Bering Land Bridge Cruise 

A team of scientists from the University of Alaska Fairbanks, USGS, and other partnering organizations were aboard the Research Vessel (R/V) Sikuliaq during the month of August 2023 to study conditions that existed on the Bering Land Bridge during the last ice age. USGS Research Geologist Jenna Hill was part of the research team that collected samples from beneath the sea floor to learn about the vegetation and climate of the region around 25,000 years ago.

From August 13 – September 10, 2023, members from the Global Marine Minerals Group were aboard the R/V Falkor (too) to the Western Galápagos Spreading Center to investigate active and inactive hydrothermal systems there, as part of an expedition with the Schmidt Ocean Institute. USGS scientists Amy Gartman, Kaitlin Adamcyzk, and Jaycee Favela were part of a team that collected critical marine mineral and sediment samples to be studied at PCMSC.

Hawai’ian Drowned Reefs 

An international scientific research expedition, carried out on behalf of the International Ocean Discovery Program (IODP), aims to recover a record of past climate and reef conditions off the coast of Hawai’i. USGS Research Oceanographer Nancy Prouty is part of a team of 29 scientists from Australia, Austria, China, Denmark, France, Germany, India, Japan, the Netherlands, Great Britain and the USA that will participate in the two-month research expedition aboard the multipurpose vessel MMA Valour, which left the port of Honolulu at the end of August.
