So-called ‘bio-logging’ (also known as animal telemetry, biotelemetry, or animal-borne sensors) has been widely used to study marine animals that are difficult for humans to observe. In this study, we 1) review the types of sensors used, the animal taxa studied, and the study areas in marine bio-logging publications from 1974 to 2019; 2) introduce the main topics in behavioural and environmental marine bio-logging studies; and 3) discuss suggestions for future marine bio-logging studies. We expect that technological advances in new sensors will enhance the ability of both behavioural ecologists and oceanographers to explore animal movements, physiology and marine environments. In addition, we discuss future perspectives of bio-loggers to improve data acquisition and accuracy with longer battery life for applying bio-logging techniques to broader species. 2021-04-01T00:00:00Z https://repository.kopri.re.kr/handle/201206/11775 Title: Remote Recognition of Moving Behaviors for Captive Harbor Seals Using a Smart-Patch System via Bluetooth Communication Authors: Kim, Seungyeob; Jeong, Jinheon; Seo, Seung Gi; Im, Sehyeok; Lee, Won Young; Jin, Sung Hun Abstract: Animal telemetry has been recognized as a core platform for exploring animal species due to future opportunities in terms of its contribution toward marine fisheries and living resources. Herein, biologging systems with pressure sensors are successfully implemented via open-source hardware platforms, followed by immediate application to captive harbor seals (HS). Remotely captured output voltage signals in real-time mode via Bluetooth communication were reproducibly and reliably recorded on the basis of hours using a smartphone built with data capturing software with graphic user interface (GUI). Output voltages, corresponding to typical behaviors on the captive HS, such as stopping (A), rolling (B), flapping (C), and sliding (D), are clearly obtained, and their analytical interpretation on captured electrical signals are fully validated via a comparison study with consecutively captured images for each motion of the HS. Thus, the biologging system with low cost and light weight, which is fully compatible with a conventional smartphone, is expected to potentially contribute toward future anthology of seal animals. 2021-03-01T00:00:00Z
