Temperature profile measurements in the debris-covered headwalls of four thaw slumps in the Tuktoyaktuk Coastlands, Northwest Territories, Canada, summer 2018 Instruments We used iButton probes (DS1922L; maxim integrated) that were coated with resin. We submerged the probes in an ice bath from 2018-5-31 22:00 - 2018-06-01 11:00. Deployment The iButtons were anchored in hollow, sealed rods. The rods were inserted so that iButtons were located at 5, 20 and 35 cm depth. The rods contained the following iButtons at (05, 20, 35) cm depth [None indicating that there was no probe in the respective slot]: Rod, (probe at 5 cm, probe at 20 cm, probe at 35 cm), 1, (01,02,03) 2, (None,04,None) 3, (None,05,None) 4, (06,07,08) 5, (09,10,11) 6, (None,12,None) 7, (None,13,None) 8, (None,14,None) 9, (16,15,None) 10, (17,18,19) Locations Top Lake: Location: 68.757N, 133.520W Rods: 4 (central), 7 (23 cm above central rod in dip direction), 1 (25 cm from central rod in strike direction [west]), 6 (23 cm below central rod in dip direction), 20 (10 m from headwall; slump floor) Deployment: 2018-06-15 - 2018-08-05 Evan Lake: Location: 68.754N, 133.464W Rods: 9 (central) Deployment: 2018-06-13 - 2018-08-24 Roadside: Location: 69.007N, 133.361W Rods: 10 (central), 2 (20 cm above central rod in dip direction), 8 (20 cm from central rod in strike direction [west]), 3 (20 cm below central rod in dip direction) Deployment: 2018-06-27 - 2018-08-21 Timbit Lake: Location: 69.105N, 133.290W Rods: 5 (central) Deployment: 2018-06-15 - lost Data description: Each XX.txt file contains the native output of the iButton software by maxim integrated for probe XX. A calibration offset can be estimated from the average temperature recorded during the ice-bath calibration period.
