Characterization of Toxic Impacts on Living Marine Resources in Tidal Rivers of the Chesapeake Bay

In 1999, the Chesapeake Bay Program completed a survey of existing data on chemical contaminants and the potential for bioeffects in 38 tidal river systems of Chesapeake Bay. This review led to the identification of 20 areas for which there ...

Chemical contaminants in corals (Pocillopora damicornis) in Tinian, CNMI

This document presents environmental data collected in August 2013 consisting of coral tissue (Pocillopora damicornis) contaminants and surface water nutrients offshore from Tinian in the Commonwealth of Northern Mariana Islands (CNMI). The study area is in and around the Tinian ...

Chronic Low-Level Domoic Acid Exposure Alters Gene Transcription and Impairs Mitochondrial Function in the CNS

Domoic acid is an algal-derived seafood toxin that functions as a glutamate agonist and exerts excitotoxicity via overstimulation of glutamate receptors (AMPA, NMDA) in the central nervous system (CNS). At high (symptomatic) doses, domoic acid is well-known to cause seizures, ...

Coastal ecosystem assessment of Chesapeake Bay watersheds: A story of three rivers, the Corsica, Magothy, and Rhode

This assessment explored linkages between land use and aquatic ecosystem health. Three watersheds (Corsica, Magothy, and Rhode rivers) with variable dominant land-use patterns (agriculture, suburban/residential, and mixed-use, respectively) were examined. The health of each habitat was assessed using a suite ...

Coastal eutrophication near the Mississippi river delta

Changes in delivery of river-borne nutrients such as dissolved phosphate, nitrate and silicate, owing to land-use changes and anthropogenic emissions, are known to result in eutrophication1— enhanced phytoplankton blooms—and more severe hypoxic events2–1 in many enclosed bays and seas. Although ...

Dispersal of Mississippi and Atchafalaya Sediment on the Texas-Louisiana Shelf: Model Estimates for the Year 1993

A three-dimensional coupled hydrodynamic-sediment transport model for the Texas–Louisiana continental shelf was developed using the Regional Ocean Modeling System (ROMS) and used to represent fluvial sediment transport and deposition for the year 1993. The model included water and sediment discharge ...
