Imnavait Watershed Thaw Depth Survey Summary for 2003 to 2023, Arctic LTER, Toolik Research Station, Alaska.

Thaw depth was measured using a steel probe in the Imnavait Creek watershed, near Toolik Lake, Alaska. The thaw grid includes measurements made from the valley bottom (on both sides of the stream), up the hillslope. The thaw grid is near Imnavait water tracks 7 and 8, and measurements have been made from the 2003 season until present. At least two surveys are conducted each summer, on 2 July and on 11 August (plus or minus a couple of days on either side of those dates).

本数据集针对阿拉斯加州图利克湖（Toolik Lake）附近的伊姆纳夫特溪（Imnavait Creek）流域开展解冻深度测量，测量工具为钢制探杆。该解冻深度测量网格的覆盖范围从河谷底部（溪流两侧）延伸至山坡地带，且位于伊姆纳夫特7号与8号水迹带附近。测量工作自2003年野外季起持续开展至今，每年夏季至少完成两次野外调查，分别定于7月2日与8月11日前后（日期允许上下浮动数天）。
