Abstract:
Thermal conductivity data of nearshore sediments were collected during ALKOR cruise AL584 in November 2022 using the VibroHeat system developed by FIELAX GmbH. This system combines a vibrocorer with a sensor string that contains 22 negative temperature coefficient thermistors (NTCs) and a heating wire over which a defined heat pulse is released. In-situ temperature and thermal conductivity of the sediment are calculated for each thermistor using the inversion method according to Hartmann & Villinger (2002) .
