This folder contains data collected during the GISR G03 cruise held 28 November to 20 December 2012
aboard the R/V Pelican (Cruise designator 13PE15). The Principal Investigator was Dr. James R. Ledwell (WHOI).
The purpose of the cruise was to sample for chemical tracer released on the GISR G02 Cruise in July-August 2012.

These data will be transmitted to the Gulf of Mexico Research Initiative Information and Data Cooperative (GRIIDC) and
ultimately archived at the National Ocean and Atmospheric Administration's National Ocean Data Center (NOAA/NODC).

This folder contains the following items.
