Underwater sound was recorded in one of the major coastal foraging areas for juvenile sea turtles in the Peconic Bay Estuary system in Long Island, New York. The recording season of the underwater environment coincided with the sea turtle activity season in an inshore area where there is considerable boating and recreational activity, especially during the summer between Independence Day and Labor Day. Within the range of sea turtle hearing, average noise pressure reached 110 dB during periods…

Temporal patterns in ambient noise of biological origin from a shallow water temperate reef
A systematic study of the ambient noise in the shallow coastal waters of north-eastern New Zealand shows large temporal variability in acoustic power levels between seasons, moon phase and the time
Underwater noise pollution in a coastal tropical environment.
Year-round variability of ambient noise in temperate freshwater habitats and its implications for fishes
TLDR
Comparison of these eco-acoustical data with a preceding study indicates that the auditory sensitivity in hearing specialists is affected by changes in ambient noise levels and spectra throughout a year and that this effect tends to be more pronounced in stagnant waters and the stream than at river sites.
Riders on the storm: loggerhead sea turtles detect and respond to a major hurricane in the Northwest Atlantic Ocean
TLDR
The movements and dive behavior of juvenile and adult-sized loggerhead sea turtles that were foraging in the Mid-Atlantic Bight as Hurricane Irene moved through the region were analyzed and recorded, demonstrating that loggerheads observe environmental changes to the entire water column, including during extreme weather events.
Variability in ambient noise levels and call parameters of North Atlantic right whales in three habitat areas.
TLDR
This study characterizes the ambient noise levels, including both natural and anthropogenic sources, and right whale upcall parameters in three right whale habitat areas and suggests that right whales may be responding to the peak frequency of noise, rather than the absolute noise level in their environment.
Soundscape of green turtle foraging habitats in Fiji, South Pacific
TLDR
This study investigates the soundscape at green turtle neritic foraging habitats in Fiji, South Pacific, with the aims of characterizing the contribution of each component and of comparing the levels of acoustic pressure among sites with different abundances of sea turtles.
Diversity in ambient noise in European freshwater habitats: noise levels, spectral profiles, and impact on fishes.
TLDR
Comparisons between the habitat noise types presented here and prior data on auditory masking indicate that fishes with enhanced hearing abilities are only moderately masked in stagnant, quiet habitats, whereas they would be considerably masked in fast-flowing habitats.

Assessing the effect of recreational scallop harvest on the distribution and behaviour of foraging marine turtles
Abstract The impact of fisheries on marine megafauna is widely known but most studies have focused on commercial fisheries, overlooking the effect of local recreational fisheries. This is

THE EFFECT OF VESSEL NOISE ON THE VOCAL BEHAVIOR OF BELUGAS IN THE ST. LAWRENCE RIVER ESTUARY, CANADA
During June-July 1991, we monitored the vocal behavior of belugas before, during, and after exposure to noise from a small motorboat and a ferry to determine if there were any consistent patterns in
Low-frequency ambient sound in the North Pacific: Long time series observations
Long-term statistics of ambient sound in an ocean basin have been derived from 2 years of data collected on 13 widely distributed receivers in the North Pacific. The data consist of single hydrophone
Reactions of bowhead whales, Balaena mysticetus, to seismic exploration in the Canadian Beaufort Sea.
TLDR
Tests with one 0.66-1 airgun showed that some bowheads move away from sources of strong seismic impulses even in the absence of boat noise, and that bowheads can detect the direction from which seismic impulses arrive.

Auditory Evoked Potentials of the Loggerhead Sea Turtle (Caretta caretta)
TLDR
Historically, ABRs have been used as a technique to evaluate audition and acoustic threshold, and the authors feel confident that the procedures developed here are both valid and effective when used on sea turtles.
Effects of low-frequency underwater sound on hair cells of the inner ear and lateral line of the teleost fish Astronotus ocellatus.
Fish (Astronotus ocellatus, the oscar) were subject to pure tones in order to determine the effects of sound at levels typical of man-made sources on the sensory epithelia of the ear and the lateral
Marine turtle reception of bone-conducted sound.
TLDR
Turtles are capable of receiving the low-frequency spectrum of the natal beach, which may serve as one of the cues in nesting returns and the involvement of the auditory system in bc responsivity is suggested.
Variation in humpback whale (Megaptera novaeangliae) song length in relation to low-frequency sound broadcasts.
Humpback whale song lengths were measured from recordings made off the west coast of the island of Hawai'i in March 1998 in relation to acoustic broadcasts ("pings") from the U.S. Navy SURTASS Low
Site fidelity and homing behavior in juvenile loggerhead sea turtles (Caretta caretta)
TLDR
The results of this study indicate that juvenile loggerheads exhibit fidelity to specific areas during summer months and possess the navigational abilities to home to these areas following forced displacements and long-distance migrations.
Effects of noise on growth and reproduction of Crangon crangon in rearing tanks
TLDR
Noise appears to increase aggression and mortality rate and to decrease food uptake in brown shrimp reared in acoustical conditions prevailing in a thermoregulated aquarium; these symptoms are extremely similar to those induced by adaptation to stress.
