Survey Equipment | Survey Info | Data Type(s) | Data Collected |
---|---|---|---|
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 | |
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 | |
AML MVP30 | 422 water column sound velocity profiles were collected with an AML MVP30 moving vessel profiler. | Sound Velocity | |
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 | |
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 | |
OSIL Mega Multiple Corer | --- | Chemistry Geology Biology | |
Sparker | The sparker source was not used during 2022-004-FA | Sparker | No data was collected |
Reson T20-P | --- | Multibeam Water column reflectivity |
