Title: CTD cast data collected during R/V Atlantis cruise AT18-02 in the Northern Gulf of Mexico from 2010-11-26 to 2010-12-02.

Abstract: This dataset includes conductivity, temperature, and depth (CTD) data from casts performed in the northern Gulf of Mexico during R/V Atlantis cruise (AT18-02) from November 26 to December 02, 2010. The cruise departed from Galveston, Texas and ended in Gulfport, Mississippi.
