Field recordings

Each piece carries its own recording, activated by that piece's toggle, descending as the installation does.

Surface

Humpbacks and Murrelets, recorded in lower Glacier Bay National Park and Preserve, Alaska. Source: US National Park Service. Recorded as part of Voices of Glacier Bay, a two year project by Richard Nelson and Hank Lentfer.

Under the surface

A composite of two sources. Base recording, humpback whale bubble-feeding and vocalizing, Glacier Bay National Park and Preserve, Alaska, from the US National Park Service, recorded as part of Voices of Glacier Bay by Richard Nelson and Hank Lentfer.

Layered with recordings from the Salish Sea Humpback Vocalization Catalogue by the Orcasound project, including recordings from Saturna Island on Boundary Pass, about 20km south of Galiano. First version of the catalogue created by Emily Vierling, 2022. Orcasound also runs live underwater hydrophone streams.

Orca vocalizations, likely from the PerenniAL Acoustic Observatory in the Antarctic Ocean (PALAOA), 2023. Recorded by Ilse van Opzeeland, Alfred Wegener Institute. Source: US National Oceanic and Atmospheric Administration, Sounds in the Ocean: Mammals.

Deep water

Bearded seal call. Institutional recordist: Cornell University, Cornell Lab of Ornithology, K. Lisa Yang Center for Conservation Bioacoustics. Source: US National Oceanic and Atmospheric Administration, Sounds in the Ocean: Mammals. More on bearded seals, whose habitat is arctic and sub-arctic.
