Heat flux data from the Juan de Fuca plate near the Cascadia subduction zone deformation front, 2022 (MGL2208)

In 2022, in-situ measurements of thermal gradient were collected with a 3.5-m violin-style heat flow probe at three sites on the Juan de Fuca plate: around Nubbin Knoll, Diebold Knoll, and the MARGIN site (a basement high, likely a seamount, buried by the Astoria Fan). The 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.
