SPRUCE S1 Bog and SPRUCE Experiment Location Survey Results, 2015 and 2020

This data set provides results from two horizontal and vertical surveys (2015, 2020) of SPRUCE experimental infrastructure and measurement locations on the S1 bog on the Marcell Experimental Forest and the SPRUCE experimental site within the S1 bog. Measurements, both horizontal and vertical, are made to the nearest ~3 mm (0.01 foot), such that the resolution of the measurements is ± 3 mm. The first survey was performed in July, August, and September 2015. The second survey was performed in September and October 2020. The same locations were surveyed in both years. Benchmarks were set at the entrance to each of the three transect boardwalks and then level loops were run inside and around the experimental plots to get the individual point horizontal and vertical coordinates. Selected points were surveyed in and around the 17 plots including: central wells, elevation standards, central towers, 0 m piezometers, wood planks attached to the belowground corral, and 8 points around the octagonal boardwalks. Note that not all plots have all of these features. Additional locations were surveyed across the S1 bog including: EM1, EM2, and EM3 wells, the Forest Service bog well, and the Test 6 piezometer.
