Abstract:

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.

Purpose:

Triads of CODE style drifters (initially separated by roughly 100 meteres) were launched nearly simultaneously to measure near-surface relative dispersion over scales ranging from 100 meters to 100 km.

Positions reported by the SPOT handheld GPS units inside each drifter were nominally accurate to within seven meters. Occasionally, position errors much larger than this nominal value are found. These may be due to errors in GPS baselines (due to poor satellite reception), data dropout, and, in some cases, drifters that were picked up by small boats. Each drifter record ends when the drifter was known to be picked up by a boat, when the signal was lost for more than 24 hours, or when the drifter traveled more than 80 km in a 12 hours period (implying a mean speed of 1.85 m/sec over 12 hours). For each record, positions that imply an instantaneous drifter speed greater than 3 m/sec were deleted. Also, positions that imply the drifter track rotated through more than 360 compass degrees within three hours were deleted. Next, outliers were identified as positions that were more than 100 meters away from estimated positions at the same times interpolated from a set of both past and future positions. These outliers were deleted. All valid positions were then interpolated to uniform, five-minute time intervals using spline interpolation. These five-minute records were used to compute finite difference estimates of u (east-west) and v (north-south) velocities. Finally, the five-minute position and velocity records were filtered using a Butterworth fourth-order low-pass filter with a one hour period cutoff. These low-pass filtered records were then interpolated to uniform 15-minute intervals beginning on whole hours. Crude estimates of position error are also provided for each position in the final 15-minute interval records. The error was set to 10 meters (a nominal value) for positions recorded at times for which there were no gaps in the five-minute raw data records over the previous hour. The error was increased according to the ratio of the average sample time interval for the previous 12 raw data positions to the nominal sample interval of 5 minutes, multiplied by the 10 meter nominal error value. Velocity errors were computed by dividing the sum of two consecutive position errors by the corresponding time interval.|CODE II drifter body with SPOT Satellite GPS Messenger (orange).|Raw drifter positions were low-pass filtered (one hour cutoff period) and interpolated to uniform 15 minute intervals starting on whole hours.||
