This audio montage consists of raw location recordings, with no added audio effects, tracing a research journey through Chile’s southernmost regions (Tierra del Fuego and Navarino Island) to the decommissioned radio station at Wulaia Bay. The piece weaves together diverse auditory traces from above and below the waterline, including the murmurs of weather and foliage, the acoustics of marine habitats, the whistling of piers, ground electricity, signals of satellites, earth-ionosphere echoes, reverberations of culturally modified trees and environmentally-situated linguistics. File tagging voice annotations and closed caption titles provide waymarks in diverse atmospheres and meandering encounters at earth’s southern expanse.
