00:00

02 Feb 2015: These offshore orca calls, recorded by an icListen HF hydrophone deployed at a depth of 1256 m at Ocean Networks Canada's Clayoquot Slope node, are a representative example of typical offshore orca vocalizations.

Northern right whale dolphins at Clayoquot Slope
 
00:00

19 January 2015: These patterned burst-pulse series, made by northern right whale dolphins, were recorded by the Ocean Sonics icListen high frequency hydrophone located at Ocean Networks Canada's Clayoquot Slope node www.oceannetworks.ca/installations/…layoquot-slope (depth: 1250 m). While northern right whale dolphins click frequently, they have not yet been observed making burst-pulse calls for long periods of time on the Ocean Networks Canada observatory.

Earthquake South of Port Hardy, Vancouver Island
 
00:00

27 March 2015: A magnitude 4.9 earthquake struck about 150km South of Port Hardy, Vancouver Island, shortly after noon on March 25th, 2015. This earthquake was detected by a variety of Ocean Networks Canada sensors, and was clearly recorded by the Ocean Sonics icListen low frequency hydrophone deployed at our Cascadia Basin node (http://www.oceannetworks.ca/installations/observatories/northeast-pacifi...).

The recording has been sped up by 10x to make the sound audible.

Possible Baird's Beaked Whale at Clayoquot Slope
 
00:00

14 September 2014: This unusual recording was captured by our Ocean Sonics icListen high frequency hydrophone at Clayoquot Slope (on the NEPTUNE Observatory). Experts who have listened to the recording are not able to identify the call with certainty, although the consensus is that it is probably a Baird's beaked whale. This uncertainty is due to the lack of information about Baird's beaked whale vocalizations. Baird beaked whales have not been studied as much as other whales as they are primarily offshore and tend to be elusive.

False Killer Whales in Cascadia Basin
 
00:00

30 August 2014: This is an example from approximately eight hours of false killer whale calls recorded during late August - early September 2014 on our NAXYS hydrophone at Cascadia Basin.

Offshore Orcas at Clayoquot Slope
 
00:00

24 January 2015: A recording of offshore killer whales. Offshore killer whales have been rarely recorded and these calls are not identifiable to any of the known call types for this population. This recording was captured by our Ocean Sonics icListen HF hydrophone (ID: 1253) deployed at Clayoquot Slope at a depth of 1250 m. Offshore orcas are the least known of the three orca ecotypes in the northeast Pacific Ocean. They range from California to Alaska and are typically seen 15 km or more offshore, though they are occasionally seen closer to shore.

Minke Whales in Cascadia Basin
 
00:00

24 October 2014: These minke whale calls were recorded by Ocean Networks Canada's broadband hydrophone located in Cascadia Basin: www.oceannetworks.ca/installations/…cascadia-basin (depth: 2660 m). The whales vocalized for over an hour, with most calls faint in the recording. The recording has been processed to enhance the calls.

Southern Resident K Pod Killer Whales at Fraser Delta
 
00:00

13 July 2014: This clear recording of Southern Resident orcas (killer whales) from the K pod was captured by our JASCO hydrophone array at the Fraser Delta in the Strait of Georgia.

Southern Resident orcas consist of only one acoustic clan, and are considered endangered. They spend much of the summer near and around San Juan Island, though their full range extends South to California and North to Haida Gwaii.

Earthquake near Vancouver Island
 
00:00

24 April 2014: A magnitude 6.6 earthquake struck off the coast of Vancouver Island at a depth of 11.4 km. The sound of this earthquake was clearly recorded by our icListen low-frequency hydrophone in Cascadia Basin (depth 2700 m), approximately 250 km away from the earthquake epicentre. In fact, it was so loud it saturated the input to this sensitive instrument.

This recording has been sped up 400% to make the earthquake audible. The crackling sounds were caused by the hydrophone saturating.
