Detailed Description

USGS Hawaiian Volcano Observatory and DOI Office of Aviation staff prepare the sampling mechanism (on blue tarp) and inspect the Unmanned Aircraft System (UAS) just before it took off to collect water from the Halema‘uma‘u crater lake. Brightly-colored flagging tape tied to a cable attached to the UAS indicated depth as the sampling tool was lowered into the water. The October 26, 2019, UAS water collection flight was conducted with permission from and in coordination with Hawai‘i Volcanoes National Park. DOI-OAS photo by J. Adams.
