ABSTRACT:

Ion concentrations and precipitation amount were measured at 14 sites in the Salt Lake and Cache Valleys from December 2013 to February 2014. Sample collection was sporadic at several sites. The goal of this study was to identify land use impacts on nitrogen deposition to the iUTAH watersheds.

A subset of samples was analyzed for 15N and 18O of NO3 and 15N of NH4.

Methods and findings are described in the associated JGR-B manuscript

ABSTRACT:

Stream and groundwater samples were collected irregularly from August 2013 to November 2014 for analysis of major ions by ion chromatography. Sites included the Red Butte Creek GAMUT stations. Please see the published manuscript in Environmental Science & Technology for further details on sampling methods and analyses of these data.

ABSTRACT:

Here we report biogeochemical data from two sites in the Red Butte Creek watershed, Todd's Meadow in Red Butte Canyon, and Sage Pt. lawn on the U of Utah Canyon. GPS coordinates (WGS 84) for these sites are: 40.789, -111.796462 and 40.763, -111.830, respectively. Data were collected from 2013 - 14 in the context of a snow manipulation at both sites. See the attached document for details. Data include: surface soil moisture, temperature, and oxygen mixing ratios, extractable nitrogen (N) pools, total soil N, N in soil lysimeters, HCl-extractable soil iron, nitrate isotope composition, soil potential denitrification rates. A manuscript describing methods in detail is included.
