In-situ Temperature, Thermal Conductivity and Heat Flow of East Siberian Margin Sediments

Matt O'Regan

Summary of published data used to calculate marine heat flow at sediment coring stations on SWERUS-C3-L2 in 2014. The data file includes A.) Summary table of the calculated in-situ temperature gradient, thermal conductivity and heat flow at each station, B.) A table of the temperature probe number, its normalised depth below the seafloor and the equilibrated in-situ temperature. This data was used to calculate the geothermal gradient using a linear regression, C.) Thermal conductivity measurements on split sediment cores, D.) Water column temperature measurements made by individual temperature sensors as the core barrel was lowered through the water column. The measurements are the raw temperatures, and have not been adjusted to account for absolute offsets between different sensors, E.) Compilation of the normalised temperature data for individual temperature sensors spanning their penetration into the seafloor, equilibration and retrieval.
