Data were collected by Texas A&M University (TAMU) in support of LATEX A from 18 March 1993 to 23 September 1993. CTD parameters include temperature, salinity, and sigma-t. Current meter parameters include E/W velocity (U), N/S velocity, temperature, and conductivity. Bottle data includes concentrations of dissolved oxygen, phosphate, nitrite, nitrate, silicate, ammonium, urea, chlorophyll-a, and suspended particulate material. This dataset is available to the public for a wide variety of uses including scientific research and analysis. 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 NCEI Accession 9400149 was revised and a new version of the archival package was published.
