Description

This dataset contains discrete measurements of temperature and dissolved oxygen at Dorado Outcrop during R/V Atlantis cruise AT26-24. It also includes the time, latitude, and longitude of the Alvin dives that collected the measurements.

Methods & Sampling

Dataset acquisition description

Temperature measurements were made with the thermal couple on board the HOV Alvin. The dissolved oxygen concentrations were measured with an Aanderra optode.

The Alvin dives were conducted off the west coast of Costa Rica in the Pacific Ocean at Dorado Outcrop during the R/V Atlantis cruise AT26-24. For more information about operations of this cruise see the cruise pages which contain links to cruise reports (AT26-24)

Data Processing Description

Dataset Processing Description

The data have not been processed further.

BCO-DMO Processing Notes:

* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* added lat/lon of Alvin dives as listed in the Alvin Dive Log
