GLODAPv2_316N19831113: CTD and Bottle Measurements from the KNORR Cruise

NODC Accession 0117698 contains discrete sample and profile data from the KNORR research vessel's cruise GLODAPv2_316N19831113. Measurements include dissolved oxygen, nitrate, nitrite, phosphate, silicate, salinity, and water temperature, collected using CTD and bottle instruments. Arnold Gordon of Lamont-Doherty Earth Observatory collected these data in the Indian Ocean and South Atlantic Ocean between November 13 and December 10, 1983.

Use Cases

• Analyzing nutrient distributions (nitrate, phosphate, silicate) to study marine biogeochemical cycles.
• Calculating ocean density and stratification based on concurrent salinity and temperature (theta) profiles.
• Assessing dissolved oxygen levels for studies of ocean ventilation and biological respiration.
• Validating ocean carbon cycle models using a suite of co-located chemical and physical measurements.
• Studying water column structure through hydrostatic pressure readings from CTD profiles.

Strengths

• Data includes a specific suite of nine co-located chemical and physical variables, enabling multivariate analysis.
• Coverage spans two major ocean basins (Indian Ocean and South Atlantic Ocean) over a defined 28-day period.
• Data is part of the GLODAPv2 project, a recognized international ocean carbon data synthesis effort.

Limitations

• Column names and exact data structure are not provided in any source description.
• Sources conflict on the 'last updated' metadata, with one listing 2026 and another listing 1983.
• Dataset size, row count, and license information are not available from any platform.
