(formerly Quantum Spatial, Inc.), to conduct airborne thermal infrared and three-band red, green, blue surveys and produce the longitudinal stream temperature profiles and imagery mosaics. The Tulalip Tribes used these funds and in-kind contributions to enter a Joint Funding Agreement with the U.S. Geological Survey (USGS, 20YGJFA30081, with two amendments) to conduct float surveys, analyze and interpret data from the thermal infrared and float surveys, and produce a data release along with this report (Restivo and others, 2023).
