Jonathan Warnock has been selected to represent the United States on an upcoming
research expedition with the International Ocean Discovery Project.
Scientists from around the world will spend 60 days at sea collecting
marine sediment cores in order to analyze Earth’s past ecology and
climate. Expedition 382, “Iceberg Alley and Subantarctic Ice and Ocean
Dynamics,” will investigate the history of the Antarctic Peninsula going
back to the early Miocene, almost 30 million years.
Antarctic Peninsula is the northernmost, and hence most vulnerable,
portion of the continent. In recent years it has seen the most rapid
deglaciation of any part of Antarctica.
The key goals of the
research expedition are to understand the development of ice on the
peninsula, past periods of deglaciation, and the interactions of ice
sheets and the Southern Ocean.
Warnock will sail as a
micropaleontologist, with the primary goals of giving ages to the
sediments and identifying changes to marine ecology driven by changes to
ice volume and ocean circulation.
