This data package includes data from GRIIDC UDIs R1.x137.131:0002, R1.x137.131:0003, and R1.x137.131:0004. It contains data collected during the Gulf of Mexico Integrated Spill Response Consortium (GISR) G03 cruise held 28 November to 20 December 2012 aboard the R/V Pelican (Cruise designator PE-1315 ). The Principal Investigator was Dr. James R. Ledwell from Woods Hole Oceanographic Institution (WHOI). 

The purpose of this cruise was to sample for chemical tracer released on the Gulf of Mexico Integrated Spill Response Consortium (GISR) G02 Cruise in July-August 2012.
