Use of satellite imagery to estimate distribution and abundance of Cumberland Sound beluga whales reveals frequent use of a glacial river estuary

open access: yesFrontiers in Marine Science
Limiting disturbance in critical habitats is an important part of ensuring the well-being and sustainability of populations at risk, such as Cumberland Sound beluga whales (Delphinapterus leucas). Using non-disruptive Very High Resolution (VHR) satellite

Seismic moment tensor catalog for crustal earthquakes in the Cook Inlet and Susitna region of southern Alaska [PDF]

open access: yes, 2018
We determine moment tensor solutions for 53 earthquakes in southern Alaska, which include 9 in Beluga, 22 in Cook Inlet, and 22 in Susitna. The moment tensors were estimated using both the waveforms and the first-motion polarities.

Underwater Noise from Arctic Shipping: Impacts, Regulations and Recommendations [PDF]

open access: yes, 2017
Marine mammals, including whales, walrus, and seals, rely heavily on sounds for survival. The Arctic soundscape has long been shaped by their clicks and calls.

Do belugas send sound cues? -Experimental verification of blindfolded imitation among beluga-

open access: yesInternational Journal of Comparative Psychology
Dolphins are able to successfully coordinate their behavior using audio signals. Therefore, the current study tested whether or not belugas can use sound to exchange information in a cooperative task and verified the mechanisms of the transmission of information during trials. The subjects are two male belugas, Nack and Duke. Nack was trained to rotate

Noise levels and sources in the Stellwagen Bank National Marine Sanctuary and the St. Lawrence River Estuary [PDF]

open access: yes, 2005
Although ambient (background) noise in the ocean is a topic that has been widely studied since pre-World War II, the effects of noise on marine organisms has only been a focus of concern for the last 25 years.

Thirty years of herd focal follows reveal the functions of important habitats identified for the endangered St. Lawrence Estuary beluga

open access: yesEndangered Species Research
Identifying habitat functions is crucial for understanding how endangered populations such as the St. Lawrence Estuary (SLE) beluga Delphinapterus leucas use their environment, and for guiding effective conservation measures. Often, the only way to infer

Bester (beluga ♀ × starlet ♂) production and comparing their growth with beluga in Iran

open access: yes, 2009
Aquaculture for human consuming species is being considered as the first substitution of catching aquatic species due to increase of human population and decrease of wild aquatic stocks. In this study, the hybrid sturgeon Bester (female beluga x male sterlet ) was produced for the first time in Iran. Sperm of 1.35 kg male Acipenser ruthenus was used to

Generalized Perceptual Linear Prediction (gPLP) Features for Animal Vocalization Analysis [PDF]

open access: yes, 2006
A new feature extraction model, generalized perceptual linear prediction (gPLP), is developed to calculate a set of perceptually relevant features for digital signal analysis of animalvocalizations.
