Data were recorded on Ocean Bottom Seismic Receivers 1 and 19, and shots were selected to maintain offsets of approximately 200m, with a wide but uneven azimuth distribution. This was done to study azimuthal attenuation anisotropy for near-vertically travelling P-waves. The data are in SEGY format, with file names in the form: Rec*_**_***_nmo.sgy where * is receiver number ** is GI for the GI gun source and Dura for the surface sparker source *** is X for X component, Y for Y component, Z for Z component and H for hydrophone.
