Recovered 8 land seismic stations (SK03-10) and 1 OBS (SK01). The second OBS (SK02) did not surface; we suspect it is stuck in mud. SK10 shutdown due to low battery in March 2025. SK07 shutdown due to low battery in December 2024. All other stations were running upon recovery. Data were successfully downloaded from all recovered instruments. Used Alaska Science Center's R/V Lutris and R/V Moose Dancer (both 25' Boston Whalers) and a purpose-built float frame for OBS recovery. Personnel: Nathaniel Miller, Rob Witter, Eric Moore, Drake Singleton, Daniel Brothers, Tim Kane (WHOI), and Hannah Brewer (WHOI).
