OSU receives grant to study links between changing ocean conditions, movement of fish and geopolitical tensions

CORVALLIS, Ore. – An Oregon State University researcher has been awarded a three-year, $1.4 million grant from the U.S. Department of Defense to lead a study about the movement of fish stocks due to changing climate conditions and the potential geopolitical tensions that could result from that shift.

Ship launch marks key milestone in OSU-led construction of new U.S. oceanographic research vessels

HOUMA, La. – The first of three new oceanographic research vessels dedicated to advancing marine science along U.S. coasts was successfully launched Thursday.

The ship, R/V Taani, is being constructed as part of a project, led by Oregon State University and funded by the U.S. National Science Foundation, to provide scientists with valuable new tools to study critical issues such as rapidly changing ocean conditions and human impacts on the marine environment.

Massive iceberg discharges during the last ice age had no impact on nearby Greenland, raising new questions about climate dynamics

CORVALLIS, Ore. – During the last ice age, massive icebergs periodically broke off from an ice sheet covering a large swath of North America and discharged rapidly melting ice into the North Atlantic Ocean around Greenland, triggering abrupt climate change impacts across the globe.

These sudden episodes, called Heinrich Events, occurred between 16,000 and 60,000 years ago. They altered the circulation of the world’s oceans, spurring cooling in the North Atlantic and impacting monsoon rainfall around the world.

Oregon State names dean of College of Earth, Ocean, and Atmospheric Sciences

CORVALLIS, Ore. – Tuba Özkan-Haller, an Oregon State University professor, noted international oceanography researcher, and leader of university research initiatives and diversity, equity and inclusion actions, has been named dean of the university’s College of Earth, Ocean, and Atmospheric Sciences.

Özkan-Haller has served as acting or interim dean of the college since August 2021. Her appointment as dean is effective March 13.

Changing climate conditions likely facilitated early human migration to the Americas at key intervals, research suggests

CORVALLIS, Ore. – Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper published today in the Proceedings of the National Academy of Sciences shows.
