Abstract

A cluster of 20 CARTHE-type drifters were deployed in the open sea area in front of Livorno (Italy) on October 8, 2020.

The deployment was part of the DDR20- "Drifter demonstration and Research 2020" experiment performed in collaboration with the CMRE-NATO and Consorzio LaMMA, and supported by many EU projects, such as SICOMAR plus, JERICO-S3, SINAPSI, and IMPACT.

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 3km side and 500m step) in a time window of about 2 hours.

5 drifters heading south were collected on October 10, 2020 and re-deployed, on the same day, approx. 2.5 nm to the north of the initial deployment area.

3 stranded drifters were redeployed on November 11, 2020 in the open sea area in front of the La Spezia Gulf.

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: 10 minutes. Positions available until January 23, 2021.

The dataset includes raw positions; outliers were removed.
