NCCOS scientists gave an overview of NOAA’s Ecological Effects of Sea-Level Rise (EESLR) Program at this year's annual meeting of Alabama floodplain managers held in Orange Beach, Alabama. The overview ...

NCCOS, The Nature Conservancy Create Living Shorel...

NCCOS and The Nature Conservancy partnered to create a decision-support tool for North Carolina's coastal communities that identifies where shoreline conditions are suitable to ensure successful living shoreline projects. Living shorelines use native ...

Research Shows Hardened Shorelines Threaten Seagra...

A new study funded by NCCOS shows that shoreline hardening—adding structures like seawalls and riprap in an effort to protect coastal land and property from the sea—degrades the habitat of submerged ...

Nate in My Front Yard, Sea-level Rise in My Office

Cleanup continues on Dauphin Island, Alabama, following landfall of Hurricane Nate in the region last week. Many residents of the island are just now getting access to their homes after ...

Spatial and Temporal Variation in Brackish Wetland Seedbanks: Implications for Wetland Restoration Following Phragmites Control

Chesapeake Bay tidal wetlands are experiencing a broad-scale, aggressive invasion by the non-native, clonal grass Phragmites australis. The grass is often managed with herbicides in efforts to restore native plant communities and wildlife habitat. Management efforts, however, can act as ...

Spatial-dynamics of Hypoxia and Fisheries: The Case of Gulf of Mexico Brown Shrimp

We analyze the Gulf of Mexico brown shrimp fishery and the potential impacts of a large seasonal area of hypoxia (low dissolved oxygen) that coincides with the peak shrimp season. A spatial-dynamic bioeconomic simulation embeds three biological impacts on shrimp: ...

Stable isotopes in mollusk shells as indicators of benthic respiration and freshwater penetration on the Texas-Louisiana Shelf

To investigate the potential for mollusks to serve as proxies for benthic respiration and hypoxia in the Gulf of Mexico (GOM), five gastropod (Conus austini Rehder and Abbott, 1951 and Strombus alatus Gmelin, 1791) and five bivalve (Pteria colymbus Röding, ...

Stand Age is Associated with Clonal Diversity, but Not Vigor, Community Structure, or Insect Herbivory in Chesapeake Bay Phragmites australis

Invasions are dynamic as both the invading organism and the invaded ecosystem change. Intrinsic changes to the invader (invasion process) can involve population level genetic and reproductive changes. Extrinsic changes (invasion effect) occur to the environment that is invaded (e.g., ...

Standardization and Application of an Index of Community Integrity for Waterbirds in the Chesapeake Bay, USA

In recent decades, there has been increasing interest in the application of ecological indices to assess ecosystem condition in response to anthropogenic activities. An Index of Waterbird Community Integrity was previously developed for the Chesapeake Bay, USA. However, the scoring ...

Statistical correction of lidar-derived digital elevation models with multispectral airborne imagery in tidal marshes

Airborne light detection and ranging (lidar) is a valuable tool for collecting large amounts of elevation data across large areas; however, the limited ability to penetrate dense vegetation with lidar hinders its usefulness for measuring tidal marsh platforms. Methods to ...

Support for Integrated Ecosystem Assessments of NOAA’s National Estuarine Research Reserve System (NERRS): Assessment of Ecological Condition and Stressor Impacts in Subtidal Waters of the Sapelo Island National Estuarine Research Reserve

A study was conducted in June 2009 to assess the current status of ecological condition and potential human-health risks throughout subtidal estuarine waters of the Sapelo Island National Estuarine Research Reserve (SINERR) along the coast of Georgia. Samples were collected ...

Suspended sediment projections in Apalachicola Bay in response to altered river flow and sediment loads under climate change and sea level rise

Suspended sediments, or total suspended solids (TSS), are an important factor for oyster habitat. While high concentrations of suspended sediments can cause a reduction of oyster density, some level of suspended sediment is required to supply oysters with necessary nutrients ...

Synthesis in estuarine and coastal ecological research: What is it, why is it important and how do we teach it?

During the last two decades, there has been growing interest in the integration of existing ideas and data to produce new synthetic models and hypotheses leading to discovery and advancement in estuarine and coastal science. This essay offers an integrated ...

Temporal responses of coastal hypoxia to nutrient loading and physical controls

The incidence and intensity of hypoxic waters in coastal aquatic ecosystems has been expanding in recent decades coincident with eutrophication of the coastal zone. Worldwide, there is strong interest in reducing the size and duration of hypoxia in coastal waters, ...
