Publicly Released 'SMAART' Data Sets, available to the Geophysical
( In cooperation with TNO and DELPHI )
is an elastic dataset released in November 2000, that contains realistic free
surface and internal multiples over a structure that is relatively easy to
Sigsbee 2A is an constant density acoustic dataset
released in September 2001, that does not contain free surface multiples and
almost no internal multiples due to very low contrast water bottom, but it is
over a sub-salt structure that is difficult to image.
2B - Free Surface (FS) and Sigsbee 2B - No Free Surface (NFS) use the same
structural model as Sigsbee2A but the velocity contrast at the water bottom has
been increased to a normal level thus generating significant internal and FS
multiples. These datasets are released in October 2002. The Sigsbee2B dataset is featured in paper SP3.8 "Observations from
the Sigsbee2B synthetic dataset" at the 2002 SEG meeting in
Salt Lake City.
is a simple 3D numeric model, which like the Sigsbee datasets, is modeled after
salt structures on the Sigsbee scarp in the
Gulf of Mexico.
The model is roughly 40 km E-W by 50 km N-S by 10 km deep. There is no
synthetic data to accompany this model.
