Abstract:
This data set reports the chemistry of porewater in the SPRUCE plots located in the S1 bog (located in the Marcell Experimental Forest, Minnesota). These data are the pre- and post-treatment data from the SPRUCE experimental treatments (warming and elevated carbon dioxide [CO2]). There are 10 experimental plots in SPRUCE: 5 temperature treatments (+0, +2.25, +4.5, +6.75, +9°Celsius [C]) at ambient CO2, and the same 5 temperature treatments at elevated CO2. There are 7 additional ambient plots without experimental chambers.

Deep peat heating was initiated in the 10 experimental plots in June 2014. Aboveground warming was then added in August 2015 to achieve whole-ecosystem warming. Elevated CO2 was added to half the warming treatments in June 2016. Porewater samples were collected from one nest of 6 piezometers installed in a hollow in each of the 17 SPRUCE plots.

Water samples were analyzed for pH, specific conductivity, nutrient concentrations (ammonium, nitrate, soluble reactive phosphorus, total nitrogen, total phosphorus), cation concentrations (calcium, potassium, magnesium, sodium, aluminum, iron, manganese, silicon, strontium), anion concentrations (chloride, sulfate), and total organic carbon concentrations.
