Time-series of temperatures were measured adjacent to the met station at Toolik Main (TM, nine depths) using self-contained temperature loggers on taut-line moorings with a subsurface float 1 m below the air-water. Oregon Environmental Instruments (OEI) Model 9311 temperature loggers with an accuracy and resolution of 0.0058C and time constant of 5 s were used at TM. Recording was done at 10-s intervals. The units were calibrated before and after deployment against a platinum resistance thermometer with an accuracy of 0.00068C. Column description, including measurement depth (in meters) given in line 1 of the data file.
