Datasets produced in this activity

Dataset name Equipment Description Dataset contact
Multichannel sparker seismic-reflection data between Icy Point and Dixon Entrance, Gulf of Alaska from 2016-08-07 to 2016-08-26 Multichannel This data release contains high-resolution multichannel seismic (MCS) reflection data collected in August of 2016 along the southeast Alaska continental margin. Structure perpendicular MCS profiles were collected along the Queen Charlotte-Fairweather fault. The data were collected aboard the R/V Norseman using a Delta sparker sound source and recorded on a 64-channel digital streamer. Subbottom acoustic penetration spans up to several hundreds of meters, and is variable by location. Alicia F Balster-gee
