METHODOLOGICAL INFORMATION
--------------------------


1. Description of methods used for collection/generation of data: 

Data collection was performed using standard procedures as described in these publications and links to operation manuals:

Cunningham, W.L., and Schalk, C.W., comps., 2011a, Groundwater technical procedures of the U.S. Geological Survey, GWPD 3ÑEstablishing a permanent measuring point and other reference marks: U.S. Geological Survey Techniques and Methods 1ÐA1, 13 p. 
Freeman, L.A., Carpenter, M.C., Rosenberry, D.O., Rousseau, J.P., Unger, Randy, and McLean, J.S., 2004, Use of submersible pressure transducers in water-resources investigations: U.S. Geological Survey Techniques of Water- Resources Investigations, book 8, chap. A3, 50 p.

http://novalynx.com/store/pc/255-100-Analog-Output-Evaporation-Gauge-p802.htm
SkyTEM: Flight Profiles 1-4 were collected on 9/19/2013, Profiles 5-15 were collected on 9/20/2013, Profile 16 was collected on 9/26/2013. Time-domain airborne electromagnetic data collected by the HydroGeophysics Group (HGG) of Aarhus University. Amount of data collected: 184 line-km Instrumentation: SkyTEM 304L - 60 Hz

Surface NMR: Surface NMR data were acquired following the methods established in Parsekian et al., 2013.

Parsekian, A. D., Grosse, G., Walbrecker, J. O., MŸller?Petke, M., Keating, K., Liu, L., ... & Knight, R. (2013). Detecting unfrozen sediments below thermokarst lakes with surface nuclear magnetic resonance.ÊGeophysical Research Letters,Ê40(3), 535-540.



2. Methods for processing the data: 

A. SkyTEM: The SkyTEM data were processed using Aarhus Workbench. Please see the following thesis for details:

Armstrong, Ryan. 2015. Airborne electromagnetic data in a complex environment: identifying bedrock structure and Quaternary deposition. Thesis (M.S.)--University of Wyoming, 2015. 

B. Surface NMR: These data were processed and saved as inverted (INV) textfiles using MRSMATLAB and a bootstrapping algorithm to estimate uncertainty.

MŸller-Petke, M., Braun, M., Hertrich, M., Costabel, S., & Walbrecker, J. (2016). MRSmatlabÑA software tool for processing, modeling, and inversion of magnetic resonance sounding data. Geophysics, 81(4), WB9-WB21.

Parsekian, A. D., & Grombacher, D. (2015). Uncertainty estimates for surface nuclear magnetic resonance water content and relaxation time profiles from bootstrap statistics.ÊJournal of Applied Geophysics,Ê119, 61-70.

C. Bathymetric data. Depth information were consolidated into a file, by lake, which was then krigged and constrained to the boundaries of the lake. For example, at FL the files Fishhook062915.shp, Fishhook7X062915corDepth.shp, and FishhookWade062915.shp contain independent depth measures that were combined into a single file. The krigging output was constrained to the lake boundary identified in Fishhook_Outline_2mBuff.shp. For more details, including the script used to generate the bathymetric maps, please contact Jason Mercer (jmercer4@uwyo.edu).




3. Instrument- or software-specific information needed to interpret the data:

A. .wsl files must be read using the free software package Win-Situ 5 produced by: 
	In-Situ Inc.
         118 East Columbia River Way 
         Bingen, Washington 98605


B. Evaporation was measured using NovaLynx Class A evaporation pan and NovaLynx 255-100 Analog Output Evaporation Gauge.


        C. Water level was measured using In-Situ Level Troll 500 Data Logger.



4. Standards and calibration information, if appropriate:

N/A


5. Environmental/experimental conditions:

Various


6. Describe any quality-assurance procedures performed on the data:

Visual quality-assurance procedures were performed on all data to ensure consistency and to identify erroneous values of evaporation and change in water level due to freezing conditions.

Geophysical data were visually inspected for errors and spurious noise.


7. People involved with sample collection, processing, analysis and/or submission:

Those listed in the author section as well as Benjamin Kraashaur (UW) and Carl Legleiter (USGS).
