Processed multichannel seismic data in the Sandino forearc basin, offshore Costa Rica, Nicaragua, Honduras and El Salvador, acquired during R/V Maurice Ewing expedition EW0412 (2004)

The EW0412 expedition was part of NicStrat, a project designed to image Neogene depositional sequences indicative of sea-level change and stratal geometries that may reflect local tectonic history. The primary objectives were 1) to test the hypothesis that the stratigraphic records of eustatic and tectonic processes can be identified and distinguished on high-resolution MCS data from the Sandino forearc basin, on the Pacific margin of Nicaragua; and 2) to evaluate the record of tectonic events in the form of local unconformities and/or tectonically controlled variations in the geometries and stacking patterns of regional eustatic sequences. Funding was provided by NSF grant OCE-0241179.
