Data Acquired

Survey EquipmentSurvey InfoData Type(s)Data Collected
GeoEel digital streamer1416 linear kilometers of multichannel seismic reflection data were collected with an Applied Acoustics S-Boom source and a 32-channel Geometrics Geoeel streamer.Boomer

Sparker
Air Gun / Water Gun
Bubble Gun
RBRsolo-D depth logger5 RBR solo depth loggers were spaced along the length of the active seismic streamer sections to log streamer depths during acquisitionDepth
AML MVP30422 water column sound velocity profiles were collected with an AML MVP30 moving vessel profiler.Sound Velocity
S-Boom seismic sourceThe data associated with this system are attached to the GeoEel streamer. Multichannel seismic-reflection data were shot using and Applied Acoustics S-Boom three plate boomer powered by an Applied Acoustics CSP-D power supply that was set to output 600 Joules.Boomer
