| Summary: | The sampling campaign was conducted during the austral summer between December 2016 and February 2017 as a part of the 58th Japanese Antarctic Research Expedition. On Sôya Coast (Lützow-Holm Bay, East Dronning Maud Land, East Antarctica), there are hundreds of lakes with variable water chemistry which were formed during the last 7,000 years under the glacier retreat and iso-static uplifts that occurred after the Last Glacial Maximum. Water samples were collected either at the center of the lakes or at the shore into 550-mL PET bottles after rinsing more than three times with the collected water. Within a few hours after sampling, samples were filtered through pre-combusted (450dc, >3 h) glass-fiber filters (nominal pore size 0.3mm, GF-75, Advantec, Tokyo, Japan) into pre-combusted glass bottles (see doi:10.1016/J.WATRES.2019.114901). The filtered samples were immediately spiked with sodium azide (final concentration of 0.02%) for preservation, stored dark at 5dc, and shipped back to Japan. DOM was ... |
