Coastal Ecosystem Susceptibility to Nutrient Pollu...

We studied the estuaries of the U.S. East Coast and Gulf of Mexico to determine which coastal areas are most vulnerable to changes in nutrient input. We modeled the environmental ...

A Reduced Complexity, Hybrid Empirical-Mechanistic Model of Eutrophication and Hypoxia in Shallow Marine Ecosystems

Numerical simulation models have a long history as research tools for the study of coastal marine ecosystems, and are increasingly being used to inform management, particularly related to nutrient-fueled eutrophication. Demand for modeling assessments is rapidly increasing, and managers need ...

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 ...

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 ...

Estuarine classification and response to nitrogen loading: Insights from simple ecological models

Estuaries exhibit a large range in their responses to nitrogen loadings determined in part by characteristics of the driver, such as magnitude and frequency, but also by such intrinsic characteristics as physical/chemical factors (e.g., depth, volume, hypsometry, salinity, turbidity) and ...

Exploring estuarine eutrophication sensitivity to nutrient loading

The sensitivity of surface chlorophyll (Chl) and bottom water dissolved oxygen (DO) to total nitrogen (TN) load was investigated using a Bayesian?based process model fit to data from a range of estuaries. The model was used to test if the ...

Harmful Algal Blooms along the North American West Coast Region: History, trends, causes, and impacts

Along the Pacific coast of North America, from Alaska to Mexico, harmful algal blooms (HABs) have caused losses to natural resources and coastal economies, and have resulted in human sicknesses and deaths for decades. Recent reports indicate a possible increase ...

Hypoxia-induced shifts in nitrogen and phosphorus cycling in Chesapeake Bay

We investigated interactions between hypoxia and nutrient cycling in Chesapeake Bay using quantitative analysis of long?term monitoring data covering the periods 1965?1980 and 1985?2007. The data included vertical water column profiles of temperature, salinity, NH+4, PO3?4, and O2, as well ...

Long-term decline in the calanoid copepod Acartia tonsa in central Chesapeake Bay, USA: An indirect effect of eutrophication

A long-term abundance record of the calanoid copepod Acartia tonsa in the Maryland portion of Chesapeake Bay was compiled from 1966 to 2002. A significant downward trend in the summertime abundance of Acartia tonsa was found in central Chesapeake Bay ...
