Report on lake/marine sediment coring from ice surface (JARE-58/59)

Lake and marine sediment coring were carried out in the Soya Coast in East Antarctica, during the 2017⊖2018 summer season as part of the 58/59th Japanese Antarctic Research Expedition (JARE). The field party consisted of one biologist from the JARE 58 wintering team, two geomorphologists and two biologists from an advance team of the JARE 59 summer members. Airborne access to Antarctica for the advance team was provided by Dronning Maud Land Air Network (DROMLAN). However, a continental flight for the outward way was carried out by the Norwegian Polar Institute (NPI) due to a trouble of scheduling of DROMLAN flights. Consequently, the JARE 59 members arrived at Syowa station via Troll station and Novolazarevskaya Airbase in early November 2017. Because the field team was isolated in the Kizahashi hut from late November until the arrival of Shirase due to sea ice conditions, one medical doctor also joined the field party. In total 26 sediment cores were obtained from 23 lakes and shallow marine sites in West Ongul, Langhovde, Skarvsnes, and Skallen area using the newly developed portable piston corer. This report summarizes activities of this field expedition including fieldwork, logistics, and weather observation.
