This product consists of multiple tabular datasets and associated metadata of water quality information related to rivers, streams, and lakes in the Yukon River watershed between 2014 and 2018. This data release is apart of the National Aeronautics and Space Administration (NASA) funded Arctic-Boreal Vulnerability Experiment (ABoVE) and is an assessment of water quality and greenhouse gas fluxes within the interior of Alaska. Sampling frequency varied across locations, with some sites sampled twice a year or more. Data consist of: organic and inorganic carbon related species, carbon dioxide and methane gas fluxes calculated from manual chamber measurements, nitrogen species, carbon isotopes, oxygen and deuterium...

Sample Analysis: Cation concentration data was obtained as a part of the beryllium isotope analyses. Samples collected from the Upper Geyser Basin were first treated in clean laboratory facilities at the University of New Hampshire following the methods laid out in the “Beryllium Isotope Data” portion of this data release. Following the hydrofluoric acid (HF) etches, and prior to Accelerated Mass Spectroscopy (AMS) analyses of 10Be, opal purity was assessed by measurement of major cation concentrations via inductively coupled plasma-optical emission spectrometry (ICP-OES) using a Perkin Elmer Optima 3300DV at the Analytical and Technical Services lab at SUNY College of Environmental Science and Forestry in Syracuse,...

Natural and anthropogenic changes in basin lake levels in the western U.S. expose saline, alkaline substrates that are commonly colonized by shrubs in the Chenopodiaceae. On a chronosequence of recently exposed substrates at Mono Lake, California, Sarcobatus vermiculatus has greatest biomass accrual, seed production, seedling establishment, and leaf N at younger sites where soils are extremely saline and alkaline. These field observations and an understanding of the role of N-containing compatible solutes in salinity tolerance of halophytes led to our prediction that Na and N interactions stimulate Sarcobatus performance. To test this, we grew Sarcobatus juveniles for 2 years in the greenhouse at 4 levels of NaCl...
