We review marine heat flow data along the Nankai Trough and show that observations >30 km seaward of the deformation front are 20% below conductive predictions (129–94 mW m⁻²) but consistent with the global heat flow average for oceanic crust of the same age (16–28 Ma). Heat flow values ≤30...
[1] We report detailed thermal measurements undertaken during Integrated Ocean Drilling Program (IODP)
Expeditions 315 and 316 along the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) transect
offshore the Kii Peninsula, Japan. Geothermal objectives included determining thermophysical rock properties
of the cored material and characterizing the background thermal regime along this...
At the Costa Rica margin along the Middle America Trench along‐strike variations in heat flow are well
mapped. These variations can be understood in terms of either ventilated fluid flow, where exposed basement
allows fluids to freely advect heat between the crustal aquifer and ocean, or insulated fluid flow where...
