Surface currents and temperature data from satellite-tracked drifters in the Chukchi and Beaufort Seas from 2011-08-07 to 2014-03-06 (NODC Accession 0126984)

Drifters were deployed from vessels in the Chukchi Sea during the ice-free seasons of 2011-2013. Drifter positions were determined via GPS, and positions were relayed via Iridium communications to on-shore data centers. Drifters were tracked from their release until they a) were picked up at sea for redeployment; b) beached on-shore; or c) died at sea because of battery failure or other causes. Many drifters remained active as sea ice re-formed in the region, and 3 drifters were frozen in the ice and released the following spring. Drifters also recorded Sea Surface Temperature (SST) from 2012 onward. Drifters were of various types (Davis, SVP, and Microstar) and were drogued at various depths (1 m and 10 m).

2011至2013年的无冰季期间，科研人员从科考船向楚科奇海布放了多台海洋漂流浮标。漂流浮标的位置通过全球定位系统（GPS）获取，并经由铱星（Iridium）通信链路将位置数据传输至陆上数据中心。研究人员对浮标自布放起进行全程追踪，直至其出现以下三种终止情况之一：a）在海上被回收以用于重新布放；b）被冲至沿岸滩涂；c）因电池故障或其他故障在海上失效。随着该海域海冰重新形成，仍有大量漂流浮标维持正常运行，另有3台浮标被海冰冻结，于次年春季解冻释放。自2012年起，漂流浮标还同步记录海表温度（Sea Surface Temperature, SST）。本次布放的浮标涵盖Davis、SVP及Microstar三种型号，并分别在1米与10米的深度配置了曳浮装置。
