Bransfield Strait ocean bottom seismometer (OBS) data
Listed in NASA Earthdata CMR
This was an OBS program in the Bransfield Strait, Antarctica carried out on two cruises of the Nathaniel B. Palmer.
Description
The main objective was to examine crustal thinning associated with the active extension in the Bransfield Strait following up on a 1991 MCS seismic program (EW9101). The data set consists of dip profiles 1/7, 3, and 5 (7 was a reshoot of 1) and strike profiles 2, 4, 6, 9, and 10.
Each profile is 150-200 km long, and was recorded by 10-11 ocean bottom seismometers (OBSs) at a spacing of 15-20 km. The data is in SEG-Y format, with all navigational information in the headers.
