Water Table Depth (WTD) NIMS grid Barrow, Alaska 2012
Water table depth (WTD) measurements were taken along the Networked Info-mechanical Systems (NIMS) grid in Barrow, Alaska during the summer of 2012. The NIMS grid is situated about 200 meters to the north east side of the ITEX dry sites. If a uniform representation of the water table within each plo...

Water table depth (WTD) measurements were taken along the Networked Info-mechanical Systems (NIMS) grid in Barrow, Alaska during the summer of 2012. The NIMS grid is situated about 200 meters to the north east side of the ITEX dry sites. 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, 2-3, 5-6, 7-8, 9-10, 11-12, 13-14, 15-16, 18-19, 20-21, 24-25, 26-27, 28-29, 30-31, 32-33, 34-35, 36-37, 38-39, 42-43, 44-45, 47-48, & 49-50.
