Study was made of the vocal repertoires of three species of seals and sea lions which, until now, have been reported as not being very vocal under water. Sonograms of underwater vocalizations are presented for the gray seal and the harbor seal for the first time. In all cases, underwater vocalization occurred within a social context, and it was noted that many of the vocalizations emitted under water may also be emitted in air. 
In-air and underwater vocalizations of eastern Canadian harbour seals, Phoca vitulina
TLDR
In this study, seals produced an underwater roar vocalization closely resembling that produced by adult males during the mating season at other sites.
How small could a pup sound? The physical bases of signaling body size in harbor seals
TLDR
It is found that, while body growth puts anatomical constraints on how vocalizations are filtered by harbor seals’ vocal tract, no such constraints appear to exist on vocal folds, at least during puppyhood.
Underwater Acoustic Displays by Male Harbor Seals ( Phoca Vitulina ):Initial Results
TLDR
Underwater vocalizations have been studied for a number of the phocid pinnipeds and found that male Weddell seals have a larger, more complex repertoire than females, which they appear to use in underwater territorial displays during the breeding season.
Individually distinctive pup vocalizations fail to prevent allo-suckling in grey seals
TLDR
During the 1997 breeding season on the Isle of May, Scotland, vocalizations were recorded from grey seal, Halichoerus grypus, pups, and playback experiments revealed that mothers did not respond more to vocalizations of their own pups than to those of nonfilial pups.
Airborne Acoustic Communication in the Hawaiian Monk Seal, Monachus Schauinslandi
Acoustic communication is important in the social life of pinnipeds, but our knowledge of it is limited. Physical analyses of sound signals are unavailable for some species, and are scant for others
SENSORY BIOPHYSICS OF MARINE MAMMALS
TLDR
Methods for observation of sensory mechanisms are noted along with a discussion of other aspects of marine mammalBiophysics including vibrissal sensation and the biophysics of movement in a fluid environment.
The Underwater Soundscape at Gulf of Riga Marine-Protected Areas
Passive acoustic monitoring (PAM) is widely used as an initial step towards an assessment of environmental status. In the present study, underwater ambient sound recordings from two monitoring
AERIAL AND UNDERWATER VISUAL ACUITY IN THE CALIFORNIA SEA LION (ZALOPHUS CALIFORNIANUS) AS A FUNCTION OF LUMINANCE *
TLDR
Pinnipeds engage in some more or less spectacular activities that presumably depend on a variety of orientation skills, and no single set of internal or external receptor mechanisms would be relied upon as the exclusive, or even as the primary, basis of pinniped sensory orientation.
Underwater hearing sensitivity of a male and a female Steller sea lion (Eumetopias jubatus).
TLDR
The unmasked underwater hearing sensitivities of an 8-year-old male and a 7- year-old female Steller sea lion were measured in a pool, by using behavioral psychophysics, and hearing thresholds of the male were significantly higher than those of the female.
Underwater detection of tonal signals between 0.125 and 100 kHz by harbor seals (Phoca vitulina).
TLDR
The results suggest that under unmasked conditions many anthropogenic noise sources and sounds from conspecifics are audible to harbor seals at greater ranges than formerly believed.

The author spent two weeks in early February observing the breeding behavior of gray seals on the Basque Islands, Nova Scotia, the first such study earned out anywhere in the western Atlantic. The
Underwater Barking by Male Sea Lions (Zalophus californianus)
TLDR
Sonograms of barks from Zalophus were presented and it was thought that it was unlikely that these barks originated entirely in air and suggested that they were transmitted into the water by vibration of the submerged throat area while the sea lion's nose and mouth were in air.

Seals, Sea Lions, and Walruses: A Review of the Pinnipedia
TLDR
The pinnipeds, as a group, are world-wide in distribution although they are limited essentially to continental shores, islands, and polar ice fields in the breeding season, therefore, their distribution is essentially one-dimensional, comparable to that of alcids among birds, certain fishes and many marine invertebrates.
Barking, Dominance, and Territoriality in Male Sea Lions
TLDR
Experiments in which male sea lions were removed and reintroduced into a social group demonstrate that barking by larger males restricts movement and barking by other smaller males.
