Data & Publications

Great Lakes Mussel Watch: Assessment of Contaminants of Emerging Concern

The current report summarizes Great Lakes mussel tissue contaminants of emerging concern (CEC) data obtained between 2013-2015. The study design informs MWP management, stakeholders and general public about the frequency of occurrence, and the magnitude of CECs in mussels. We ...

Gulf of Mexico Hypoxia: Exploring Increasing Sensitivity to Nitrogen Loads

Hypoxia is a critical issue in the Gulf of Mexico that has challenged management efforts in recent years by an increase in hypoxia sensitivity to nitrogen loads. Several mechanisms have been proposed to explain the recent increase in sensitivity. Two ...

Historical Nitrogen and Phosphorus Loadings to the Northern Gulf of Mexico

The purpose of this analysis is to examine the historical fluxes of N and P to the northern Gulf of Mexico and discuss the implications that this may have for primary productivity, hypoxia and management strategies ...

Historical trends of hypoxia in Changjiang River estuary: Applications of chemical biomarkers and microfossils

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 ...

Human Use Pharmaceuticals in the Estuarine Environments: A Survey in the Chesapeake and Biscayne Bays

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 water parameters collected by CTD and other instruments from the Pelican and the Tommy Munro in coastal waters of Louisiana from 1994-07-24 to 1997-07-29 (NCEI Accession 0164298)

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 ...

Interannual Variation in Stratification over the Texas–Louisiana Continental Shelf and Effects on Seasonal Hypoxia

A numerical dye is used to track freshwater released in May and June from the Mississippi and Atchafalaya rivers using a hydrodynamic model. These months are chosen because discharge and nutrient load in May and June is significantly correlated with ...

Landscape-Level Variation in Disease Susceptibility Related to Shallow-Water Hypoxia

Diel-cycling hypoxia is widespread in shallow portions of estuaries and lagoons, especially in systems with high nutrient loads resulting from human activities. Far less is known about the effects of this form of hypoxia than deeper-water seasonal or persistent low ...

Linking molecular microbial ecology to geochemistry in a coastal hypoxic zone

Multiple environmental mechanisms have been proposed to control bottom water hypoxia (<2 mg O2 L?1) in the northern Gulf of Mexico Louisiana shelf. Near-bottom hypoxia has been attributed to a direct consumption of oxygen through benthic microbial respiration and a ...
