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.

Project
SWERUS-C3. Swedish – Russian – US Arctic Ocean Investigation of Climate-Cryosphere-Carbon Interactions – The SWERUS-C3 Program – SWERUS-C3 is a multi-disciplinary program with base funding supported from by the Swedish Knut and Alice Wallenberg Foundation (KAW) aiming to investigate the linkages between Climate, Cryosphere (here: sea ice and coastal permafrost) and Carbon release from the sediment, with addition of greenhouse gases (GHG) to the atmosphere.
