Isotopes d2H and d18O in Alaskan ground, lake, and river water Dataset Description: <p>This dataset contains isotopic ratios&nbsp;d2H and d18O in Alaskan natural waters. &nbsp;The sampling location is included for each sample (lake, river, etc.) as well as the latitude and longitude of the sample site.</p>
<p>&nbsp;</p>
<p>&nbsp;</p> Methods and Sampling: <p>Discrete groundwater, lake, and river water samples were collected from Toolik Lake in September 2013 and July 2014.&nbsp; Groundwater samples were collected in all locations from freshly dug pits or temporary PVC well points of variable depth depending on the depth of the water table.&nbsp; All water samples were collected by submersible pump.&nbsp; Sample collection followed previously established methods as water was filtered to 0.45 microns into 2 mL gas chromatography vials.&nbsp; Samples were analyzed by the UC Davis Stable Isotope Facility on a Laser Water Isotope Analyzer V2 (Los Gatos Research Inc).&nbsp; Precision is typically ≤0.3 permil for d18O-H2O and ≤0.8 permil for dD-H2O.&nbsp; Values are reported relative to Vienna Standard Mean Ocean Water (VSMOW).</p>

EAGER: Subterranean Ground Water Discharge (SGD) in the Arctic as a Source of Atmospheric Methane? A Proof of Concept Study

EAGER: Subterranean Ground Water Discharge (SGD) in the Arctic as a Source of Atmospheric Methane? A Proof of Concept Study
<p><em>Extracted from the NSF award abstract:</em><br />
The major objective of this proof of concept study is to evaluate the contribution of Subterranean Groundwater Discharge (SGD) in the Arctic to the global methane budget. Methane is a potent greenhouse gas and large natural reservoirs exist in Arctic soils and permafrost. The working hypothesis is that methane released from thawing permafrost in the Arctic is transported via groundwater flow (above and below the permafrost layer) and enters the atmosphere via coastal waters and lakes. This source of methane may be realized as an important source of natural methane to the atmosphere and may provide a positive feedback to global warming.</p>
<p>The objectives of the study are:</p>
<p>1) To estimate the magnitude of subterranean groundwater discharge and associated methane flux into lakes and coastal waters in Alaska at three representative sites.</p>
<p>2) To evaluate methane evasion rates from the water column to the atmosphere.</p>
<p>3) To determine if the contribution of methane input from subterranean groundwater discharge to the global methane budget is significant, and if so</p>
<p>4) To use the preliminary data to design a more through research plan that will enable precise estimates of fluxes and provide a basis for global extrapolation of results such that the contribution of this source to current and future climate changes and the global methane budget will be possible.</p>
<p>The project will support a graduate student full time for two years. Undergraduate students in the ACCESS program and the California Alliance for Minority Participation in Science, Engineering and Mathematics program at UCSC will also participate in the proposed work. The PIs will work with COSEE Alaska to ntegrate this work in their outreach and education activities including teacher workshops, symposia, and work with local communities in Alaska.</p>
