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.

Monthly composite images of satellite-derived pCO2 for the northern Gulf of Mexico, corresponding to each of the cruises for which observational data were acquired. Black pixels in the images correspond to areas that were masked (e.g., land, clouds), and the dotted lines represent the 45 and 200 m isobaths.

Body

Monthly estimates of ocean surface pCO2 and air-sea flux of CO2 are available from NASA's Carbon Monitoring System.

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.
