Tim Kane (WHOI) on the float rig supporting the OBS on Skilak Lake, Alaska. This is part of a USGS effort, in collaboration with partners from the Woods Hole Oceanographic Institution Ocean Bottom Seismic Instrument Center, to create a record of past earthquakes from Skilak Lake on the Kenai Peninsula of Alaska.

Brian Andrews (USGS) pulling in Hannah Brewer (WHOI) during fieldwork on Skilak Lake, Alaska to create a record of past earthquakes from Skilak Lake on the Kenai Peninsula of Alaska. In May 2024, they deployed two seismographs on the bottom of the lake and eight seismographs on land around the lake. Each instrument will collect data there for about 1 year.
