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编号为53536至53538的浮标于2007年8月23日，在东经211°/212°、北纬78.5°附近以相互间呈三角形布局的方式完成部署。其位置数据的信号传输持续至2008年夏秋季。该组浮标先向北漂移至北纬80°以北的最北边界，随后向东、向南移动，抵达东经231°的最东边界，之后继续向南并转向西，最终停留在北纬74°至72°区间，相较部署位置显著偏南。其中编号53536的浮标绕行一圈并向西移动，最终几乎回到初始经度，但纬度大幅偏南。ARGOS编号为74353至74364的浮标作为SEDNA科考项目的组成部分，于2007年3月24日在东经212°、北纬73°附近以双层嵌套六边形布局完成部署。该组浮标先向西北漂移，随后转向北，最终向东北移动。多数浮标在转向向南之前即停止信号传输，但编号74360与74361的浮标转向向南，其中前者于2009年6月几乎返回了部署点位。编号74363是唯一一台持续信号传输至2009年的浮标，其始终沿东北轨迹移动，未向南绕行。编号74358是首个于2007年6月停止信号传输的浮标；编号74355、74359、74362与74364的浮标于2007年9月/10月停止信号传输；其余浮标的信号则于2008年6月至10月间中断。
