Surface Elevation Trends Help Us Prepare for Climate Change

Predicting future patterns of coastal inundation from sea level rise requires knowledge of changes in sea level and changes in elevation of land surface. Surface elevation tables—mechanical devices permanently installed in wetlands—allow scientists to measure small changes in surface elevation precisely and accurately. These devices have been installed in coastal wetlands across the U.S. by […]

Project Finds Fish Prefer Natural Shorelines

The U.S. benefits from a wealth of resources and activities that depend on healthy coastal habitats. However, these habitats are being degraded by extensive hardening of shorelines due to climate-driven sea level rise, increasing shoreline development, land use changes in coastal watersheds, pollution, and invasions of non-native species.  In the Mid-Atlantic region alone, coastal development […]

Hardened Shorelines Reduce Fish Egg Abundance in Delaware Inland Bays

Atlantic silversides (Menidia menidia) prefer to deposit their eggs on native salt marsh habitat but not invasive salt marsh species, beaches, or shorelines hardened by bulkheads or rip-rap, according to a recent paper by a researcher funded by the National Centers for Coastal Ocean Science. NCCOS-supported research found approximately 94% of M. menidia eggs collected […]

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 […]
