A team of USGS scientists, in collaboration with partners from the Woods Hole Oceanographic Institution Ocean Bottom Seismic Instrument Center, are aiming 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.

A cross-section of an Arctic speleothem showing growth layers of calcite deposited over hundreds of thousands of years. This speleothem only grew during intervals of past permafrost thaw (i.e., interglacials), when drip water could percolate into the cave through the unfrozen epikarst.

Map of area where the USGS and USFWS may observe Pacific walrus during marine expeditions on the RV Norseman II starting in summer of 2024. Crosshatching in the map shows the general area where the Norseman II may sail to observe walruses in the summer of 2024, as part of a USGS and USFWS project to study Pacific walrus population dynamics.

The term “legacy data” refers to project data that are complete, or may be resurrected in the future, that were previously stored in old or obsolete formats and thus, difficult to access. These data are an important record of past ecosystem status and part of the USGS commitment to deliver actionable information relevant to decision makers.

This image shows the estimated outline and area (in square meters) occupied by Pacific walrus at a large coastal haulout in Chukotka Russia in 2023 at Cape Serdtse Kamen. The image is derived from images in 2022 and 2023 from a variety of Earth observing satellite imagery sources collected at known walrus coastal haulouts in Alaska and Chukotka, Russia.
