title: Barrow Atqasuk ITEX Plant

description: These files contain data representing the periodic plant measures of all species within each plot in a text tab delimited format. The data presented are phenological development (date of leaf bud burst, inflorescence emergence, flower bud, flower opening, flower withering, seed development, seed dispersal, and senescence), seasonal growth (length of leaf, and length of inflorescence), seasonal flowering (number of inflorescences in flower within a plot), occurrence of events (yes or no for leaf, inflorescence, bud, flower, and seed), and annual growth and reproductive effort (number of leaves, diameter of rosette, number of branches, maximum leaf length, number of inflorescences, maximum inflorescence length, number of buds, number of flowers, and number of seeds) collected weekly or yearly for all plant species during the summers of 1994-20XX for 48 plots (24 experiment open-top chamber plots and 24 control plots) at four sites (Atqasuk Wet Meadow, Atqasuk Dry Heath, Barrow Wet Meadow, and Barrow Dry Heath).

title: Water Table Depth (WTD) NIMS grid Atqasuk, Alaska 2013

description: Water table depth (WTD) measurements were taken along the Networked Info-mechanical Systems (NIMS) grid in Atqasuk, Alaska during the summer of 2013. The NIMS grid is situated about 50 meters to the south of 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 once a week 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: Snow Density ARCSS grid Barrow, Alaska 2010

description: Snow density measurements were taken towards the southwest corner of the Arctic System Science (ARCSS) grid at Barrow, Alaska. Cores were taken along a rough transect that ran from relatively shallow snow, through relatively deep snow to relatively shallow snow again. These cores were taken using 2 different sized diameter black PVC tubes that were hammered to ground level and then dug out to retrieve the snow core. The cores were placed in zip-loc bags and weighed after returning to the lab at BARC (Barrow Arctic Research Center). The Systems Ecology Lab (SEL) long depth probe was used (orange tape on the handle). Data have been corrected by subtracting 3cm from measurements made in the field to account for the missing tip of the probe. Using this field data a calculation of Snow Water Equivalence (SWE) was calculated for this area.

title: Kite Aerial Photography NIMS grid Toolik Lake, Alaska 2013

description: Aerial photographs of the Networked Info-mechanical System (NIMS) grid in Toolik Lake, Alaska were taken using a rig and kite system.
