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.

2001年的Ewing巡航是针对哥斯达黎加海缘海底地壳热状态的跨学科研究项目的一部分。其姊妹航次Ticoflux II于2002年在R/V Melville号上执行。此次航次的目的是确定这些区域海底地壳的相对热状态，以及与之相关的热量和流体通量，这些通量负责形成海底地壳的热状态，并探讨这些变量如何影响板块俯冲过程，包括化学通量速率。该项目由NSF资助，资助编号分别为OCE00-01892、OCD00-01944、OCE00-02031。
