Bi-class classification of humpback whale sound units against complex background noise with Deep Convolution Neural Network

, 2017
Automatically detecting sound units of humpback whales in complex time-varying background noises is a current challenge for scientists. In this paper, we explore the applicability of Convolution Neural Network (CNN) method for this task.

A Correspondence Between Distances and Embeddings for Manifolds: New Techniques for Applications of the Abstract Boundary

, 2011
We present a one-to-one correspondence between equivalence classes of embeddings of a manifold (into a larger manifold of the same dimension) and equivalence classes of certain distances on the manifold.

Indigenous resurgence in the Blue Economy: Relational values to guide kelp mariculture

People and Nature, EarlyView.
Abstract Decisions about how to use ocean spaces are increasingly attuned to issues of social equity, environmental sustainability and climate resilience, yet often bypass local governance, knowledge, values and thus objectives. To inform future decisions about kelp harvest and mariculture activities on the west coast of Canada, we co‐designed research

Whale-watching and Herring Fishing: Joint or Independent Production? [PDF]

The effects of "localized depletion" of a pelagic fishery (herring) on a non-extractive marine activity (tourism) are investigated. Proponents of the localized depletion theory claim that intense fishing effort can lead to areas that are unsuitable for ...

Dimensional Stability and Mechanical Performance of Thermally Conditioned High‐Heat Polylactic Acid Parts Produced by Fused Filament Fabrication

Polymer Engineering &Science, EarlyView.
Dimensional accuracy and tensile strength of high‐heat PLA parts printed by FFF as a function of printing temperature and annealing, highlighting the 210‐240°C window where geometry, UTS and model predictions are jointly optimized. ABSTRACT Additively manufactured high‐heat PLA parts must balance dimensional fidelity and tensile performance.

Population changes in a Southern Ocean krill predator point towards regional Antarctic sea ice declines

Scientific Reports
While foraging, marine predators integrate information about the environment often across wide-ranging oceanic foraging grounds and reflect these in population parameters.

HOWLish: a CNN for automated wolf howl detection

Remote Sensing in Ecology and Conservation, EarlyView.
Automated detection of wolf howls presents a great opportunity for large‐scale passive acoustic monitoring of wolf populations. Here we present HOWLish, a CNN trained for automated wolf howl detection, based on thousands of hours of soundscapes recorded in the wild.

The variability of muscle–blubber interface temperature with activity level in a captive Risso’s dolphin (Grampus griseus)

Animal Biotelemetry
Background To reduce heat loss underwater, marine mammals cover their bodies with insulation. Cetaceans in particular rely solely on blubber for insulation which has low conductivity.
