We used three soil layers ((i) surface active layer, (ii) bottom active layer, (iii) permafrost), three different temperatures ((i) 1°C, (ii) 4°C, (iii) 8°C), and two treatments ((i) control without substrate addition, (ii) amended with 13C labeled Carex aquatilis. For each sample we used 4 aliquots. CO2 production was measured via gas chromatography. The isotopic signature of the produced CO2 was measured via isotope-ratio mass spectrometry. To differentiate between soil organic matter- (SOM-) and Carex-derived CO2 in amended samples, we used an isotopic mixing model. In control incubations all CO2 is SOM-derived." ; dct:identifier "https://doi.pangaea.de/10.1594/PANGAEA.864865" ; dct:issued "2026-05-20T14:16:27.946549"^^xsd:dateTime ; dct:modified "2026-05-21T21:30:06.345113"^^xsd:dateTime ; dct:publisher [ a foaf:Agent ; foaf:homepage ; foaf:name "PANGAEA" ], [ a foaf:Agent ; foaf:homepage ; foaf:name "PANGAEA" ] ; dct:spatial [ a dct:Location ; locn:geometry "POINT (126.4898 72.3744)"^^gsp:wktLiteral ] ; dct:title "Aerobic carbon dioxide production data of permafrost-affected soils of the northeast Siberian polygonal tundra under different treatments" ; schema:about [ a schema:Thing ; schema:name "oceans" ; schema:url "https://dataportal.dev.inkode.org/group/12b8aa5c-0c95-425f-b52e-b242ef19da2c" ], [ a schema:Thing ; schema:name "human-dimensions" ; schema:url "https://dataportal.dev.inkode.org/group/a638b0e5-f721-4879-b23d-58052447b707" ], [ a schema:Thing ; schema:name "sun-earth-interactions" ; schema:url "https://dataportal.dev.inkode.org/group/d442910f-0139-4e53-9505-29017a7c4ecb" ] ; schema:citation "https://doi.org/10.1594/PANGAEA.864865" ; schema:contributor "pangaea" ; schema:creator [ a schema:Organization ; schema:contactPoint [ a schema:ContactPoint ; schema:contactType "customer service" ; schema:name "Alfred Wegener Institute for Polar and Marine Research (AWI - Partner 7)" ; schema:url "https://doi.pangaea.de/10.1594/PANGAEA.864865" ] ; schema:name "Alfred Wegener Institute for Polar and Marine Research (AWI - Partner 7)" ] ; schema:dateModified "2026-05-21T21:30:06.345113" ; schema:datePublished "2016-09-22", "2016-09-22T00:00:00" ; schema:description "We aerobically incubated soil samples from a polygon center (P3, 72° 22.5 N, 126° 29.4 E) on Samoylov, Northeast Siberia for 150 days.
