Raw data from surface drifters during MERIAN cruise MSM93

Southtek Iridium GPS drifters of type Offshore NOMAD (https://www.southteksl.com/index.php/products/offshore-nomad) were deployed on MSM93 to elucidate the surface flows. The drifters had a 50cm long PVC drogue of type Satis. They were programmed to determine their position with GPS once every 10 minutes and to transmit those positions via Iridium once every 30 minutes. Towards the end of the cruise (on July 28) those intervals were lengthened to hourly position acquisition and transmission in order to increase their life-time. The last transmission from a drifter occurred on November 18, 2020. The following 31 drifters were deployed in the Fram Strait frontal study area: LCE00506, LCE00508, LCE00509, LCE00510, LCE00511, LCE00512, LCE00513, LCE00514, LCE00515, LCE00516, LCE00517, LCE00518, LCE00519, LCE00521, LCE00522, LCE00523, LCE00524, LCE00525, LCE00526, LCE00528, LCE00529, LCE00530, LCE00531, LCE00532, LCE00534, LCE00535, LCE00536, LCE00537, LCE00538, LCE00539, LCE00540. The data is also available through the International Arctic Buoy Program https://iabp.apl.uw.edu/IABP_Table.html.
