MOSAiC, the largest Arctic expedition in history
This talk will give an overview of the Multidisciplinary drifting Observatory for the Study of Arctic Climate -- MOSAiC, the largest Arctic expedition in history. The expedition started in September 2019, when German research ship RV Polarstern left Tromsø, Norway and headed towards the North Pole to be frozen in with the ice for a year.
On board among the various groups participating in the expedition, were the scientists and technicians from the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program, managing several shipping containers full of instruments for studying the properties of the Arctic atmosphere. The presenter of this talk spent a month and a half in the Arctic, setting up atmospheric aerosol measurements as part of the ARM deployment within MOSAiC.
The talk will give a background of the expedition, explain the role of the DOE ARM program in it, and share the personal experiences of the presenter working in the challenging Arctic conditions.
Janek Uin graduated from University of Tartu in 2011 and defended his PhD thesis on aerosol measurements. Since 2015 he works as a staff scientist at the Brookhaven National Laboratory in New York as part of the U.S. DOE ARM program. He is responsible for conducting atmospheric aerosol measurements at the ARM measurement sites situated across the world, with the 30+ field instruments under his care.
Physicumi seminarid on mõeldud füüsikute ja materjaliteadlaste, aga ka teiste loodus- ja täppisteadlaste laiale ringile (alates bakalaureuse astme üliõpilastest) ning püüavad avada seda, mis mingis valdkonnas on parasjagu oluline ja uudne või kuhu teatud uurimissuund on tänaseks välja jõudnud.
