This metadata template is designed to describe a seismic dataset. A dataset is a logical grouping of files such as one or more seismic lines, a 3D data volume or a set of seismic velocity files. A dataset collection may also be determined by processing level,
geographic bounds, or other parameters. The data provider or metadata author may determine the best way to aggregate the information.
SeismicMetadata: the root metadata element.

This was a joint UT and Lamont-Doherty Earth Observatory program collecting a series of MCS lines in the Bransfield Strait, across the South Shetland Trench and farther south along the Antarctic margin. UTIG was responsible for the Bransfield Strait and South Shetland Trench data.
Additional lines collected farther south along the margin were the responsibility of Lamont-Doherty Earth Observatory. |
