Distribution of Persistent Organic Contaminants in Canyons and on the Continental Shelf off Central California

The National Centers for Coastal Ocean Science, and the Office of National Marine Sanctuaries, in cooperation with the U.S. Geological Survey (USGS), University of California Moss Landing Marine Lab (MLML), and the Monterey Bay Aquarium Research Institute (MBARI), conducted ecosystem ...

Domoic acid and fish behavior: A review

This paper provides a summary of the “state of knowledge” regarding behavioral impacts of domoic acid exposure on fish. Initial studies by authors of this paper suggested that fish are behaviorally impacted by domoic acid in the same way that ...

Dynamics and distribution of natural and human-caused coastal hypoxia

Water masses can become undersaturated with oxygen when natural processes alone or in combination with anthropogenic processes produce enough organic carbon that is aerobically decomposed faster than the rate of oxygen re-aeration. The dominant natural processes usually involved are photosynthetic ...

Ecological Condition of Coastal Ocean Waters along the U.S. Western Continental Shelf: 2003

This document provides an assessment of the status of ecological condition in coastal-ocean waters along the U.S. continental shelf, from the Strait of Juan de Fuca, WA to the Mexican border, based on sampling conducted in June 2003. The project ...

Ecosystem disruptive algal blooms of the brown tide species, Aureococcus anophagefferens and Aureoumbra lagunensis

Brown tides of the pelagophytes Aureococcus anophagefferens Hargraves et Sieburth and Aureoumbra lagunensis DeYoe et Stockwell have formed ecosystem disruptive algal blooms in shallow estuaries of the United States and South Africa for more than two decades. These algae achieve ...

Effects of hypoxia exposure on hepatic cytochrome P450 1A (CYP1A) expression in Atlantic croaker: molecular mechanisms of CYP1A down-regulation

Hypoxia-inducible factor-? (HIF-?) and cytochrome P450 1A (CYP1A) are biomarkers of environmental exposure to hypoxia and organic xenobiotic chemicals that act through the aryl hydrocarbon receptor, respectively. Many aquatic environments heavily contaminated with organic chemicals, such as harbors, are also ...

Effects of model physics on hypoxia simulations for the northern Gulf of Mexico: A model intercomparison

A large hypoxic zone forms every summer on the Texas-Louisiana Shelf in the northern Gulf of Mexico due to nutrient and freshwater inputs from the Mississippi/Atchafalaya River System. Efforts are underway to reduce the extent of hypoxic conditions through reductions ...

Effects of Nutrient Enrichment In the Nation’s Estuaries: A Decade of Change

The National Estuarine Eutrophication Assessment (NEEA) is a tool for evaluating both current eutrophic condition and the effectiveness of management actions aimed at reducing eutrophic condition. Eutrophication is caused by excess nutrients and is expressed by symptoms such as increased ...

Ensemble modeling informs hypoxia management in the northern Gulf of Mexico

A large region of low-dissolved-oxygen bottom waters (hypoxia) forms nearly every summer in the northern Gulf of Mexico because of nutrient inputs from the Mississippi River Basin and water column stratification. Policymakers developed goals to reduce the area of hypoxic ...
