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 […]

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 […]

NCCOS Projects at the Forefront of Numerical Estuarine Modeling

Scientists’ use of simulation models has increased during the past several decades as a widely accepted tool for investigations into estuarine dynamics. A recently published scientific review paper, authored by NCCOS-sponsored scientists, outlines the progress and accomplishments of coupled hydrodynamic-ecological estuarine modeling. Many NCCOS-sponsored foundational modeling studies are featured in the review paper. Findings show that while most […]

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 […]

Annual Lecture Informs Long Island Citizens of Water Quality Threats

Over the last century, Long Island coastal bays, once home to some of the nation’s most productive shellfisheries, have faced a series of environmental threats. The primary culprit appears to be excess nitrogen entering the waters—from fertilizer runoff to septic system effluent—that fuels excessive algal growth, reducing water quality and degrading bay ecosystems. These algal […]

Long Island Shellfish Industry Briefed on Climate Impacts

On March 2, 2016, approximately 20 people involved in the shellfish industry on Long Island, NY met with Dr. Chris Gobler at his Stony Brook University laboratory to learn about some of the threats climate change could pose to shellfish hatchery and grow-out operations. Participants included county shellfish managers, town hatchery operators, private shellfish companies, […]

Gulf of Mexico Phytoplankton Communities Altered after Deepwater Horizon Oil Spill

On April 20, 2010, an explosion on the Deepwater Horizon oil drilling platform released millions of barrels of oil into the Gulf of Mexico, making it the largest marine oil spill in U.S. history with documented negative impacts to zooplankton, fish, birds, sea turtles, and marine mammals. Now, new research partially funded by NCCOS has disclosed negative impacts […]

Scientist and Television Station Report Long Island Water Quality Index Weekly

An NCCOS-sponsored scientist partnered with a Long Island television station to create a public water quality index that keeps citizens informed of local water conditions. The online, interactive index provides weekly reports on six water quality parameters—dissolved oxygen, water clarity, temperature, chlorophyll, fecal bacteria, and harmful algal blooms (HABs)—in more than 25 water bodies in and […]
