Temperature profile measurements in the debris-covered headwalls of four thaw slumps in the Tuktoyaktuk Coastlands, Northwest Territories, Canada

Temperature profile measurements in the debris-covered headwalls of four thaw slumps in the Tuktoyaktuk Coastlands, Northwest Territories, Canada, summer 2018 Instruments<br> We used iButton probes (DS1922L; maxim integrated) that were coated with resin.<br> We submerged the probes in an ice bath from 2018-5-31 22:00 - 2018-06-01 11:00. Deployment<br> The iButtons were anchored in hollow, sealed rods. The rods were inserted so that iButtons were located at 5, 20 and 35 cm depth.<br> The rods contained the following iButtons at (05, 20, 35) cm depth [None indicating that there was no probe in the respective slot]:<br> Rod, (probe at 5 cm, probe at 20 cm, probe at 35 cm),<br> 1, (01,02,03)<br> 2, (None,04,None)<br> 3, (None,05,None)<br> 4, (06,07,08)<br> 5, (09,10,11)<br> 6, (None,12,None)<br> 7, (None,13,None)<br> 8, (None,14,None)<br> 9, (16,15,None)<br> 10, (17,18,19) Locations<br> Top Lake:<br> Location: 68.757N, 133.520W<br> 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)<br> Deployment: 2018-06-15 - 2018-08-05 Evan Lake:<br> Location: 68.754N, 133.464W<br> Rods: 9 (central)<br> Deployment: 2018-06-13 - 2018-08-24 Roadside:<br> Location: 69.007N, 133.361W<br> 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)<br> Deployment: 2018-06-27 - 2018-08-21 Timbit Lake:<br> Location: 69.105N, 133.290W<br> Rods: 5 (central)<br> Deployment: 2018-06-15 - lost<br> <br> Data description:<br> 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.
