The deployment was part of the IMPACT project ( http://interreg-maritime.eu/web/impact ) and performed in collaboration with the CMRE-NATO under the framework of a LOGMEC (Long-term glider missions for environmental characterization) experiment.

40 CARTHE-type drifters were deployed in the open sea, in front of the Gulf of La Spezia Gulf (Italy) on May 2, 2019.

CARTHE-type drifters are biodegradable drifters, spanning the first 60cm of the water column (Novelli 2017, 2018, 2020).

The deployment strategy consisted of releasing drifters on a regular grid (about 6km side and 1km step, with some 500m nesting) in a time window of about 2-3 hours.

5 drifters were released in line after passing by the Portovenere Channel, while exiting the Gulf of La Spezia.

5 drifters were collected nearby Toulon (France) on May 17, 2019 and 4 of them were redeployed in the same area on June 24, 2020 (logistical support by University of Toulon).

Each file contains a drifter trajectory in the NetCDF format (ex: 001.nc, 002.nc, etc...).

Trajectories of those drifters that were collected and re-deployed are splitted in different files (ex: 001_a.nc, 001_b.nc).

Nominal drifter transmission rate: 5 minutes. Positions available until June 28, 2019.

The dataset includes raw positions; outliers were removed.
