Federal sampler data for Black Sand experimental plots, 2018

This project is part of the Black Sand experiment to monitor effects of early snowmelt at Niwot Ridge. At each of five sites (Lefty, Soddie, Trough, East Knoll and Audubon) two 2x2 m plots were set up and two 3x3m plots were set up, with one of each size plot receiving 600 g/m2 black sand and one receiving 800 g/m2 of black sand. This portion of the black sand experiment was to look at snow depth and SWE using a federal sampler at each of the plots in 2018. We use an aluminum Standard Federal Snow Sampler to measure snow depth and snow water equivalent (SWE). This device, compared to traditional snow pit techniques, provides efficient measurement capabilities that are less disruptive to the snowpack. Manual Federal Sampler measurements provide high accuracy point data to determine the amount of water in the surrounding snowpack. With a high downstream reliance on water within the regional snowpack, our weekly measurements give a time series of SWE throughout the winter season, offering consistent and dependable information for water resource planning and preparation.
