Thermal conductivity measurements of nearshore sediments in Eckernförde Bay, Baltic Sea aquired during ALKOR cruise AL584@en

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) .2022年11月，在ALKOR科考航次AL584期间，研究人员借助FIELAX GmbH开发的VibroHeat系统采集了近岸沉积物的热导率数据。该系统将振动柱状取样器与搭载22个负温度系数热敏电阻（negative temperature coefficient thermistors, NTCs）的传感器阵列相结合，并配备一根可释放精准调控热脉冲的加热丝。研究人员依据Hartmann与Villinger（2002）提出的反演方法，针对每个热敏电阻计算得到沉积物的原位温度与热导率。
