Marcell Experimental Forest peat core extraction chemical analysis data (DOC, Fe, Ca, Mg, K, P, Al)
This data set reports iron (Fe), dissolved organic carbon (DOC), calcium (Ca), magnesium (Mg), potassium (K), phosphorus (P), and aluminum (Al) measured in extractions of soil cores sampled from two boreal peatlands, the S1 and S2 bogs, in the Marcell Experimental Forest (MEF) in Itasca County, Minnesota. The soil cores were sampled on September 2, 2017. Elements were quantified in extractions with hydrochloric acid, sodium dithionite, sodium sulfate, and sodium dithionite plus hydrochloric acid to examine how iron influences carbon and nutrient cycling in peatlands. The S1 and S2 sites are research catchments instrumented for hydrologic monitoring. The S1 bog is also the location of the Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment. These data are used, analyzed, and reported in Curtinrich et al. (2021, Ecosystems).

Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating Research (CiPEHR): leaf SLA, C, N, P, Ca, delta-13C, delta-15N at peak biomass, 2017
The Carbon in Permafrost Experimental Heating Research (CiPEHR) project addresses the following questions: 1) Does ecosystem warming cause a net release of C from the ecosystem to the atmosphere?, 2) Does the decomposition of old C, that comprises the bulk of the soil C pool, influence ecosystem C loss?, and 3) How do winter and summer warming alone, and in combination, affect ecosystem C exchange? We are answering these questions using a combination of field and laboratory experiments to measure ecosystem carbon balance and radiocarbon isotope ratios at a warming experiment located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. This data set includes carbon (C) and nitrogen (N) elemental and isotope content in leaves collected from winter warming, summer warming, and control treatment plots at CiPEHR.
Eight Mile Lake Research Watershed, Thaw Gradient: leaf SLA, C, N, P, Ca, Mg, delta-13C, delta-15N at peak biomass, 2017
In this larger study, we are asking the question: Is old carbon that comprises the bulk of the soil organic matter pool released in response to thawing of permafrost? We are answering this question by using a combination of field and laboratory experiments to measure radiocarbon isotope ratios in soil organic matter, soil respiration, and dissolved organic carbon, in tundra ecosystems. The objective of these proposed measurements is to develop a mechanistic understanding of the SOM sources contributing to C losses following permafrost thawing. We are making these measurements at an established tundra field site near Healy, Alaska in the foothills of the Alaska Range. Field measurements center on a natural experiment where permafrost has been observed to warm and thaw over the past several decades. This area represents a gradient of sites each with a different degree of change due to permafrost thawing. As such, this area is unique for addressing questions at the time and spatial scales relevant for change in arctic ecosystems.
N and P fertilization experiment plant species composition and diversity data for South of saddle, 1990 - 2000.
The effects of nitrogen, phosphorus, and nitrogen+phosphorus fertilization on alpine plant species composition and diversity in a dry and a wet meadow community were examined. A point-quadrat system was used to estimate the cover frequencies for each species in plots in the 2 communities on the south slope of Niwot Ridge. Treatments were N, P, N+P, and control. Observations were made once per year per plot over a period of several years. Diversity (Shannon-Weaver) indices were also calculated.
N and P addition experiment colonization data for Niwot Ridge from 2015 to 2019, yearly
In 2014 we established 20 experimental plots (25 x 25 cm) at four Snowbed Experiment sites (Arikaree, D1, Martinelli, and Soddie) in order to investigate the effect of nitrogen (N) and phosphorous (P) nutrient additions on plant colonization in snowbed areas with a recently diminishing persistence of summer snow cover. Plots were established in areas of persistent snow cover where there was only bare soil and no plants growing. Treatments included (1) control (no nutrient additions), (2) N addition, (3) P addition, and (4) N + P addition. At each site, plots were grouped into five blocks, with one of each of the four treatment plots present in each block (4 sites x 5 blocks x 4 treatments = 80 plots). Treatments were assigned randomly (without replacement) within blocks.
