Mississippi River Plume Hydrographic Study data from Gulf of Mexico from 1992-04-22 to 1992-05-01 (NCEI Accession 9200235)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 07:51 AM | Dataset Last Updated: March 25, 2026 at 12:00 AM
The accession contains several data sets collected during cruise P921 of the R/V Pelican as part of the Mississippi River Plume Hydrographic Study. Data submitted to NODC in delimited ASCII. One data set contains CTD (Depth, Conductivity, and Temperature data); file(s) also include salinity, dissolved oxygen, backscatter, transmissometer (turbidity), and pressure. This data does not include header information and was not able to be processed in a standard NODC format. Another data set contains Oxygen and Hypoxia data. Data was exported for NODC in delimited ASCII and is in spread sheet format. Third data set contains ADCP (Acoustic Doppler Current Profiler) data collected as part of LATEX (Louisiana-Texas) project. Data was exported for NODC in delimited ASCII. Fourth data set contains Chlorophyll (CHL), Phaeophytin, Salinity, Temperature, and Secchi Disc data. Data was exported for NODC in delimited ASCII and is in spread sheet format. Fifth data set contains Zooplankton data. All the data in this accession is considered INTERIM data; the originator's documentation and file record do not fully correlate with the actual number of files and data types submitted. Final data report was expected to be available by 08/31/93. Principal Investigator: Minerals Management Service/ Louisiana State University Institute: TX-LA Shelf Physical Oceanography Project/ Louisiana State University.
