Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating and Drying Research (DryPEHR): leaf C, N, delta-13-C, delta-N-15 2011-2019
This drying and warming experiment addresses the following questions: 1) Does ecosystem drying, warming and permafrost thaw cause a net release or uptake 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? 3) How do drying and warmign affect plant communities and ecosystem properties? We are answering these questions using a combined warming and drying experiment (DryPEHR), which is situated with the Carbon in Permafrost Experimental Heating Research (CiPEHR) project and located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. Warming treatment here refers to growing season air temperature warming (~1C) using open top chambers (OTC) combined with soil 'warming' using snow fences during the snow covered months. Drying is achieve using an automated pumping system that lowers the water table in the dry plots. Soil warming began in 2008; OTCs and drying in 2011. This data set includes foliar %C, %N, delta-13-C, delta-N-15 from green leaves collected in July and from senesced leaves collected in September.
Predicted carbon-13 NMR data of Natural Products (PNMRNP)
<p>PNMRNP is an SDF file that reports the structure, properties and classification of 211,280 natural products.</p> <p>The starting point of this work (January 2019) was <a href="https://github.com/oolonek/ISDB/tree/master/Data/dbs">ISDB</a> which contains csv files of the UNPD data base (Gu J et al., PLOS ONE 2013, 8, e62839, doi:10.1371/journal.pone.0062839) and which are packaged with the ISDB mass spectrometry fragmentation database (Allard PM et al., <em>Anal. Chem.</em> 2016, 88, 6, 3317-3323, doi: 10.1021/acs.analchem.5b04804).</p> <p>Starting from InChI strings of compounds, 2D structures with configuration data were produced mainly from the <a href="http://www.rdkit.org">RDKit cheminformatic toolkit</a>. <a href="http://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi">Pubchem</a> identifiers were searched for the compounds and used as keys to give names and synonyms to molecules. Carbon atoms in molecular structures were associated to <sup>13</sup>C NMR chemical shift values using <a href="https://nmrshiftdb.nmr.uni-koeln.de">nmrshiftdb2</a>. A three-level classification of compounds according to sub-structure presence is proposed. A compound may be classified as a terpene (level 1) as a sesquiterpene (level 2) and as an eudesmane (level 3).</p> <p>Version 2 of PNMRNP includes the classification of organic compounds according to <a href="http://classyfire.wishartlab.com">ClassyFire</a>.</p> <p>Version 3 of PNMRNP includes <sup>13</sup>C NMR chemical shifts calculated using ACD/Labs C+H NMR Predictors and DB.</p> <p> </p>

Soil Organic Carbon and Wetland Intrinsic Potential, Hoh River Watershed, WA, 2012-13
This dataset contains estimates of soil organic carbon stocks and wetland intrinsic potential (WIP) across the Hoh River Watershed in the Olympic Peninsula, WA, USA in 2012-2013. Estimates were derived from an equation based on wetland intrinsic potential and geology type (Stewart et al., 2023). Wetland intrinsic potential estimates the likelihood that that an area is a wetland using a random forest model built on vegetation, hydrology, and soil data (Halabisky et al., 2022). SOC estimates at 1 m and 30 cm, SOC standard deviations, and WIP are presented in Cloud-Optimized GeoTIFF (*.tif) format at 4-m resolution. Also included are 36 field observations of SOC collected from 2020-08-01 to 2022-06-29. These are contained in a comma separated (*.csv) file.
