Hardening of Shorelines in the Mid-Atlantic Focus of Meeting

Management agencies are struggling to balance the pressures of coastal development with the conservation and protection of the coastal environment. Representatives of several management groups convened on February 29 to review progress on a NCCOS project studying the ecosystem effects of shoreline hardening, and offer suggestions on linking research results to regional management and policy. This marked the second […]

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 […]

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 […]

Invasive Sea Squirts Threaten Shellfish Aquaculture

National Centers for Coastal Ocean Science researchers and their collaborators found that ten invasive tunicate species are fouling shellfish aquaculture operations along much of the U.S. East Coast, causing decreased growth rates, increased mortality, and high maintenance costs.  The survey identified the locations of highest fouling, which will be used to develop a plan to […]

Assessment Quantifies Extent of Sediment Contamination, Toxicity in Chesapeake Bay

The National Centers for Coastal Ocean Science (NCCOS) has released “Magnitude and Extent of Contaminated Sediment and Toxicity in Chesapeake Bay“, a report that provides chemical contaminant and benthic organism information useful for management planning efforts and understanding the Bay ecosystem. Sediment contaminants often pose ecological and human health risks through degraded habitats, loss of […]
