The hydrophone node at Orcasound (the home and laboratory of Dr. Val Viers) is located between Snug Harbor and Andrew's Bay, about 6 kilometers north of the Lime Kiln Lighthouse. Dr. Viers has completed many research projects, hydrophone deploments and repairs since he began working at this site in 2000.
Currently, there are two hydrophones at this site which sit 1 to 2 meters above the gravel bottom about 100 meters offshore. From there, cables travel over the rocky intertidal to a computer. Dr. Viers wrote custom software for the computer which automatically detects unusual sounds (like orcas) and measures the average sound levels for the area.
