ArCS Arctic Challenge for Sustainability Project

The Arctic Cruise by the Oceanographic Research Vessel Mirai in 2019

The Arctic Cruise by the Oceanographic Research Vessel Mirai in 2019

The oceanographic research vessel Mirai, operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), will be on an Arctic cruise again in 2019 as part of the ArCS activities.

In this year, in tandem with the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC), an international joint Arctic observation project mainly led by the Alfred Wegener Institute (AWI, Germany), we will conduct an observation project in October, When the freezing season is getting delayed, with an aim to clarify how the atmospheric and oceanographic environments and marine ecosystem in the Arctic Ocean and the surrounding seas are changed with sea-ice decline.

  • Cruise period: 45 days from Friday, September 27, to Sunday, November 10, 2019
  • Regions to be surveyed: Arctic Ocean, Bering Sea, North Pacific Ocean

Map of the waters to be surveyed (planned)

The red dotted lines represent the vessel’s direction of travel. The black dots, blue dots, and yellow triangles indicate the planned observation points. The observation schedule is subject to change depending on weather, sea ice, and other conditions.

What is the MOSAiC Project?

In the MOSAiC project, a German icebreaker is to remain in the sea ice in the central area of the Arctic Ocean for one year from October 2019 for year-round observation. This project is intended to collect a large volume of comprehensive data on the atmosphere, sea ice, oceans, ecosystems, etc. that have been insufficiently monitored, and leverage the data for validation and development of numerical models.
