Evaluating Nature-Based Solution Performance

We are evaluating the performance of three types of nature-based solutions: oyster reefs, coral reefs, and wetlands created from dredged sediments. We will examine project sites five or more years ...

Evaluating the Efficacy of Island Restoration and ...

We are assessing how the effort to restore the footprint of Swan Island in Chesapeake Bay with dunes and dredged sediments is affecting ecosystems that surround the island and the ...

Evaluation of Coral Reef Restoration Success at Mi...

Diver James Emm (FKNMS-FIU) collects photographs of Eastern Dry Rocks reef near Key West, Florida, as part of a joint FKNMS-NCCOS field mission. The area will be restored as part ...

Researchers collect vegetation samples in the high marsh habitat at Deal Island, MD A sediment core taken from 1m below the surface of the saltmarsh at Deal Island, MD. "Blue ...

Right Plants in Right Places Key to Island Restora...

Natural breakwaters — such as marshes, islands, and oyster reefs — help protect people and property from coastal flooding by damping wave energy and slowing storm surge. Despite these advantages, ...

Data & Publications

Biotic resistance, disturbance, and mode of colonization impact the invasion of a widespread, introduced wetland grass

Disturbance and biotic resistance are important factors driving plant invasions, but how these factors interact for plants with different modes of colonization (i.e., sexual and asexual) is unclear. We evaluated factors influencing the invasion of nonnative Phragmites australis, which has ...

Diel differences in abundance and diversity of fish species and blue crab (Callinectes sapidus) in the sandy beach shore zone of lower Delaware Bay

Diel sampling was conducted during June–September 2013, in the shore zone and adjacent nearshore zone of Delaware Bay, Delaware, to identify day and night changes in nekton density, species richness, and the species assemblage. Mean species richness and total nekton ...

Direct and indirect impacts of shoreline development on shallow-water benthic communities in a depauperate estuarine system

Modification of natural coastlines is prevalent as human coastal populations swell and effects of global climate change become clearer. We investigated effects of shoreline hardening and environmental factors on benthic infauna and trophic structure in the Patuxent River, Maryland, a ...

Ecological Assessment of the Beneficial Use of Dredged Sediments for Island Restoration: Mordecai Island, Barnegat Bay, NJ

Scientists from the NOAA National Centers for Coastal Ocean Science (NCCOS) documented sediment and soil characteristics, erosion rates and biological communities within the sediment placement region and in undisturbed inter‐and subtidal regions of Mordecai Island from 2017 – 2019. The ...

Effects of Local Shoreline and Subestuary Watershed Condition on Waterbird Community Integrity: Influences of Geospatial Scale and Season in the Chesapeake Bay

In many coastal regions throughout the world, there is increasing pressure to harden shorelines to protect human infrastructures against sea level rise, storm surge, and erosion. This study examines waterbird community integrity in relation to shoreline hardening and land use ...

Effects of Local Watershed Land Use on Water Quality in Mid-Atlantic Coastal Bays and Subestuaries of the Chesapeake Bay

Nutrient inputs have degraded estuaries worldwide. We investigated the sources and effects of nutrient inputs by comparing water quality at shallow (< 2m deep) nearshore (within 200 m) locations in a total of 49 Chesapeake subestuaries and Mid-Atlantic coastal bays ...

Effects of Shoreline Alteration and Other Stressors on Submerged Aquatic Vegetation in Subestuaries of Chesapeake Bay and the Mid-Atlantic Coastal Bays

Submerged aquatic vegetation (SAV) provides many important ecosystem functions, but SAV has been significantly reduced in many estuaries. We used spatial–statistical models to identify estuarine shoreline characteristics that explain variations in SAV abundance among subestuaries of the Chesapeake Bay and ...

Effects of shoreline stabilization and environmental variables on benthic infaunal communities in the Lynnhaven River System of Chesapeake Bay

Coastlines worldwide are being altered due to shoreline hardening and stabilization and while highly altered systems are subject to change, variability exists in how shoreline hardening affects benthic communities depending on the landscape features of the system and regional production ...

Egg Deposition by Atlantic Silverside, Menidia menidia: Substrate Utilization and Comparison of Natural and Altered Shoreline Type

Egg deposition by the intertidal spawning fish Atlantic silverside (Menidia menidia) was compared among six shoreline types (Spartina alterniflora, Phragmites australis, sandy beach, riprap, riprap-sill, and bulkhead) and various substrates. In spring 2010, M. menidia egg density was measured daily ...

Environmental factors influencing d13C and d15N in three Chesapeake Bay fishes

Stable isotope analysis has become a common tool for mapping trophic relationships, describing foodweb changes, and assessing ecosystem health. Clear interpretation of stable isotopes is facilitated by understanding how environmental factors can affect isotopic values; in estuarine systems, these factors ...
