Estuarine Living Marine Resources: Mid-Atlantic regional distribution and abundance (NCEI Accession 0162403)

This is the Mid-Atlantic regional component of NOAA?s Estuarine Living Marine Resources (ELMR) Project, a national database of ecologically and economically important fishes and invertebrates in the Nation's estuaries. The distribution and relative abundance are depicted in a consistent format ...

Estuarine salinity zones in US East Coast, Gulf of Mexico, and US West Coast from 1999-01-01 to 1999-12-31 (NCEI Accession 0127396)

These unprojected (geographic coordinates) 3-Zone Average Annual Salinity Digital Geographies are based on analysis of long-term salinity data for 147 estuaries of the contiguous United States. Each estuary is subdivided into three zones between the head(s) of tide, and the ...

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 ...

Long-term monitoring of ecological conditions in Gray’s Reef National Marine Sanctuary: Comparison of soft-bottom benthic assemblages and contaminant levels in sediments and biota in spring 2000 and 2005

As part of an ongoing program of benthic sampling and related assessments of sediment quality at Gray's Reef National Marine Sanctuary (GRNMS) off the coast of Georgia, a survey of soft-bottom benthic habitats was conducted in spring 2005 to characterize ...

Long-term trends in Chesapeake Bay seasonal hypoxia, stratification, and nutrient loading

A previously observed shift in the relationship between Chesapeake Bay hypoxia and nitrogen loading has pressing implications on the efficacy of nutrient management. Detailed temporal analyses of long-term hypoxia, nitrogen loads, and stratification were conducted to reveal different within-summer trends ...

Metabolic balance between ecosystem production and consumption

This chapter reviews research on ecosystem metabolism in coastal environments, focusing on the history of methods development, spatial/temporal variations in rates, controlling factors, and application of these methods to address diverse scientific questions. Essential concepts and widely used terms are ...

Model output for deep-sea coral habitat suitability in the U.S. North and Mid-Atlantic from 2013 (NCEI Accession 0145923)

This dataset was created for potential use as an environmental predictor in spatial predictive models of deep-sea coral habitat suitability. Deep-sea corals are of particular conservation concern due to their slow growth rates and vulnerability to disturbance. This is a ...

Modeling the influence of hypoxia on the potential habitat of Atlantic sturgeon (Acipenser oxyrinchus): a comparison of two methods

Management of marine and estuarine fish and shellfish would benefit from a numerical approach that quantifies the impacts of climate variability and eutrophication. We present a proof-of-concept habitat volume model that incorporates predictions from a 3-dimensional biophysical model. Using temperature, ...
