Data collected measured depth (m), salinity (PSU), temperature (ITS-90, deg C), oxygen (% Saturation), oxygen (mg/L), pH (pH), specific conductance (µS/cm), beam attenuation (1/m), beam transmission (%), density (kg/m3), conductivity (µS/cm), PAR (µmol m-1 s-1), fluorescence (mg/m3), and fluorescence (mg/m3). Data was collected on 2019-06-04, 2019-06-28, 2019-07-02, 2019-07-05, 2019-07-09, 2019-07-16, 2019-07-19, 2019-07-30, and 2019-08-02 during the summer of 2019. The objective of this ongoing research is to identify the influence of fluvial water and its suspended particulate matter, freshwater influx and nutrient load on coastal regions including the ecosystem and its susceptibility to hypoxia and low saline events. This particular study aims to understand the nature of buoyant freshwater plumes in shallow micro-tidal environments. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0206155 Preview graphic PNG 0206155 NCEI ACCESSION NUMBER 2019-09-09 publication CONDUCTIVITY DISSOLVED OXYGEN FLUORESCENCE pH SALINITY WATER DENSITY WATER TEMPERATURE theme NODC DATA TYPES THESAURUS CTD instrument NODC INSTRUMENT TYPES THESAURUS in situ theme NODC OBSERVATION TYPES THESAURUS Dauphin Island Sea Lab dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS Dauphin Island Sea Lab dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Coastal Waters of Alabama Coastal Waters of Gulf of Mexico Gulf of Mexico place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication Fisheries Oceanography in Coastal Alabama (FOCAL) project Provider Project Names EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > OXYGEN EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > PH EARTH SCIENCE > OCEANS > OCEAN OPTICS > FLUORESCENCE EARTH SCIENCE > OCEANS > OCEAN TEMPERATURE > WATER TEMPERATURE EARTH SCIENCE > OCEANS > SALINITY/DENSITY > CONDUCTIVITY EARTH SCIENCE > OCEANS > SALINITY/DENSITY > DENSITY EARTH SCIENCE > OCEANS > SALINITY/DENSITY > SALINITY theme Global Change Master Directory (GCMD) Science Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
