OrcaSing Compilation

Multimedia highlights from OrcaSing 2003 - 2015. The older recordings of the SRKW (Southern Resident Killer Whales) were made by a custom model of the predecessor to the Cetacean Research™ C57 hydrophone. The 2015 recordings were made with our Cetacean Research™ SQ26-H1 hydrophone recording system view & listen

Humpback to Humpback
(direct comparison with competition)

A pair of recordings of humpback whale calls made out in the field using our Cetacean Research™ SQ26-MT (now the SQ26-H1) and a competing system; these directly compare our entry level hydrophone (the SQ26-08) to a competitor. We made a base broadband recording and also a couple spectra plots to show you the difference check out the comparison

Raccoons in the Pool!

One of our customers, a classical artist and recording engineer, employs a Cetacean Research™ C55 hydrophone as part of the equipment he uses to create new music. In this particular piece, the C55 and a DPA 8011 were used to record as a stereo pair. more about SWARMIUS method and music

Striped Dolphins in the Mediterranean

Recording of striped dolphins (Stenella coeruleoalba) made by Guillaume Marchais on a trip in the Mediterranean Sea with BDSF using the Cetacean Research™ SQ26-H1 hydrophone system - see larger photo

Ema K.'s Hawaiian Humpbacks

Humpback recordings made by Ema K. with the SQ26-MT portable underwater recording system in March 2009, west of Hawai'i Island's Kohala Coast - read Ema K's kudo

Humpbacks off the Kohala Coast

Humpback recordings made by Joe Olson with the SQ26-MTportable underwater recording system on 30 March 2007, west of Hawai'i Island's Kohala Coast - more about Joe's humpbacks

Springer (A73) Recordings

On 19 January 2002 in the Puget Sound waters between Seattle and Vashon Island, Joe Olson made what is believed to be the first recordings ever of an individual wild killer whale calf - more

Just how loud are the Washington State Ferries?

While recording Springer's vocalizations when she was an unidentified lone killer whale calf living in the middle of a very busy ferry lane, Joe made a separate recording of one of the Washington State ferries traveling between West Seattle and Vashon Island. This recording was made from a distance of 200m from the ferry on 19 January 2002 with a Cetacean Research™ C54 hydrophone - view plots & listen.

Sperm Whales as Sea Monsters?

Custom Cetacean Research Technology equipment was used for National Geographic Television's video "Sea Monsters: Search for the Giant Squid". This special was broadcast in February 1998 and won an Emmy for Best Sound, thanks to Cetacean Research™ hydrophones - more

Kingdome Demolition

On 26 March 2000, Seattle's Kingdome stadium was demolished.  Joe Olson lowered a Cetacean Research™ hydrophone into Elliott Bay and captured the underwater sounds of the gigantic steel and concrete structure crashing to the ground. The background sounds are from the hundreds of boats that gathered in Elliott Bay to witness the demolition. Notice the very low frequency echoes bouncing across the bay - also view plots.

Shilshole Samples

This pair of sound clips was made on 10 November 1998 with a Cetacean Research™ C20a2 hydrophone at Shilshole Bay Marina in Seattle, Washington - view plots & listen.

Orca Vocalizations while feeding

The L25 subpod of the Southern Resident Killer Whales spent an unusually long time in Dyes Inlet in November 1997. Cetacean Research Technology owner, Joe Olson, made this set of recordings of the orcas eating and vocalizing - more recordings of the L25 subpod while in Dyes Inlet

Navy SONAR from the USS Shoup

On 5 May 2003, the U.S. Navy Vessel "Shoup" DDG-86 Guided Missile Destroyer was operating its AN SQS - 53c mid range SONAR in Haro Strait between San Juan Island, WA and Vancouver Island, BC. The sounds of the SONAR were detected by the hydrophones of many scientists and whale watch operators working in the strait that day. The orcas of J pod were also in the area and were exhibiting very disturbing behavior while the SONAR was active.

This is a recording of two consecutive sonar pings detected by two hydrophones from Dr. Val Veirs' array on the west side of San Juan Island.

Hydrophone Duet with Ganges River Dolphins

In March and April 2003, Cetacean Research Technology President, Joe Olson, traveled to India and Bangladesh to record Ganges river dolphins and look for evidence of blue whales in the northern Bay of Bengal. This recording of Ganges river dolphins is from the Vikramshila Gangetic Dolphin Sanctuary near Bhagalpur, India. The recording was made with a Cetacean Research™ C54 hydrophone placed underwater and a Sennheiser e835S microphone in the air. The ultrasonic buzzing sounds from the dolphins are only audible to the human ear because they were so loud that they overloaded the hydrophone’s internal preamplifier, causing distortion that we can hear. The rhythmic sounds in the background are from fish.

Paul Knapp's Humpbacks singing in the Caribbean

These MP3 sound clips were recorded by Paul Knapp, Jr. on 14 February 1992 in the Caribbean. Each recording is of humpback whale songs. These recordings predate Cetacean Research Technology thus do not use our hydrophones, but they are really cool anyway.
