Antarctic Seismic Data Library System (SDLS)

About SDLS

The Antarctic Seismic Data Library System (SDLS) works under the auspices of Scientific Committee on Antarctic Research (SCAR) and the Antarctic Treaty (ATCM XVI-12) to provide open access to all multichannel seismic-reflection data collected south of 60° S to study the structure of the earth's crust of Antarctica. This page provides links to answers for many common questions about the SDLS, and how the library system can be used by all researchers.

The SDLS is under the mandates of the Antarctic Treaty System, and as such, all institutions that collect MCS data in Antarctica are requested to submit their MCS data to the SDLS. The formal guidelines that govern the SDLS are outlined in general in Antarctic Treaty Consultative Meeting Resolution XVI-12, and in particular in SCAR Report No 9.

The main SDLS database is currently hosted by OGS, Italy. They maintain a website that allows searching, viewing and downloading for existing and available multi-channel seismic data. Free registration is required for downloading data. Copies of the data area also hosted at the SDLS library branches in different countries.

Lamont SDLS branch

The SCAR Seismic Data Library System (SDLS) has branches worldwide. The US branches are hosted by USGS (Menlo Park, CA) and Lamont-Doherty Earth Observatory (Palisades, NY).
