Abstract:

This GISR G05 cruise (July-August 2013) was designed to measure the concentration of a chemical tracer released a year ago on the GISR G02 Cruise (July-August 2012). The dataset includes measurements from the shipboard underway system and cruise documentation.

Purpose:

This is ancillary data that gives additional information about the physical state of the ocean and atmosphere during the cruise.
