Sigsbee2 Models

Introduction

The Subsalt Multiples Attenuation and Reduction Technology Joint Venture (SMAART JV) publicly released several data sets between September 2001 and November 2002. These synthetic data model the geologic setting found on the Sigsbee escarpment in the deep water Gulf of Mexico. Additional information may be found at: www.delphi.tudelft.nl/SMAART/. The data sets remain the property of SMAART and are used under the agreement found at the SMAART site listed above.

The file sigsbee/FILES lists all files contained in the Sigsbee2 repository of Madagascar and is reproduced below in Table 1. Any of these files may be downloaded to local machines using ftp protocols.

The Sigsbee2 data are separated into two distinct categories, A and B. They share the same general model geometry and structure, however, the A model has a soft water to seafloor boundary while the B model features a more realistic hard boundary. As a result data produced in the B model features multiple events. The Sigsbee2B data set was featured in paper SP3.8 "Observations from the Sigsbee2B synthetic data set" at the 2002 SEG meeting in Salt Lake City.
