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 […]

NCCOS Living Shorelines Research Attracts International Audience

A delegation from the Ecosystem Conservation Society of Japan (ECS-J) recently visited the NCCOS laboratory in Beaufort, NC to learn about living shorelines.  ECS-J is the largest conservation group in Japan, and works with environmental organizations, government agencies and research groups in Japan and abroad to promote environmental conservation. The visit was prompted by the […]

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 […]

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 […]
