| contents | Sea floor depth under Ekström Ice Shelf, Antarctica - from seismic reflection profiles collected between 2010 and 2018. For each seismic profile, the reflection time of the sea floor and ice-shelf base was identified and the depth to the sea floor was calculated using an ice velocity of 3601 m/s a sea-water velocity of 1451 m/s. The depths are referenced to mean sea-level (geoid EIGEN-6C4 ). The seismic data used here were collected using two different seismic vibroseis sources. The same snow streamer was used for all data acquisition - a 1500 m long, 60 channel snow streamer, with 25 m group spacing. Each group contains eight gimballed P-wave SM-4, 14 Hz geo-phones. Please note these data are the point data used to create the gridded bathymetry product of the region, found here: doi:10.1594/PANGAEA.907951 Details of data acquisition and processing are given here: doi:10.1029/2019GL086187. |
