A workshop titled “Canada-Japan Future Collaboration Workshop on Arctic Environment based at Canadian High Arctic Research Station (CHARS) Campus” was held on Monday, 1 July 2019 and Tuesday, 2 July 2019, at CHARS, Cambridge Bay, Canada. The goal of the workshop was to deliver and exchange information of on-going and future possible research projects in the Arctic environment surrounding  Cambridge Bay、Nunavut with Canadian counterparts and local stakeholders. The meeting was organized in collaboration with Canadian counterparts at Polar Knowledge Canada (POLAR) to strengthen the bilateral research collaboration between Canada and Japan.

Accurate weather forecasts form an imperative component of field observational campaigns. Accuracy is important, of course, but understanding the uncertainty is just as crucial. Observations on the hand are vital for Numerical Weather Prediction (NWP) models and centers for numerous reasons: improving forecasts through data assimilation, assessing their performance, and advancing model physics through process evaluations. Maximizing the values of observations and NWPs intuitively require communication between both parties. Aiming to initiate discussions in this context, a leading NWP center, European Centre for Medium-range Weather Forecasts (ECMWF) hosted a workshop during the 10th and 13th of June, 2019, titled “Observational campaigns for better weather forecasts” in Reading, UK. The workshop oral sessions included: model diagnostics using data, cloud physics, tropical cyclones, stratosphere, mountains, and winds, and polar processes. 4 members from the ArCS project participated with the Theme 1 PI presenting an oral talk from a perspective of a NWP user during the 2018 R/V Mirai field campaign while the others had poser presentations regarding sea ice forecast and air temperature biases and uncertainty of satellite-retrieved sea ice concentration. More broadly, discussions during the workshop included how to strengthen the link between observational campaigns and NWP centers, uncertainty estimation of the observation and models, and how to improve numerical models with past observational campaigns.

I stayed at Woods Hole Oceanographic Institution (WHOI) from 13th February to 14th April with support from the ArCS’ program for young researchers’ overseas visits.

During my stay, I got sediment samples taken by Healy, an icebreaker ship of United States, and investigated diatom resting stage cells in sediments of the northern Bering Sea, Chukchi and Beaufort Seas. Diatom resting stage cells are like “seeds” which have high durability. They are formed under nutrient- and light-limited conditions.

Second round-table conference on Arctic between government officials and researchers was held on Monday, 10th June 2019.

There were about 30 participants consisting of about 20 researchers, mainly from ArCS participants, and 10 government officials from the Cabinet Office, the Ministry of Foreign Affairs, MEXT and other ministries.

In order to face and respond to the global warming and related change in the Arctic, action should be taken not only by way of natural science, engineering science, and social science individually, but also by integrating approach. On the basis of this, the symposium had been carried out by researchers from two research fields as natural/engineering science (Theme-1; working on “Predictability study on weather and sea-ice forecasts linked with user engagement”) and social science (Theme-7 working on “People and Community in the Arctic: Possibility of Sustainable Development”) from the ArCS Project together.
