To hear or not to hear: selective tidal stream transport can interfere with the detectability of migrating silver eels in a Tidal River

open access: yesAnimal Biotelemetry, 2023
Acoustic telemetry provides valuable insights into behavioural patterns of aquatic animals such as downstream migrating European eels (Anguilla anguilla), so called silver eels.

A Novel Framework to Predict Relative Habitat Selection in Aquatic Systems: Applying Machine Learning and Resource Selection Functions to Acoustic Telemetry Data From Multiple Shark Species

open access: yesFrontiers in Marine Science, 2021
Resource selection functions (RSFs) have been widely applied to animal tracking data to examine relative habitat selection and to help guide management and conservation strategies.

A Markov Chain state transition approach to establishing critical phases for AUV reliability [PDF]

open access: yes, 2011
The deployment of complex autonomous underwater platforms for marine science comprises a series of sequential steps. Each step is critical to the success of the mission. In this paper we present a state transition approach, in the form of a Markov chain,

High data rate acoustic telemetry [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1981
Four separate acoustic telemetry experiments were conducted during 1979 and 1980 off eastern San Clemente Island in water 1350 to 1450 m deep. In each experiment, telemetry originating near the seafloor was transmitted to receivers aboard a drifting surface ship which remained within 45° from vertically above the telemetry source.

Wireless recording of the calls of Rousettus aegyptiacus and their reproduction using electrostatic transducers [PDF]

open access: yes, 2008
Bats are capable of imaging their surroundings in great detail using echolocation. To apply similar methods to human engineering systems requires the capability to measure and recreate the signals used, and to understand the processing applied to ...

Acoustic telemetry system as a novel approach for evaluating the effective attraction of fish to artificial reefs

open access: yesFrontiers in Marine Science, 2023
Due to there being a lack of suitable approaches for evaluating the effectiveness of artificial reefs, two experiments were designed to examine the feasibility of acoustic telemetry, a rapidly developing method for tracking aquatic animals.

The African hind's (Cephalopholis taeniops, serranidae) use of artificial reefs off Sal Island (Cape Verde): a preliminary study based on acoustic telemetry [PDF]

open access: yes, 2011
The African hind Cephalopholis taeniops (Valenciennes, 1828) is one of the most important commercial demersal species caught in the Cape Verde archipelago. The species is closely associated with hard substrate and is one of the main attractions for SCUBA

Comparing acoustic and satellite telemetry: an analysis quantifying the space use of Chelonia mydas in Bimini, Bahamas

open access: yesRoyal Society Open Science
Passive acoustic and Argos satellite telemetry are common methods for tracking marine species and are often used similarly to quantify space use. However, data-driven comparisons of these methods and their associated ecological inferences are limited. To

Tracking crocodylia: a review of telemetry studies on movements and spatial use

open access: yesAnimal Biotelemetry, 2023
Crocodylians are top predators that play key ecological roles in aquatic ecosystems. As in other groups of large predators, crocodylian populations are often impacted by habitat loss, habitat degradation or direct exploitation for commercial purposes or ...
