Invited by ITP Prof. KONG Weidong of Laboratory of Alpine Ecology and Biodiversity (LAEB), Prof. Hisayuki YOSHIKAWA from Hokkaido University, Japan, will conduct academic exchanges at ITPCAS in early June. He will also give a presentation during his visit, introducing his research on the global carbon cycle.

Your attendance is warmly welcome!

Title: Biogeochemical studies of global carbon cycle

Presenter:Prof.Hisayuki Yoshikawa

Chair: Prof. KONG Weidong

Venue: Room 915, ITPCAS building

Time: 3.30–4.:30 pm, June 4, 2013

Introduction

Professor Hisayuki Yoshikawa received his PhD from Kyoto University in 1980. From 1980 to 2002, he worked successively as research scientist, senior research scientist and head of the Geochemical Laboratory, Meteorological ResearchInstitute of Japan. He was appointed as professor of Graduate School of Environmental Science, Hokkaido University since 2002. His researches cover air-sea carbon exchange in the open ocean (especially in the Southern Ocean),variations in oceanic carbonate system in the open ocean, air-land carbon exchange, biogeochemical cycles of greenhouse gases other than CO2, determination of fractionation factor of gases between air and seawater, and role of sea-ice on the biogeochemical cycle etc. He is now maintaining Rishiri Observatory (RIO), the northernmost atmospheric observation station in Japan. Specifically, he uses Radon-222 as a tracer to estimate the sources and sinks of atmospheric greenhouse gases in the East Asia. He is also a leading scientist of the GRENE project (2011–2016) of Japan. For more information, please refer to http://geos.ees.hokudai.ac.jp/hyoshika/index.html.
