David Barclay presents a narrative mix assembled from a collection of underwater sounds collected over the last twenty years. Some recordings were made in impossibly remote places; deep ocean trenches, hydrothermal vent fields, or under the arctic ice, while others are from more familiar urban rivers, harbours and beaches.

The sounds are given a break from their usual analysis, where quantitative information about the ocean and its inhabitants is uncovered, and instead allowed to be enjoyed as they are.

David R. Barclay is a professor in the Department of Oceanography at Dalhousie University in Halifax, Nova Scotia. His research is centered on modeling and measuring the spatial and temporal properties of ambient noise in the ocean in an effort to study the natural mechanisms that generate underwater sound and the properties and variability of the oceanographic environments through which sound propagates. He has made recordings in the Bay of Fundy, at the bottom of the Mariana Trench, and along the length of the Mississippi.
