Colors of Lake Tahoe
This work is the result of a collaboration with Tahoe Environmental Research Center (TERC) scientists at the University of California, Davis.
The circle of color on each of these works is a pigment-based archival print, generated by data taken by scientists monitoring the health of Lake Tahoe. The prints represent as faithful a translation from the numerical measurements to printed color (at the base of the gradation) as is currently possible. As such, they serve as a objective record of the exact hues of the Lake and are time-stamped with the year, month, date, and 24-hour time of capture.
Each print is overlaid with an analog counterpoint— a hand drawn original graphite sketch featuring Tahoe scenery. Some also focus on a particular animal, or plant that is part of Tahoe’s ecology. These hand renderings also serve to highlight interconnectivity— the artist and viewer alike connect to the subject, and are a reminded of the uniquely human role in creating harmony or disruption in the earth’s ecological systems.
Scientists with UC Davis Tahoe Environmental Research Center (TERC) took measurements of the Lake’s color between 2012 and 2016 having tethered hyperspectral radiometers to the NASA-JPL Buoy TB3 (39°06’37”N 120°04’31”W) which were anchored 500 meters deep. The equipment measured the amount of light leaving the Lake was positioned at 12 and 5 meters below the surface. The scientists extrapolated the surface color from these measurements. The conversion of spectral measurements to print is described here so that future measurements may also be printed or compared visually.
For the Emerald Bay pieces in this series, the color measurements were taken manually at Emerald Bay by TERC researcher, Dr. Shohei Watanabe, for a project done in conjunction with Université Lavalin Quebec and show the stunning greens that are created by runoff of decomposed organic matter from the plants surrounding the Bay.
Many factors affect the Lake’s color, like its clarity and temperature, and levels of chlorophyll. Information on the ecological complexities of Lake Tahoe can be found here: terc.ucdavis.edu
