Title:
Heat flux data from the MARGIN seep site, 2022 (MGL2208)
Abstract:
The MARGIN site is at a buried basement high (likely a buried seamount) offshore Oregon, ~25 km seaward of the Cascadia subduction zone deformation front. The buried basement high rises ~1300 m above the surrounding basaltic basement. The MARGIN basement high was first identified on the north-south-trending MARGIN transect, collected as part of the Juan de Fuca Ridge-to-Trench project; that seismic transect crossed the flank of the MARGIN basement high. Subsequently, the east-west-trending Line PD11 collected as part of the MGL2104 CASIE21 project conducted in 2021 crossed a higher and more substantial portion of the MARGIN basement high. In 2022, in-situ measurements of thermal gradient were collected crossing and around the MARGIN basement high using a 3.5-m violin-style heat flow probe. This multi-penetration heat flow probe was loaned from the U.S. Marine Heat Flow Capability. The thermistor string houses 11 thermistors. The in-situ thermal gradient is combined with an assumed thermal conductivity versus depth trend to determine the heat flow. The data was processed using SlugHeat (https://marine-heatflow.ceoas.oregonstate.edu/software/). The data file is in ASCII tab-separated format, with column headers. Funding was provided by National Science Foundation awards OCE19-24331, OCE20-34872, and OCE20-34896.
