VANC02MV Seismic Reflection/Refraction
Reprocessed 4-channel seismic data offshore the Nicoya Peninsula, Costa Rica margin, acquired in 2002 during the R/V Melville survey VANC02MV
This 2002 Melville cruise, which collected 4-channel MCS data, was part of a multidisciplinary investigation of the thermal state of the subducting lithosphere offshore of the Costa Rica margin. Funded by the U.S. NSF (grants OCE00-01892, OCE00-01941, and OCE00-02031). Its companion cruise, Ticoflux I, was on board the R/V Ewing in 2001. 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 variables affect subduction zone processes, including chemical flux rates. The data were later reprocessed by Jared Kluesner such that the shot spacing and the CDP (or CMP) spacing (half of channel spacing) is forced to be the same (~30 m), resulting in 4 fold data (4 traces per CDP gather). See vanc02mv.README.Kluesner for details.

The data have been processed/modified to a level beyond that of basic quality control (e.g. final processed sonar data, photo-mosaics).
