Heat Flow survey offshore Guerrero, southern Mexico (8-G cruise in 2025)
During an oceanographic cruise of the R/V Marcus G. Langseth offshore southern Mexico 148 new marine heat flux data have been acquired in and near the trench of the offshore Guerrero subduction zone. The cruise was organized in the framwork of the project "Oceanic Crust Hydrothermal circulation Offshore Guererro (8-G)". The high-quality heat flux determinations were made on the Cocos plate across plate bending normal faults and adjacent to several seamounts. The heat flux ranged from exceptionally low <30 mW/m² to high heat flow of >300 mW/m², and appears to be indicative of lateral heat redistribution within the basaltic …
