GLAD experiment CODE-style drifter trajectories (low-pass filtered, 15 minute interval records), northern Gulf of Mexico near DeSoto Canyon, July-October 2012

297 trajectories from near-surface CODE-type ocean drifters (drogued at a depth of one meter) tracked in real-time using SPOT GPS units, launched in the northern Gulf of Mexico near DeSoto Canyon in July 2012 as part of the CARTHE Grand Lagrangian Deployment (GLAD) experiment. Most of these drifters were launched as triplets (separated by roughly 100 meters at launch) in an attempt to measure multi-scale near surface dispersion. Positions are low-pass filtered (one hour cutoff period) and interpolated to uniform 15 minute intervals starting on whole hours over the period July 20 through October 22, 2012. No temperature or salinity sensors were attached to these drifters. This dataset was created by the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE). This research was made possible by a grant from BP/The Gulf of Mexico Research Initiative.
