Lagrangian drifters in the Southwestern Atlantic Ocean

"55 drifters were deployed along two zonal transects centered at 47 and 47.25ºS on September 8, 2021(Fig. 1). Spacing between the initial deployment positions of the drifters varied between 14 km and 18 km in the continental shelf providing the position every 30 minutes and between 3 km and 6 km over the continental slope with temporal resolution of 10 minutes. The shortest distances between deployment positions correspond to drifters deployed close to the 200 m isobath. The drifters have a 6 m long, 1 m diameter holey sock drogue centered at 15 m depth to track currents at that depth. Each file contains a drifter trajectory in the NetCDF format with the ID number, longitude, latitude and time.
The dataset includes raw positions; For details about the data processing, e.g. the methodology applied to detect the drogue loss, see https://doi.org/10.1016/j.dsr.2024.104319 and https://doi.org/10.1029/2023JC020446
