Examples of freeze-up stages in the Grayling study area. Landsat images are displayed as color composites (R: SWIR, G: NIR, B: green), where water appears dark blue and snow/ice appears light blue.

Body

Estimates of river ice breakup and freeze-up stages along selected reaches of the Yukon and Tanana Rivers in the Yukon River Basin in interior Alaska from 1972-2016 are now available from ABoVE.

USArray measurement sites in Alaska. Sites are labeled with site ID and maximum measurement depth and color-coded by mean annual ground temperature (MAGT in degrees C) of the deepest sensor measurements. Data are omitted for sites disrupted by bears.

Body

Soil temperature data were collected at Alaskan USArray seismic monitoring sites from 2016-2018.
