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.

本次2001年的Ewing巡航是针对哥斯达黎加海缘之下地壳热状态的多学科调查的一部分。其伴随巡航Ticoflux II于2002年在R/V Melville号上进行。其旨在确定这些区域下地壳的热状态比较，以及导致下地壳热状态的相应热流和流体通量，并探讨这些变量如何影响俯冲带过程，包括化学通量速率。该研究由NSF资助，项目编号为OCE00-01892、OCD00-01944和OCE00-02031。
