Abstract:
In situ sediment temperature and sediment thermal conductivity measurements were made with the GEOMAR heat flow probe (6m total length) during Expedition MSM57 on board the R/V MARIA S. MERIAN at the Svalbard margin. Two sub-regions were visited: Vestnesa Ridge and Svyatogor Ridge.
A total of eleven deployment sequences were performed. The first deployment was used to defined individual sensor offsets to a reference temperature (data file available in section source data set). Deployment sequence 2 - 8 were conducted around pockmarks on Vestnesa Ridge, and deployment sequence 9 - 11 are at pockmarks across Svyatogor Ridge. During each deployment sequence several individual stations were visited as detailed in Bohrmann et al., (2017) (see datasets listed in this publication series below).
From the individual measured temperature records, thermal gradients and in situ thermal conductivity values are derived using the technique described in Villinger and Davis (1986). We report here our initial results as well.
Initial results and further details of the deployments can be found in the cruise report by Bohrmann et al. (2017).
