The Pacific Coast Seismic Assessment for Faults and Earthquakes (PACSAFE) multi-year ocean bottom seismometer (OBS) program conducted its first deployment in October 2023 off the west coast of British Columbia. This multi-institution collaboration, led by the University of British Columbia partnered with the Geological Survey of Canada and the University of Victoria, deployed 26 new broad-band OBS from the National Facility for Seismological Investigations (NFSI) run by Dalhousie University. The PACSAFE program is targeting an enhanced understanding and characterization of seismicity and faulting from offshore northern Vancouver Island to northern Haida Gwaii. These new OBS will facilitate more precise earthquake locations and structural imaging, ultimately contributing to enhanced assessment of seismic hazard along the southwest and central BC coast. In mid-November 2023, two OBS self-released from the seafloor off Queen Charlotte Sound and drifted into Hecate Strait. Though both instruments were tracked by GPS, only one was recovered. Here we present a summary of the 2023 Leg-1 Deployment cruise, outline the Leg 2 recovery and redeployment cruise in July 2024, discuss potential causes for the early release of two instruments, and illustrate the challenges and successes of attempting recovery during the stormy winter months on the BC Coast. Finally, we present preliminary analysis and results from the recovered instrument, L129, including a preliminary analysis of its noise levels, component orientations, and earthquake catalogue for the recording time period of this station, which consists of >150 located events (compared to ~45 in the National Earthquake Database over the same time period).
