Instrument Request for ITOPNC (201851)


Long Name: Investigating Thickness of Peridotites in New Caledonia (formerly CaNappe)


How are ophiolites emplaced, and how does this relate to subduction initiation? This is a question that may drive an ICDP-IODP proposal in 2019 to drill in and around New Caledonia. We will collect passive seismic data near road RP3 between Noumea and Yate in southeastern New Caledonia, to constrain the depth to the base of the ophiolite. We will focus on the region from the southwest edge of ultramafic rocks to Lac de Yate, to complete a transect between two permanent broadband sites. We will deploy 12 broadband instruments for up to one year. Surface waves and converted/reflected waves from the basal interface will be analysed. Energy sources will be natural earthquakes or/and ambient noise and possibly active-source blasts (mines, ships, etc.). The data set will be used to facilitate an international collaboration between European, US, and southwest Pacific scientists and will be the basis for choosing future drilling sites.
