Multiple Stressors at the Land-Sea Interface: Cyanotoxins at the Land-Sea Interface in the Southern California Bight
Blooms of toxic cyanobacteria in freshwater ecosystems have received considerable attention in recent years, but their occurrence and potential importance at the land-sea interface has not been widely recognized. Here we present the results of a survey of discrete samples conducted in more than fifty brackish water sites along the ...
Multivariable statistical regression models of the areal extent of hypoxia over the Texas-Louisiana continental shelf
Observations of the areal extent of seasonal hypoxia over the TexasLouisiana continental shelf from 1985 to 2010 are correlated with a variety of physical and biogeochemical forcing mechanisms. Significant correlation is found between hypoxic area and both nitrogen load (r2 = 0.24) and eastwest wind speed (r2 = 0.16). There ...
Mussel Site Description and Sampling Procedures for Washington State
National Status and Trends (NS&T) Mussel Watch Program provides status of and temporal trends of coastal contaminant conditions. Bivalve tissues are analyzed for a suite of about 500 legacy and emerging chemicals of concern. In addition, bivalve tissues are assessed for histopathology and gonadal index. The Program’s data, metadata and ...
Mussel Watch sampling procedures and site descriptions for Oregon State
National Status and Trends (NS&T) Mussel Watch Program provides status of and temporal trends of coastal contaminant conditions. Bivalve tissues are analyzed for a suite of about 600 legacy and emerging chemicals of concern. In addition, bivalve tissues are assessed for histopathology and gonadal index. The Program’s data, metadata and ...
N and P as ultimate and proximate limiting nutrients in the northern Gulf of Mexico: Implications for hypoxia reduction strategies
The occurrence of hypoxia in coastal oceans is a long-standing and growing problem worldwide and is clearly linked to anthropogenic nutrient inputs. While the need for reducing anthropogenic nutrient loads is generally accepted, it is costly and thus requires scientifically sound nutrient-reduction strategies. Issues under debate include the relative importance ...
Narragansett Bay hypoxic event characteristics based on fixed-site monitoring network time series: Intermittency, geographic distribution, spatial synchronicity, and interannual variability
Low dissolved oxygen events were characterized in Narragansett Bay (NB), a moderate-size (370 km2) temperate estuary with a complex passage/embayment geometry, using time series from 2001 to 2006 at nine fixed-site monitoring stations. Metrics for event intensity and severity were the event-mean deficit relative to a threshold (mg O2 l?1) ...
National Centers for Coastal Ocean Science (NCCOS) long-term monitoring: Regional Ecological Assessments and National Benthic Inventory (NCEI Accession 0202842)
The NCCOS Regional Ecological Assessments (REA) and NOAA National Benthic Inventory (NBI) include observations of water quality, sediment quality, fish and shellfish tissue chemical contaminants, and benthic infaunal abundance obtained from studies conducted since 1991 by NOAA and partnering institutions in estuarine and coastal-ocean areas of the United States. Measured ...
