Overview of the SLOPE2024 for sea ice biogeochemistry and physics in Saroma-ko Lagoon, Hokkaido, Japan
The Sea Ice Physico-Chemistry and Ecosystems 2024 (SLOPE2024) workshop was conducted in the Saroma-ko Lagoon, Hokkaido, Japan from the middle of February to the beginning of March 2024. The aim of SLOPE2024 was to study the physical, chemical, and biological characteristics and processes of the sea ice environment, develop/intercompare methods, test equipment, and train/educate personnel for studies of polar regions. We compared the biogeochemical and physical ice characteristic between ice originating from seawater and river water. The ferrous iron (Fe(II)) content of under-ice water was measured by luminol-chemiluminescence detection using the standard addition method. For an intercomparison experiment, the difference in sea ice chlorophyll a concentration between freeze-drying and thawing methods was tested. In addition, sinking rate, flux, and size distribution of particles beneath sea ice were examined. Furthermore, we carried out experiments on sea-salt aerosol emission from sea ice and for the effect of sea ice cracks on the biogeochemical components in an artificial crack pool. Finally, the workshop explored how each of us gathered here imagine the Arctic in this place where we feel like being a part of the Arctic-ness, just as we are part of our society and the Earth.
