Marshes on the Margins: Developing Tidal Wetlands ...

We will investigate how the dynamic and heavily altered (e.g., through jetty construction or dredging) estuaries of Southern California will be affected by sea level rise. We will also identify ...

Modeling Favorable Habitat for Alexandrium catenel...

In Puget Sound, the toxic alga Alexandrium catenella threatens people who eat shellfish contaminated with the algal toxin. Previous studies identify “seedbeds” of Alexandrium resting stages (cysts) on the bottom ...

Modeling Hypoxia and Ecological Responses to Clima...

We are developing modeling tools that can be used to predict ecological responses to climate and nutrient input management in coastal systems. This project is part of NOAA’s Coastal Hypoxia ...

Ocean Acidification and Sea Scallops: Predicting I...

We are supporting the development of an integrated model to forecast the impacts of ocean acidification on the Atlantic sea scallop fishery. The model will predict ocean acidification trends, determine ...

Ocean Acidification in the California Current: Pre...

We are supporting the development of a management model to predict impacts of ocean acidification on food webs and the fishing economy in the California Current. The model will project ...

Predicting Impacts of Climate Change on Success of...

We are investigating how rising atmospheric temperature and changing precipitation patterns will affect coastal hypoxia (low dissolved oxygen) in Chesapeake Bay. Hypoxia in the bay, caused by an excessive influx ...

Predicting Impacts of Ocean Acidification on North...

We are supporting an effort to predict the effects ocean acidification will have on northeast U.S. shellfish. We will make projections on survival, growth, and reproduction for two species, using ...

Predicting Impacts of Sea Level Rise in the Northe...

We are assessing the impacts of sea level rise and coastal storms on marshes and oyster habitats in the northern Gulf of Mexico through the development of predictive models that ...

Quantifying the Benefits of Natural and Nature-bas...

We will analyze how marshes, submerged aquatic vegetation, and other natural features reduce wave energy and flood risks along Maryland’s Chesapeake Bay and Atlantic coastal bays. Our findings will inform ...

Salt Marsh Ecology in an Era of Sea Level Rise

Under the right circumstances, salt marshes have the ability to increase their elevation, and therefore may be able to “keep up” with sea level rise. We are working to understand ...

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 ...

Researchers Develop Tool to Predict How Coast Reco...

Barrier islands and sand dunes have long been recognized as critical ecosystems that protect coastal areas from storms, while being home to many unique plants and animals. A team of ...

Toxic Algae Not New to Puget Sound, Favor Rising T...

University and NOAA investigators have found seed-like cysts of the toxic algaAlexandrium at all depths in a sediment core taken from Sequim Bay in Puget Sound. The depths in which ...

Hardened Shorelines Reduce Fish Egg Abundance in D...

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 ...

Study Reveals Link Between Dolphin Skin Disease an...

Skin lesions on coastal dolphins are associated with water that's colder and has lower salinity, say researchers at the National Centers for Coastal Ocean Science. They analyzed photographs collected during ...

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 ...

Effects of temperature and salinity on the growth of Alexandrium (Dinophyceae) isolates from the Salish Sea

Toxin-producing blooms of dinoflagellates in the genus Alexandrium have plagued the inhabitants of the Salish Sea for centuries. Yet the environmental conditions that promote accelerated growth of this organism, a producer of paralytic shellfish toxins, is lacking. This study quantitatively ...

Effects of the Changjiang (Yangtze) River discharge on planktonic community respiration in the East China Sea

Planktonic communities tend to flourish on the western margins of the East China Sea (ECS) fueled by substrates delivered largely from the Changjiang River, the fifth largest river in the world. To study the effects of the Changjiang River discharge ...

Effects of Winds on stratification and circulation in a partially mixed estuary

Numerical experiments are conducted to investigate how axial winds affect stratification and circulation in the partially mixed estuary of Chesapeake Bay. In the absence of rotational effects, stratification in the estuary decreases following both down?estuary and up?estuary winds, but stratification ...

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 ...

Erratum to: Synthesis in estuarine and coastal ecological research

A caveat in the concluding section of our paper states that it would be impossible to provide a comprehensive sample of synthesis case studies that reflects all the major research areas in estuarine and coastal science. In retrospect, however, we ...

Estimates of the Direct Effect of Seawater pH on the Survival Rate of Species Groups in the California Current Ecosystem

Ocean acidification (OA) has the potential to restructure ecosystems due to variation in species sensitivity to the projected changes in ocean carbon chemistry. Ecological models can be forced with scenarios of OA to help scientists, managers, and other stakeholders understand ...

Evaluating confidence in the impact of regulatory nutrient reduction on Chesapeake Bay water quality

Excess nutrients derived from anthropogenic activity have resulted in the degradation of coastal water quality and an increase in low-oxygen and hypoxic events worldwide. In an effort to curb these impacts and restore water quality in the Chesapeake Bay, a ...

Evaluating estuarine habitats using secondary production as a proxy for food web support

The management, restoration, and conservation of estuarine habitats would benefit from knowledge of habitat-specific functions that reflect important ecosystem services. Secondary production may provide a comprehensive metric of food web support because it synthesizes ­contributions of local primary production, food ...

Evaluation of Lower Green Bay benthic fauna with emphasis on re-ecesis of Hexagenia mayfly nymphs

The last historic Hexagenia specimen in lower Green Bay was officially recorded in 1955. Field surveys and Hexagenia viability studies were completed to determine if lower Green Bay could support Hexagenia re-ecesis and where in the bay egg stocking could ...
