| Equipment | Usage description | Data types | Datasets |
|---|---|---|---|
| Ocean Bottom Seismometer | Nine Sercel micrOBS instruments were deployed in an array around the calculated epicenter of a Dec 5th, 2024, M7.0 earthquake offshore Mendocino, CA to record aftershocks following the main event. Eight of the nine instruments deployed were successfully recovered. | Ocean Bottom Seismometer | (no data reported) |
| Sparker | The AA Delta sparker was discharged in a circle around the recovery location so that OBS recordings of the shots could be used to improve bottom location control by acoustic ranging calculations during post-processing. Precise shot times were recorded in the hypack navigation. | Sparker | (no data reported) |
| DGPS | DGPS providing ship positions during recovery. | Navigation | (no data reported) |
