Hypoxia in Important Forage Fishes

NCCOS sponsored research focusing on the combined effects of low dissolved oxygen and ocean acidification finds that acidification can increase fish sensitivity to hypoxia. This has important implications for increasing atmospheric carbon dioxide effects on our marine systems and may indicate that official dissolved oxygen regulatory criteria do not protect living resources as intended. Hypoxia, or […]

NOAA Supports Florida’s Monitoring of Brown Tide in Indian River Lagoon

NCCOS has approved a Harmful Algal Bloom Event Response project that will enhance state efforts to monitor and assess the extent of an active bloom of Aureoumbra lagunensis algae, also known as brown tide, in Florida’s northern Indian River Lagoon system. A massive fish kill last month was attributed to low dissolved oxygen conditions created […]
