Processed multichannel seismic data offshore the Costa Rica margin, acquired during the R/V Maurice Ewing survey EW0104 (2001)

This 2001 Ewing cruise was part of a multidisciplinary investigation of the thermal state of the subducting lithosphere offshore of the Costa Rica margin. Its companion cruise, Ticoflux II, was on board the R/V Melville in 2002. The goals were to determine the comparative thermal state of the subducting lithosphere in these regions, the associated heat and fluid fluxes responsible for the subducting slab thermal states, and how these variable affect subduction zone processes, including chemical flux rates.
