SPRUCE S1 Bog Pretreatment Photosynthesis and Respiration for Black Spruce: 2010-2013
This data set contains biochemical, morphological, and physiological data collected between 2010 and 2013 on mature black spruce (Picea mariana) trees at the S1 bog site in northern Minnesota, located 40 km north of Grand Rapids in the USDA Forest Service Marcell Experimental Forest (MEF). These data were collected prior to the initiating of heating and elevation of CO2 for the SPRUCE experiment to assess the response of northern peatland ecosystems to increases in temperature and exposures to elevated atmospheric CO2 concentrations. Note that file SPRUCE_4_cohort_Rd_data_20151119.csv was replaced on November 19, 2015.
