A Real-Time Novelty Detector for a Mobile Robot
, 2000 Recognising new or unusual features of an environment is an ability which is potentially very useful to a robot. This paper demonstrates an algorithm which achieves this task by learning an internal representation of `normality' from sonar scans taken as

Journal of Zoology, EarlyView.The aim of this study was to evaluate the effect of acoustic stimulus on the behavioural and biochemical responses of two species of crayfish, Cherax destructor and Cherax quadricarinatus. Our results showed that exposure to noise significantly affects in both species motility parameters, agonistic interactions and acoustic signals emitted. In terms of

Sedimentology, EarlyView.ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

The use of the sonar complex when examining the lower surface of the ice
Российская Арктика, 2019 The article discusses the methodological issues of applying the sonar method to determine the shape of the lower surface of ice directly from the ice surface in the Arctic, as a complex solution for morphometric studies.

Sedimentology, EarlyView.ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.

Direct Assessment of Juvenile Atlantic Bluefin Tuna: Integrating Sonar and Aerial Results in Support of Fishery-Incident Surveys [PDF]
, 2014 There is a clear need for direct assessment approaches for Atlantic bluefin tuna (Thunnus thynnus, ABFT), including formulation of experimental designs and pilot surveys for abundance estimation.
