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 ...

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, ...

Domoic acid is a potent neurotoxin produced by certain marine microalgae that can accumulate in the foodweb, posing a health threat to human seafood consumers and wildlife in coastal regions worldwide. Evidence of climatic regulation of domoic acid in shellfish ...

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 ...

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 ...

Considerations to introduce the Suminoe or Asian oyster Crassostrea ariakensis along the East Coast have raised many questions regarding ecology, economics, and human health. To date, research has focused primarily on the ecological and socioeconomic implications of this initiative, yet ...

In this study, we directly compared two molecular techniques, sandwich hybridization assay (SHA) and quantitative PCR (qPCR), for quantifying laboratory cultures of the ichthyotoxic raphidophyte Heterosigma akashiwo. To maximize comparisons, all experiments entailed raising H. akashiwo in the laboratory, generating ...

Pollution in the marine environment has the potential to negatively impact ecosystem health, including adverse effects on fisheries species. This can occur through direct impacts, food web effects and habitat degradation. Vieques is an island municipality of the Commonwealth of ...

We extend existing oceanographic sampling methodologies to sample an advecting feature of interest using autonomous robotic platforms. GPS-tracked Lagrangian drifters are used to tag and track a water patch of interest with position updates provided periodically to an autonomous underwater ...

The authors regret that, during analyses of various data sets, we inadvertently used TKN (Total Kjeldahl Nitrogen) in place of TN (Total Nitrogen) for the Maumee River tributary. We now present the corrected data from the original Fig. 5 (as ...
