Physical (Hydrography), chemical (CTD), and biological (Water Quality) processes of the Texas-Louisiana continental shelf, 2012 (NCEI Accession 0162101)

공공데이터포털

Two sets of CTD data were taken during the 2012 surveys of the Louisiana continental shelf—Transect C off Terrebonne Bay and Transect F off Atchafalaya Bay and the 2012 Shelfwide Hypoxia cruise. Hydrographic data were obtained with the LUMCON SeaBird 911+ CTD system and a YSI 6820. Nutrient, pigment, suspended sediment, surface salinity, Secchi depth, Winkler results, and station information data were also acquired.

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 Microsoft Access format, from which NCEI provides a redundant copy in text format.

Two sets of CTD data were taken during the 2011 surveys of the Louisiana continental shelf. Hydrographic data were obtained with the LUMCON SeaBird 911+ CTD system and a YSI 6820. Nutrient, pigment, suspended sediment, surface salinity, Secchi depth, and station information data were also acquired. The physical, biological and chemical data collected are part of a long-term coastal Louisiana dataset. The goal is to understand physical and biological processes that contribute to the causes of hypoxia and use the data to support environmental models for use by resource managers.

Physical and chemical data collected by bottle and CTD in the Gulf of Mexico from R/V Gyre and R/V Pelican, 2004-04 to 2009-07 to help resolve the dominant oceanographic processes that control the timing, duration, and severity of hypoxia of the region (NCEI Accession 0088164)

공공데이터포털

Physical and chemical oceanographic observational data collected by bottle and CTD in the Gulf of Mexico from R/V Gyre and R/V Pelican, April 2004 - July 2009. Data were submitted from the project Mechanisms Controlling Hypoxia on the Louisiana Shelf. This data are part of a comprehensive and multidisciplinary study of the Texas-Louisiana Shelf that included interdisciplinary process cruises and shelf-wide surveys to complement, and provide rates and other parameters necessary for the initiation, control, and skill assessment of a realistic coupled three-dimensional hydrodyamic-biological-geochemical-sediment numerical modeling and statistical (multivariate) modeling elements.

Profiles of temperature, salinity, dissolved oxygen, inorganic nutrients, and other data variables from bottle and CTD casts from multiple platforms in the Gulf of Mexico between 2004 and 2008 compiled as part of the Southeastern Universities Research Association (SURA) testbed Shelf Hypoxia project (NCEI Accession 0073142)

공공데이터포털

Along the Fisheries Oceanography in Coastal Alabama (FOCAL) Transect on the Alabama shelf, a CTD survey was conducted using Seabird SBE 25 Sealogger CTD between 06/04/2019 and 08/02/2019. 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.
