Scientists Peer into Alaska’s Ocean Depths to Assess Water Before Drilling

In an effort to monitor the condition of Alaska’s offshore resources, scientists from the National Centers for Coastal Ocean Science are sampling the water and seafloor life of the Chukchi Sea. The three-week research cruise supports the state’s Department of Environmental Conservation, which is gathering baseline data on areas proposed for oil and gas surveys […]

Invasive Mussels Linked to Nutrients in Great Lakes

The Great Lakes have multiple stresses acting on them, but offshore and nearshore systems may show different trends in relation to stresses.  A new paper by NCCOS-supported researchers links these trends with invasive mussels.  Mussels filter waters coming into coastal embayments, and can pull phosphorus out of the water column and deposit it into nearshore […]

Threat to Common Gulf of Mexico Fish Stir Fears of a Domino Effect

Atlantic croaker, one of the most abundant fish in the Gulf of Mexico, are starting to exhibit changes that appear to be related to the massive summer “Dead Zone.” A NOAA-sponsored study found croakers exposed to low oxygen for as few as 10 weeks underwent hormonal alterations that transformed some of their female reproductive tissue […]

High-Frequency Radar System Provides Important Information About West Coast Ocean Currents

High Frequency Radar (HFR) can resolve ocean currents to a scale of 1 kilometer and extend out to approximately 150 kilometers offshore.  In addition to oceanographic studies, HFR has proven useful to applications such as supporting oil spill response, search and rescue, fisheries, and coastal discharge assessment. Now, through the support of the Integrated Ocean […]

Dolphin, Whale Blubber Harbors Chemicals : Discovery News

Toxic chemicals are accumulating in the bodies of dolphins and whales, according to two new studies, and concentrations tend to be highest in the most populated and developed areas. The findings are not necessarily surprising. Scientists have known for years that the blubber of marine predators harbors pollutants. Still, the new studies offer the most […]

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) […]

Great Lakes Restoration Initiative – NOAA Program Expands into EPA Designated “Areas of Concern”

Scientists from the National Centers for Coastal Ocean Science and the Great Lakes Environmental Research Laboratory completed the second phase of mussel and sediment collections from Lakes Superior, Michigan, Huron, and St. Clair, and the Detroit, St. Clair and St Mary’s Rivers in September. Two teams and two boats traveled a combined distance of nearly […]

Long-term Data Set the Stage for Coastal Marine Spatial Planning in Puerto Rico

A long-term data series collected by scientists with the National Centers for Coastal Ocean Science may help the Commonwealth of Puerto Rico as it moves ahead with coastal marine spatial planning (CMSP) efforts. Initial conversations are now being held with the Department of Natural and Environmental Resources and the University of Puerto Rico to utilize […]
