The study demonstrates that severe OA in a large part of the Arctic results from a completely different source\/mechanism than what has previously been considered. A decade-worth of observations shows that OA on the Siberian Shelf Seas is not caused by CO\u2082 uptake from the atmosphere but by a novel horizontal coupling of several different climate change effects: OA is caused by the input of freshwater discharge and degradation of translocated terrestrial organic carbon released from thawing permafrost. The data set includes (i) Carbonate system data, other hydrochemical data, and estimates of aragonite saturation levels 1999\u20132011; (ii) salinity data; (iii) \u03b4\u00b9\u00b3C of DIC from an expedition in 2007; (iv) \u03b4\u00b9\u2078O-H\u20820 from the ISSS-08 expedition and results of calculations for fractional freshwater contributions from sea ice melt vs rivers; \u03b4\u00b9\u00b3C of OC in surface sediments.","url":"http:\/\/bolin.su.se\/data\/semiletov-2016-carbon-1","keywords":["Marine","Arctic carbon","Arctic","Climate","Marine","Carbon cycling","Ocean acidification","East Siberia permafrost","Earth Science > Oceans > Ocean Chemistry > Carbon"],"creator":{"@type":"Person","name":"Igor Semiletov, Natalia Shakhova, \u00d6rjan Gustafsson"},"citation":"Semiletov, Igor, Irina Pipko, \u00d6rjan Gustafsson, Leif G.
