The Collisional Orogeny in the Scandinavian Caledonides (COSC) drilling project focuses on understanding orogenic processes in western Scandinavia (Lorenz et al., 2015). The project presents an opportunity to study how heat transport affects brittle and ductile deformation in the lithosphere. Here, we present results of measurements with an optical scanning instrument (Thermal Conductivity Scanner; TCS) on about 100 core samples retrieved from the borehole COSC-1. Details about the measurement procedures are given in the following sections. For a list of core sample IDs that are assigned with International Generic Sample Numbers (IGSN, see Conze et al., 2017), please see the associated data description file. The sample IDs give the identifier of the borehole (5054_1_a) and then core# and section# (e.g., 5054_1_A_7_1_WR_4-24, where core# is 7 and section# is 1). Further information (e.g., elevation, depth, sample photos, etc.) about each sample can be found on the GFZ Data Services repository. Individual sample pages can be accessed directly using the IGSN, for example: https://igsn.org/ICDP5054EX71601 (or via the links in the Related Works section of this DOI landing page). The TCS measurements were made at the Fraunhofer Institute, Bochum, formerly known as the International Geothermal Centre, Bochum, on a Lippmann Geophysical Instruments TCSCAN, hardware version 2 (https://www.l-gm.de/en/en_tcs.html). The procedure used for the measurements is described in the user manual, which can be found at https://www.tcscan.de.
