Submesoscale Processes and Lagrangian Analysis on the Shelf (SPLASH) surface drifter’s interpolated to 5-minute intervals data in the Louisiana Bight from 2017-04-19 to 2017-06-08

Several hundred Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE) surface drifters were released during the Submesoscale Processes and Lagrangian Analysis on the Shelf (SPLASH) experiment in the Louisiana Bight from 2017-04-19 to 2017-06-08. The drifters were drogued at 0.5 m depth and reported their positions in real-time using SPOT GPS units nominally every 5 minutes for up to about 5 months. Some of the drifters were equipped with temperature and/or salinity sensors. This dataset contains the quality-controlled data, where positions suggesting excessive velocities (> 2.62 m/s) or accelerations (> 0.01 m/s^2) were removed. The positions were then interpolated using a Hermitian cubic algorithm to uniform 5-minute intervals. However, gaps exceeding three hours were not filled. Where available, temperature and salinity data from HOBO sensors were appended to the trajectories. A companion dataset with the raw data is available under GRIIDC Unique Dataset Identifiers (UDI) R4.x265.238:0001 (DOI: 10.7266/n7-wgt0-kw56).
