Toolik River Thermokarst

Active Layer/Permafrost Monitoring:
Lewkowicz, Gooseff, and Godsey deployed 6 ground temperature monitoring stations and a met station from 25 Jun to 26 Jun. All sensors except soil moisture sensors were functional as of 01 Jul. All measurements are being recorded hourly.

Ground temperature monitoring stations are recording temperatures generally at 0, 20, 40, 60, 80, and 100 cm deep. If holes were drilled deeper than 1 m, we are also monitoring temperature at 120, 150, 200, 250, and 300 cm, depending on depth. 6 holes were drilled here, 3 inside of the gulley, 3 outside.
We are also monitoring soil moisture at 0, 20, and 40 cm deep at 3 stations, all of which are outside of the gulley.
The meteorological station is measuring:
- air temperature
- relative humidity
- solar radiation (short wave)
- wind speed & direction
- rainfall
- barometric pressure

Following up on discussions at the ARCSS/TK all scientists meeting, the following naming convention has been proposed:
TOOGT01.xx is the site code for the active gulley thermokarst.

  1. Godsey installed all soil moisture sensors and 1 time-lapse camera on Jul 3.
