A University of 蜜桃影像 Fairbanks-led expedition embarks this week for a 40-day scientific cruise to assess the state of the eastern Arctic Ocean. The expedition, which is part of the , includes 27 participants from the United States, Russia, Japan and Denmark.
鈥淓xtensive plans include monitoring of the state of the Arctic Ocean, ice and atmosphere in the area with the most pronounced climate changes,鈥 said chief scientist Igor Polyakov from the 蜜桃影像 International Arctic Research Center. 鈥淲e will make a lot of complex observations in this remote area of the planet.鈥
This marks the 13th NABOS expedition to the Arctic Ocean since 2002. Their goal is to compile a cohesive picture of climatic changes in the Eurasian and Makarov basins through continued monitoring. These basins are experiencing dramatic changes due to accelerated atmospheric warming and an influx .
Scientists aboard the research vessel Akademik Tryoshnikov will recover scientific sensors deployed during a 2018 cruise and set out new equipment to continuously record temperature, salinity and currents at different ocean depths. The team will also conduct extensive ship-based surveys, gathering water and ice samples for future chemical analysis.
The data collected will strengthen scientific understanding of Arctic currents, ocean circulation and interactions between the Arctic and Atlantic oceans.
NABOS鈥 repeated oceanographic surveys and the long-term maintenance of ocean sensors has been made possible through effective international collaboration between scientists from a wide range of institutions and scientific disciplines.
This research is funded by the U.S. National Science Foundation.
