Water depth was measured using an Echo sounder (HONDEX PS-7 LCD) and a calibrated rope for verification. 100 cm-long parallel cores were collected at 2 m water depth using a Russian peat corer and supported by an UWITEC gravity coring system. Cores were stored in waterproof sealed, transparent PVC plastic tubes in cool and dark conditions. After the field season, the cores were transported to Potsdam, Germany and stored at 4°C in the cold rooms at AWI. The cores did not experience any visible drying or surface oxidation during PG2201-W Water sample WS 2013-03-24T00:00:00 61.95848 129.40833 0 PG2201-IC Ice drill ICEDRILL 2013-03-24T00:00:00 61.95848 129.40833 0 PG2201-3 Push corer PUC 2013-03-24T00:00:00 61.95848 129.40833 0 PG2201-2 Russian corer RUSC 2013-03-24T00:00:00 61.95848 129.40833 0 PG2202-W Water sample WS 2013-03-25T00:00:00 62.13088 129.48670 2.5 Ice thickness: 92 cm PG2202-IC Ice drill ICEDRILL 2013-03-25T00:00:00 62.13088 129.48670 2.5 Ice thickness: 92 cm PG2202-1 Push corer PUC 2013-03-25T00:00:00 62.13088 129.48670 2.5 Ice thickness: 92 cm PG2202-2 Russian corer RUSC 2013-03-25T00:00:00 62.13088 129.48670 2.5 Ice thickness: 92 cm PG2204-W Water sample WS 2013-04-01T00:00:00 56.05077 130.87947 901 Ice thickness: 83 cm PG2205-1 Gravity corer GC 2013-04-01T00:00:00 56.05622 130.86790 901 Ice thickness: 80 cm PG2205-2 Gravity corer GC 2013-04-01T00:00:00 56.05622 130.86790 901 Ice thickness: 80 cm PG2205-3 Gravity corer GC 2013-04-01T00:00:00 56.05622 130.86790 901 Ice thickness: 80 cm PG2206-1 Gravity corer GC 2013-04-01T00:00:00 56.06340 130.85830 901 Snow thickness: 34 cm; Ice thickness: 85 cm PG2206-2 Gravity corer GC 2013-04-01T00:00:00 56.06340 130.85830 901 Ice thickness: 85 cm PG2206-Snow Snow/ice sample SNOW 2013-04-01T00:00:00 56.06340 130.85830 901 Ice thickness: 85 cm PG2203-1 Gravity corer GC 2013-04-01T00:00:00 56.05077 130.87947 901 Ice thickness: 83 cm PG2207-2 Gravity corer GC 2013-04-01T00:00:00 56.06788 130.85558 901 Ice thickness: 84 cm PG2207-W Water sample WS 2013-04-01T00:00:00 56.06788 130.85558 901 Ice thickness: 84 cm PG2207-1 Gravity corer GC 2013-04-01T00:00:00 56.06788 130.85558 901 Snow thickness: 33 cm; Ice thickness: 84 cm PG2203-2 Gravity corer GC 2013-04-01T00:00:00 56.05077 130.87947 901 Ice thickness: 83 cm PG2204-1 Gravity corer GC 2013-04-01T00:00:00 56.05077 130.87947 901 Ice thickness: 83 cm PG2204-2 Piston corer PC 2013-04-01T00:00:00 56.05077 130.87947 901 Ice thickness: 83 cm PG2208 Composite Core COMPCORE 2013-04-02T00:00:00 56.05615 130.86780 901 Ice thickness: 80 cm PG2208-W Water sample WS 2013-04-02T00:00:00 56.05615 130.86780 901 Ice thickness: 80 cm PG2208-3 Piston corer PC 2013-04-02T00:00:00 56.05615 130.86780 901 Ice thickness: 80 cm PG2208-2 Piston corer PC 2013-04-02T00:00:00 56.05615 130.86780 901 Ice thickness: 80 cm PG2208-1 Gravity corer GC 2013-04-02T00:00:00 56.05615 130.86780 901 Ice thickness: 80 cm PG2112-1 Gravity corer GC 2013-04-03T00:00:00 56.08195 130.89398 901 Ice thickness: 92 cm PG2144-1 K1 Gravity corer GC 2013-04-03T00:00:00 56.05520 130.90350 901 Ice thickness: 85 cm PG2145-1 L1 Gravity corer GC 2013-04-03T00:00:00 56.04760 130.92770 901 Ice thickness: 86 cm PG2146-1 M1 Gravity corer GC 2013-04-03T00:00:00 56.04680 130.93000 901 Ice thickness: 86 cm PG2147-1 N1 Gravity corer GC 2013-04-03T00:00:00 56.04570 130.93430 901 Ice thickness: 85 cm PG2148-1 O1 Gravity corer GC 2013-04-03T00:00:00 56.04530 130.93660 901 Ice thickness: 85 cm PG2209-1 Gravity corer GC 2013-04-03T00:00:00 56.07342 130.84988 901 Ice thickness: 94 cm PG2210-1 Gravity corer GC 2013-04-03T00:00:00 56.07813 130.84650 901 Ice thickness: 91 cm PG2211-1 Gravity corer GC 2013-04-03T00:00:00 56.08457 130.86938 901 Ice thickness: 94 cm PG2143-1 J Snow/ice sample SNOW 2013-04-03T00:00:00 56.09510 130.95030 901 PG2113-1 Gravity corer GC 2013-04-03T00:00:00 56.05405 130.83298 901 Ice thickness: 87 cm PG2114-1 Gravity corer GC 2013-04-03T00:00:00 56.04133 130.83587 901 Ice thickness: 85 cm PG2115-1 Gravity corer GC 2013-04-03T00:00:00 56.02012 130.83742 901 Ice thickness: 106 cm PG2116-1 Gravity corer GC 2013-04-03T00:00:00 56.02175 130.80367 901 Ice thickness: 85 cm PG2116-X13 Observation OBSE 2013-04-03T00:00:00 56.01268 130.82257 901 Ice thickness: 55 cm; thin ice due to methane?
