2009 Ice Watch Joint Ocean Ice Study (JOIS) Sea Ice Observation Program

The cruise occurred September 16 to October 15, providing a snapshot of ice conditions at the end of the 2009 melt season and a perspective of the start of freeze-up throughout the Beaufort Sea. Caution should be taken in comparing the 2009 to other years (2006-2008), as the 2009 cruise occurred a month later in the season than previous cruises and we experienced the beginning of the freeze season.

Ship-based sea ice observation data collected along the CCGS Louis S. St. Laurent ship track during the early fall season.

本次科考航次于2009年9月16日至10月15日实施，旨在获取2009年融冰季末期的海冰状况实况快照，以及波弗特海（Beaufort Sea）全域结冰初期的观测视角。将2009年航次与2006-2008年的航次进行对比时需谨慎：2009年航次的作业时间较往年延后了一个月，且本次航次正处于结冰季节的初始阶段。
本数据集为秋季初期沿加拿大海岸警卫队"路易丝·圣罗兰"号（CCGS Louis S. St. Laurent）航行轨迹采集的船基（ship-based）海冰观测数据。
