title: Snow Melt Transect ARCSS grid Barrow, Alaska 2012

description: A 200 meter snow melt transect was chosen within the Arctic System Science (ARCSS) grid in Barrow, Alaska. ARCSS grid coordinates are labeled A thru K and 1 thru 11 for each N-S and E-W row of markers respectively. Transect begins 2 meters west of ARCSS grid point D09 and extends south ending 2 meters west of ARCSS grid point F09. Depth measurements were taken at every 2 meters along the transect on the east side of the transect to avoid any disturbances. The University of Texas at El Paso Systems Ecology Lab (SEL)'s Circumpolar Active Laery Monitoring (CALM) depth probe was used for the measurements. Location of the snow melt transect was chosen using ArcGis tools.

title: Water Table Depth (WTD) NIMS grid Atqasuk, Alaska 2011

description: Water table depth (WTD) measurements were taken along the Networked Info-mechanical Systems (NIMS) grid in Atqasuk, Alaska during the summer of 2011. The NIMS grid is situated about 50 meters to the south of the The International Tundra Experiment (ITEX) dry site. If a uniform representation of the water table within each plot was visible, then a WTD tube was placed there to measure the change in water table throughout the season. For instance if the plot was half saturated and half dry, then that plot was skipped and no tube was placed there. The exact location of WTD tubes are as follows: Between meters 0-1, 3-4, 5-6, 7-8, 9-10, 11-12, 13-14, 15-16, 17-18, 19-20, 21-22, 23-24, 25-26, 32-33, 34-35, 36-37, 38-39, 40-41, 42-43, 44-45, 46-47 & 48-49. A total of 22 WTD tubes were installed into the NIMS grid in Atqasuk. Measurements were made every few days during the summer snow free period between mid June and mid August. WTD was calculated as the difference between the depth (cm) of the water table above or below the measuring tube (- Values = water above tube, + Values= water level below the height of the tube) and the height of the top of the measuring tube above the ground level. Measurements were not made (NA in data sheet) if there was persistent snow cover, interference or disturbance from other experimental infrastructure, or if water table depth tubes were dry to the upper surface of the permafrost.

title: Spectral Reflectance Measurements NIMS grid Atqasuk, Alaska 2012

description: Spectral measurements were taken at each meter of the Networked info-mechanical system (NIMS) grid in Atqasuk, Alaska during the summer of 2012. The NIMS grid is situated about 50 meters to the south of the International Tundra Experiment (ITEX) dry sites. Measurements were taken from the edge of each white board located at each meter aimed at the plots. The instrumentation used was a Unispec dual channel (DC) spectrometer with fiber optics as sensors. A manfrotto tri-pod with an arm attachment was used to hold the fibers and sensors in place while taking the spectral measurements. The arm had 2 bubble levels to assist in keeping the sensors as level as possible. The calculated foot print cover is about 50-60 cm using a tri-pod height of 1.62 meters. The sensor angle for each scan is 20 degrees. Extra reference scans were taken on a 100 percent reflective white board surface.

title: Spectral Reflectance Measurements ARCSS grid Barrow, Alaska 2011

description: Spectral measurements were taken on a 30 plot subset within the Arctic System Science (ARCSS) grid in Barrow, Alaska during the summer of 2011. Spectral measurements were taken from the north eastern most corner of each plot. The subset is located from D2-D7 & H2-H7 within the 1 km^2 ARCSS grid. The instrumentation used was a Unispec dual channel (DC) spectometer with fiber optics as sensors. A manfrotto tripod with an arm attachment was used to hold the fibers and sensors in place while taking the spectral measurements. The arm had 2 bubble levels to assist in keeping the sensors as level as possible. The calculated foot print cover is about 50-60 cm using a tripod height of 1.62 meters. The sensor angle for each scan was 20 degrees. Extra reference scans were taken on a 100% reflective white board surface. Some plots contain crosshairs that are used for point framing purposes and might have an effect on the reflectivity of each scan. Therefore, an extra scan was taken adjacent to each plot on the west side.
