Over the past two decades China has become the largest global consumer of fertilizers, which has enhanced river nutrient fluxes and caused eutrophication and hypoxia in the Yangtze (Changjiang) large river delta-front estuary (LDE). In this study, we utilized plant ...

There is growing awareness that fluctuations in larval flux (connectivity) depress the long-run growth of marine metapopulations, but by how much is unclear. Here, we explore how reproductive schedule and larval behavior affect how much connectivity fluctuations depress growth. We ...

The goal of this pilot project was to assess the presence of a number of commonly prescribed human use pharmaceuticals in three coastal areas of the U.S. Water samples were collected in conjunction with three NOAA monitoring/research projects to assess ...

Hydrographic and chemical data were collected for a week in late July between 1994-1997 in order to survey the coastal hypoxia on Louisiana continental shelf. Nutrient, pigment, suspended sediment and station information data were also acquired. Data files provided in ...

Hypoxia (< 2 mg O2 l? 1) is a major global water quality and fisheries management issue in coastal ecosystems. Although the impact of hypoxia on benthic communities has been intensively studied, less is known about hypoxia's effect on pelagic ...

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 ...

In 1972, J. Woodland Hastings and colleagues predicted the existence of a proton selective channel (HV1) that opens in response to depolarizing voltage across the vacuole membrane of bioluminescent dinoflagellates and conducts protons into specialized luminescence compartments (scintillons), thereby causing ...

Harmful algal blooms caused by Karenia brevis result in large fish kills, human respiratory irritation, and shellfishing closures in affected areas. Most previous work on bloom formation in the Gulf of Mexico has focused on the west coast of Florida ...

The ecology of the Chesapeake Bay and its watershed is deeply intertwined in the history, culture, and economy of the communities in this region, and provides people with valuable ecosystem services. Due to the connectivity between communities and the environment, ...

Mesophotic hard corals (MHC) are increasingly threatened by a growing number of anthropogenic stressors, including impacts from fishing, land-based sources of pollution, and ocean acidification. However, little is known about their geographic distributions (particularly around the Pacific islands) because it ...
