Data were obtained from water samples collected between 2007 and 2009 from the Glacial Lake Agassiz Peatlands (GLAP) in northern Minnesota. Data is divided up by type of sample and year of sample collection. Stable isotope and concentration data was obtained at Florida State University. Radiocarbon data was obtained from National Ocean Sciences Accelerator Mass Spectrometry Facility (NOSAMS). 1. ts01.doc (Figures 1, 2, and 4) Radiocarbon data of pore water samples from 2007. 1.1 Column Site, sampling site name 1.2 Column Depth (cm), depth within peat column, units in cm, measured from water table 1.3 Column Type, type of sample collected: dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), or other (methane). 1.4 Column δ13C (‰), stable, heavy isotope of carbon, units in ‰ 1.5 Column Accession #, NOSAMS identification number of the sample 1.6 Column F modern, the fraction of modern carbon within a sample 1.7 Column Age (years BP), age defined as years before present (BP, defined as 1950), unit in years BP, calculated from the δ13C-corrected Fraction Modern 1.8 Column Δ14C (‰), radiocarbon values of the sample, units of ‰, corrected for decay and δ13C 2. ts02.doc (Figures 1, 2, and 4) Radiocarbon data of pore water samples from 2008. 2.1 Column Site, sampling site name 2.2 Column Depth (cm), depth within peat column, units in cm, measured from water table 2.3 Column Type, type of sample collected: dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), or other (methane). 2.4 Column δ13C (‰), stable, heavy isotope of carbon, units in ‰ 2.5 Column Accession #, NOSAMS identification number of the sample 2.6 Column F modern, the fraction of modern carbon within a sample 2.7 Column Age (years BP), age defined as years before present (BP, defined as 1950), unit in years BP, calculated from the δ13C-corrected Fraction Modern 2.8 Column Δ14C (‰), radiocarbon values of the sample, units of ‰, corrected for decay and δ13C 3. ts03.doc (Figures 1, 2, and 4) Radiocarbon data of pore water samples from 2009. 3.1 Column Site, sampling site name 3.2 Column Depth (cm), depth within peat column, units in cm, measured from water table 3.3 Column Type, type of sample collected: dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), or other (methane). 3.4 Column δ13C (‰), stable, heavy isotope of carbon, units in ‰ 3.5 Column Accession #, NOSAMS identification number of the sample 3.6 Column F modern, the fraction of modern carbon within a sample 3.7 Column Age (years BP), age defined as years before present (BP, defined as 1950), unit in years BP, calculated from the δ13C-corrected Fraction Modern 3.8 Column Δ14C (‰), radiocarbon values of the sample, units of ‰, corrected for decay and δ13C 4. ts04.doc Radiocarbon data of CH4 gas bubbles collected in 2007 from within the peat column. 4.1 Column Site, sampling site name 4.2 Column Depth (cm), depth within peat column, units in cm, measured from water table 4.3 Column Type, type of sample collected: dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), or other (methane) 4.4 Column δ13C (‰), stable, heavy isotope of carbon, units in ‰ 4.5 Column Accession #, NOSAMS identification number of the sample 4.6 Column F modern, the fraction of modern carbon within a sample 4.7 Column Age (years BP), age defined as years before present (BP, defined as 1950), unit in years BP, calculated from the δ13C-corrected Fraction Modern 4.8 Column Δ14C (‰), radiocarbon values of the sample, units of ‰, corrected for decay and δ13C 5. ts05.doc DIC and dissolved CH4 concentration and stable isotope values for 2007 samples. 5.1 Column Site, sampling site name 5.2 Column Depth (cm), depth within peat column, units in cm, measured from water table 5.3 Column DIC (mM), concentration of dissolved inorganic carbon (DIC), units in mM 5.4 Column δ13C-DIC (‰), stable, heavy isotope of DIC, units in ‰ 5.5 Column CH4 (mM), concentration of dissolved methane, units in mM 5.6 Column δ13C-CH4 (‰), stable, heavy isotope of CH4, units in ‰ 6. ts06.doc DIC and dissolved CH4 concentration and stable isotope values for 2008 samples. 6.1 Column Site, sampling site name 6.2 Column Depth (cm), depth within peat column, units in cm, measured from water table 6.3 Column DIC (mM), concentration of dissolved inorganic carbon (DIC), units in mM 6.4 Column δ13C-DIC (‰), stable, heavy isotope of DIC, units in ‰ 6.5 Column CH4 (mM), concentration of dissolved methane, units in mM 6.6 Column δ13C-CH4 (‰), stable, heavy isotope of CH4, units in ‰ 7. ts07.doc DIC and dissolved CH4 concentration and stable isotope values for 2009 samples. 7.1 Column Site, sampling site name 7.2 Column Depth (cm), depth within peat column, units in cm, measured from water table 7.3 Column DIC (mM), concentration of dissolved inorganic carbon (DIC), units in mM 7.4 Column δ13C-DIC (‰), stable, heavy isotope of DIC, units in ‰ 7.5 Column CH4 (mM), concentration of dissolved methane, units in mM 7.6 Column δ13C-CH4 (‰), stable, heavy isotope of CH4, units in ‰ 8. ts08.doc Concentration data for pore water samples measured in 2007.
