Pacific Data Assessment

This page contains detailed information on the QA/QC procedures used to examine the quality of the Pacific data. These procedures can be used to infer the internal consistency of the basin-wide dataset and may be used to infer an offset with a given parameter on a particular cruise. To see a summary of the findings and any proposed adjustments listed by cruise please refer to the Adjustments Page.

Crossover Locations

The primary means of evaluating the internal consistency of the data was to compare deep water concentrations in locations where two or more cruises intersect or overlap. Crossover locations are given below:
