ABSTRACT Little is known about the sounds produced by the Sei Whale Balaenoptera borealis and no recordings have been made in their presence in the Pacific Ocean. This research presents sounds recorded in the presence of Sei whales near the Hawaiian Islands in November, 2002. A total of 107 vocalizations, including two variations of low-frequency downswept calls, were measured. Two of these calls were sweeps from 100 Hz to 44 Hz, over 1.0 seconds. The second call type (n=105) consisted of low… 
Low-frequency vocalizations of sei whales (Balaenoptera borealis) in the Southern Ocean.
TLDR
Analysis of recordings from directional frequency analysis and recording sonobuoys in the presence of sei whales in the Southern Ocean in March 2013 identified both downsweep and upsweep calls, the first documented sei whale calls in theSouthern Ocean that are clearly less than 100 Hz.
Low frequency vocalizations attributed to sei whales (Balaenoptera borealis).
TLDR
Low frequency (<100 Hz) downsweep vocalizations were repeatedly recorded from ocean gliders east of Cape Cod, MA in May 2005 and were more similar to one another than to contemporaneous calls by other whales, suggesting that paired calls may be produced by the same animal.
Discovering sounds in Patagonia: characterizing sei whale (Balaenoptera borealis) downsweeps in the south-eastern Pacific Ocean
Abstract. The sei whale (Balaenoptera borealis) is one of the least known whale species. Information on sei whale distributions and its regional variability in the south-eastern Pacific Ocean are
Source level estimates for sei whale (Balaenoptera borealis) vocalizations off the Azores.
TLDR
Vocalizations are described from an encounter with two sei whales in April 2012 off Pico Island, Azores, using a combination of video range tracking (VRT) and acoustic methods to contribute to the understanding of this species' distribution and population identity.
Potential Bryde's whale (Balaenoptera edeni) calls recorded in the northern Gulf of Mexico.
TLDR
These results potentially identify a suite of previously undocumented calls from Bryde's whales, which could facilitate future passive acoustic monitoring efforts to better understand the population dynamics and status of this sub-population.
Fin Whale Song Patterns Shift Over Time in the Central North Pacific
Male fin whales sing by producing 20 Hz pulses in regular patterns of inter-note intervals. While singing, fin whales may also alternate the frequency ranges of their notes. Different song patterns
Listening for Whales at the Station ALOHA Cabled Observatory
The Station ALOHA Cabled Observatory (ACO) is an ocean-bottom observatory that allows continuous real-time monitoring of ocean processes including sounds produced by baleen whales. Baleen whales can
A complex baleen whale call recorded in the Mariana Trench Marine National Monument.
In fall 2014 and spring 2015, passive acoustic data were collected via autonomous gliders east of Guam in an area that included the Mariana Trench Marine National Monument. A short (2-4 s), complex
Long distance passive localization of vocalizing sei whales using an acoustic normal mode approach.
During a 2 day period in mid-September 2006, more than 200, unconfirmed but identifiable, sei whale (Balaenoptera borealis) calls were collected as incidental data during a multidisciplinary

Sei whale sounds recorded in the Antarctic.
TLDR
Recordings of low-frequency tonal and frequency swept calls were made near a group of four or five sei whales in waters west of the Antarctic Peninsula on 19 February 2003, finding that each call had different character and there was no temporal pattern in the calling.

SOUNDS FROM BRYDE, BALAENOPTERA EDENI, AND FINBACK, B. PHYSALUS, WHALES IN THE GULF OF CALIFORNIA
Low-frequency moaning sounds were recorded from Bryde whales, Ba/M!n.optera eden-i, off Loreto, Mexico, in the Gulf of California. These utterances averaged 0.4 s in duration with most of the sound
20-Hz pulses and other vocalizations of fin whales, Balaenoptera physalus, in the Gulf of California, Mexico.
TLDR
Gulf of California 20-Hz pulses were unique in terms of frequency modulation, interpulse sound levels, and temporal patterns, and may represent a regional stock revealed by their sound characteristics, a phenomenon previously shown for humpback whales, birds, and fish.
Songs of Humpback Whales
1) Humpback whales (Megaptera novaeangliae) produce a series of beautiful and varied sounds for a period of 7 to 30 minutes and then repeat the same series with considerable precision. We call such a
Vocalisations of Antarctic blue whales, Balaenoptera musculus intermedia, recorded during the 2001/2002 and 2002/2003 IWC/SOWER circumpolar cruises, Area V, Antarctica
TLDR
The results of this study suggest that the peak frequency of the 28 Hz vocalisations may be used as a diagnostic feature to aid in discriminating between Antarctic blue whales and pygmy blue whales in the field; however, examination of vocalisations in relation to group size and behaviour are necessary to understand the circumstances in which the 28Hz vocalisations are produced.
Geographic and seasonal variation of blue whale calls in the North Pacific
The call characteristics and distribution of blue whales in the North Pacific were examined by use of acoustic surveys. Two dis tinct vocalisation types have been previously attributed to blue whales
Passive acoustic methods applied to fin whale population density estimation
Assessing the size of cetacean populations in the open ocean has traditionally relied on visual surveys alone. The addition of acoustic monitoring can complement these surveys if reliable protocols

TLDR
This opportunistic survey has shown that acoustics is an effective means of studying this poorly understood, pelagic balaenopterid.
