Title: Soil Organic Horizon Exometabolomics Extracts and Soil Characteristics with Depth, Barrow, Alaska, 2014

Abstract

This dataset provides the results of physical and chemical characterization of soil organic horizons collected from the Barrow Environmental Observatory (BEO) near Barrow, Alaska. Four cores were collected 24-29 August 2014, two from a low-centered polygon center at area A and two from a high-centered polygon center at area B. The aboveground vegetation for one core at each site was primarily Carex aquatilis or Eriophorum angustifolium. Each organic horizon was sectioned into three operationally-defined 5-cm depths: top, middle, and bottom and extracted in triplicate resulting in 36 total samples for analysis by liquid chromatography-mass spectrometry to characterize the low molecular weight (LMW, less than 1000 Da) dissolved organic matter (DOM) across space. This dataset includes soil properties at each depth including soil gravimetric water content, total carbon and nitrogen, total organic carbon, root biomass data, untargeted measurements of LMW DOM availability (relative) with depth and between cores (vegetation and polygon type), and annotations for features that were significantly differentially-abundant with depth or between cores.
