Fish movement and the spatial and temporal dynamics of hypoxia determine hypoxia exposure and the effect of poor water quality on nursery habitat function. Although water quality criteria for dissolved oxygen (DO) are well defined, hypoxia exposure of juvenile estuary-dependent ...

The NCCOS Regional Ecological Assessments (REA) and NOAA National Benthic Inventory (NBI) include observations of water quality, sediment quality, fish and shellfish tissue chemical contaminants, and benthic infaunal abundance obtained from studies conducted since 1991 by NOAA and partnering institutions ...

The purpose of this manual is to provide a framework for the assessment of ecosystem health that may be adapted, or used in whole or part for application to other regions. Methods are provided for all aspects from sampling design ...

This document contains the results and analysis from the fourth national coastal assessment, published in 2012 ...

Hypoxia has become a world-wide phenomenon in the global coastal ocean and causes a deterioration of the structure and function of ecosystems. Based on the collective contributions of members of SCOR Working Group #128, the present study provides an overview ...

This dataset provides seasonal spatial rasters of median predicted long-term (1978-2016) relative density of 47 marine bird species throughout the US Atlantic Outer Continental Shelf (OCS) and adjacent waters at a 2-km spatial resolution. Three indications of the uncertainty associated ...

NOAA's National Centers for Coastal Ocean Science (NCCOS) works in partnership with other federal agencies and coastal states to conduct assessments of ecological condition and potential stressor impacts throughout our Nation’s estuaries, coastal-ocean waters, and NOAA protected areas; carry out ...

Multi-year nitrogen (N) and phosphorus (P) budgets were developed for the Patuxent River estuary, a seasonally stratified and moderately eutrophic tributary of Chesapeake Bay. Major inputs (point, diffuse, septic, and direct atmospheric) were measured for 13 years during which, large ...

Increased natural and anthropogenic stresses have threatened the Earth’s ability to meet growing human demands of food, energy and water (FEW) in a sustainable way. Although much progress has been made in the provision of individual component of FEW, it ...

Dissolved oxygen is a keystone molecule that is involved in the production, consumption, and cycling of organic matter and inorganic elements in the aquatic environment. The majority of multicellular plants and animals in coastal aquatic ecosystems require oxygen for proper ...
