GPS Drifting Buoys Deployed in Beaufort Sea 2007 (JWACS07)

Buoys with ARGOS ID's 53536 thru 53538 were deployed in a triangular configuration relative to one another on August 23, 2007 around 211/212 deg East and 78.5 deg North. They broadcasted position data into Summer/Fall 2008. The group drifted North to a maximum extent of just over 80 deg North, moved East and South to the maximum Eastern Extent of 231 degrees and continues south and then West ending 74 to 72 degrees North, considerably farther south than the deployment position. ID#53536 loops around and moves westward to end almost back to the same longitude that it began but well South. Buoys with ARGOS ID's 74353 thru 74364 were deployed as part of SEDNA campaign March 24, 2007 in two hexagonal patterns, one inside the other ~ 212 degrees East, 73 degrees North. They drifted North West, then North and finally North-East. Most buoys fail before turning South but buoys ID#74360 and 74361 turn South with the former almost coming back to the deployment point in June 2009. ID#74363 is the only other buoy to continue to report into 2009 and it remains on a North-East Track and does not loop South. ID# 74358 is the first to fail in June 2007. ID's 74355, 74359, 74362 and 74364 fail in Sept/Oct. 2007. The rest are lost between Jun 2008 and October 2008.ARGOS标识（ARGOS ID）为53536至53538的浮标于2007年8月23日左右，在东经211°/212°、北纬78.5°的海域以三角形相对布局完成部署，其位置数据广播工作持续至2008年夏秋季节。该组浮标先向北漂移，最大纬度可达北纬80°以上；随后向东、向南移动，抵达东经231°的最东端位置；之后继续向南并转向西，最终停留在北纬74°至72°区间，较初始部署位置显著偏南。其中浮标ID#53536完成绕圈后向西移动，最终几乎回到初始经度位置，但纬度已大幅偏南。 ARGOS标识为74353至74364的浮标作为SEDNA科考任务（SEDNA campaign）的一部分，于2007年3月24日完成部署，采用内外嵌套的双六边形布局，部署位置约为东经212°、北纬73°。这些浮标的漂移轨迹依次为：先向西北方向移动，随后向北，最终转向东北。大部分浮标在转向南向移动前就停止了工作，但浮标ID#74360与ID#74361完成了南向转向，其中ID#74360甚至在2009年6月几乎回到了初始部署点。仅浮标ID#74363持续上报数据至2009年，其始终沿东北向轨迹移动，未向南折返。浮标ID#74358是首个于2007年6月停止工作的浮标；浮标ID#74355、74359、74362及74364于2007年9月/10月间停止工作；其余浮标则在2008年6月至2008年10月期间失联。
