Congressional Interest in Harmful Algae and Dead Zone Bill Prompts Hearing

In June 2011, a House of Representatives subcommittee on energy and environment unveiled a bill to reauthorize research on hypoxic “dead zones” and harmful algal blooms (HABs). During a hearing on the legislation, lawmakers listened to officials from NOAA and the U.S. Environmental Protection Agency, experts on the Chesapeake Bay, and a scientist from the […]

New Pollution Scoring System Helps Identify Top Targets for Clean-Up

New published research by scientists at the National Centers for Coastal Science demonstrates an improved approach for calculating and comparing bioeffects levels in different places. Using a single numerical score, rather than the traditional system based on 3 distinct data sets (benthic community structure, sediment contamination, and sediment toxicity, known as the sediment quality triad) […]

‘Day-Night Swings’ of Low Oxygen Impact Shallow Water Habitats and Animals: Past and Future Investigations

Hypoxia is a major concern for many of the nation’s waters Hypoxia occurs when dissolved oxygen (DO) in the water becomes too low to support most life or compromises the growth, reproduction and immune responses of organisms.  Although some hypoxic zones can develop naturally, many such zones have worsened (and many others initiated) by excess […]

Major Accomplishments of 2010

The National Centers for Coastal Ocean Science (NCCOS) supports competitively-funded, regional, multiyear, multidisciplinary ecosystem research, modeling, and information delivery activities to improve predictions and management decisions in the coastal ocean and Great Lakes.  In 2010 NCCOS advanced understanding and developed tools for management in three major research areas: hypoxia, deep light-dependent coral reefs, and harmful […]

Researchers Examine Night and Day Swings in Oxygen Depletion on Finfish and Oyster Habitat

NCCOS has awarded a team of researchers to predict the impact of hypoxia on commercially and ecologically important finfish and oysters living in the shallow waters of Chesapeake Bay. The project is a planned five-year grant estimated at nearly $1.6 million. The Smithsonian Institution will lead a team on this effort that includes the University of […]

New Research Aims to Unravel How Nutrients Drive Toxic “Brown Tides”

NOAA has awarded Massachusetts-based Woods Hole Oceanographic Institution $120,000 as part of an anticipated three-year, nearly $500,000 project, to determine how nitrogen and phosphorus promote brown tides on the East Coast. Funds were awarded through the interagency Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, represented at NOAA by the National Centers for Coastal […]

Ocean ‘Dead Zones’ on the Rise – NYTimes.com

Coastal oceans are being starved of oxygen at an alarming rate, researchers are reporting, with vast stretches of water along the seafloor depleted of oxygen to the point that they can barely sustain marine life. The main culprit, scientists say, is nitrogen-rich nutrients from crop fertilizers that spill into coastal waters by way of rivers […]
