Raw data from surface drifters during MERIAN cruise MSM93@en

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.型号为Offshore NOMAD的Southtek铱星GPS漂流浮标（Southtek Iridium GPS drifter，产品详情可访问https://www.southteksl.com/index.php/products/offshore-nomad）被部署于MSM93航次，以阐明表层流场特征。该浮标搭载了长度50厘米的Satis型PVC尾曳（Satis type PVC drogue），预设工作参数为：每10分钟通过GPS获取一次定位坐标，每30分钟通过铱星（Iridium）系统上传一次定位数据。本航次末期（7月28日），为延长浮标续航时长，将定位采集与数据传输的时间间隔调整为每小时一次。最后一次浮标数据传输记录发生于2020年11月18日。本次研究共在弗拉姆海峡（Fram Strait）锋面研究区域部署了31台漂流浮标，编号分别为：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。相关数据集亦可通过国际北极浮标项目（International Arctic Buoy Program）获取，访问链接为https://iabp.apl.uw.edu/IABP_Table.html。
