Summary

Water quality, sediment chemistry and toxicity, benthic ecology, fish tissue toxicity

Parameters

Water column ambient PAR (uE/m^2/s), ammonium (mg/L), chlorophyll a (ug/L), dissolved oxygen (mg/L), pH, particulate nitrogen (mg/L), particulate phosphorus (mg/L), total dissolved nitrogen (mg/L), total dissolved phosphorus (mg/L), dissolved organic nitrogen (mg/L), dissolved organic phosphorus (mg/L), density (kg/m**3), nitrate and nitrite (mg/L), orthophosphate (mg/L), silicate (mg/L), specific conductance (mS/cm at 25C), salinity (ppt), secchi depth (m), temperature (deg. C), total nitrogen (mg/L), total phosphorous (mg/L), total suspended solids, transmissivity (%), water column PAR (mE/sec/m^2), sediment taxa total count, infaunal total count, epifaunal total count, total abundance, biomass, diversity (H'), nekton species and abundance, nekton length (mean and sd), mean silt/clay, mean moisture, mean grab penetration depth, sediment AVS, butyl tin, DDT, metals, non-chlorinated pesticide, PAH, PCB, pesticide, trawl total number of taxa, total abundance, gear type, tissue chemistry analytes

Notes

No longer an operational monitoring program as stated on the website http://www.epa.gov/emap/index.html . Gulf of Mexico sampling occurred 2000-2006. EMAP was the research and design phase of what became the National Aquatic Resource Surveys. Station data obtained here: http://www.epa.gov/emap/html/data/estuary/data/lp91/index.html monitor and assess the status and trends of national ecological resources, ecological status of surface waters, water column parameters, sediment chemistry and toxicity, benthic communities (algae, benthic invertebrates, and fish), demersal fish, and tissue contaminants and other commonly measured field parameters.
