Equipment used

Equipment Usage description Data types Datasets
GeoEel digital streamer 1416 linear kilometers of multichannel seismic reflection data were collected with an Applied Acoustics S-Boom source and a 32-channel Geometrics Geoeel streamer. Boomer, Multichannel, Sparker, Air Gun / Water Gun, Bubble Gun (no data reported)
RBRsolo-D depth logger 5 RBR solo depth loggers were spaced along the length of the active seismic streamer sections to log streamer depths during acquisition Depth (no data reported)
AML MVP30 422 water column sound velocity profiles were collected with an AML MVP30 moving vessel profiler. Sound Velocity (no data reported)
S-Boom seismic source The 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 (no data reported)
Edgetech chirp subbottom profiler 512i 1,992 linear kilometers of chirp sub-bottom data were collected with an Edgetech 512i chirp sub-bottom profiler. Sub Bottom Profiler (no data reported)
OSIL Mega Multiple Corer Chemistry, Geology, Biology (no data reported)
Sparker The sparker source was not used during 2022-004-FA Sparker (no data expected)
Reson T20-P Multibeam, Water column reflectivity (no data reported)
