A Look at Important Marine Areas in the U.S. Beaufort and Chukchi Seas: Ecologically rich places to protect in the Arctic Ocean [PDF]

, 2016
Sound decision-making about the future of the U.S. Arctic Ocean must include an understanding of how its marine ecosystems function. Although all areas of the U.S. Chukchi and Beaufort seas contribute to ecological integrity, some are especially vital to

Dependence Between Effort Offsets and Process Intensity in Generalized Models for Count Data: Spatial Models of Animal Abundance

Environmetrics, Volume 37, Issue 3, April 2026.
ABSTRACT Researchers often use offsets to control for variation in exposure or effort in GLMM‐style models for count data. In this paper, we study the case where effort is dependent on the underlying process of interest (e.g., Poisson intensity) and where inference focuses on prediction. We first examine a simple Poisson GLM, where we use simulation to

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

Frontiers 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

Concentrations of Polychlorinated Biphenyls (PCB’s), Chlorinated Pesticides, and Heavy Metals and Other Elements in Tissues of Belugas, Delphinapterus leucas, from Cook Inlet [PDF]

, 2000
Tissues from Cook Inlet beluga whales, Delphinapterus leucas, that were collected as part of the Alaska Marine Mammal Tissue Archival Project were analyzed for polychlorinated biphenyls (PCB’s), chlorinated pesticides, and heavy metals and other elements.

A High‐Accuracy TEC Model for Low‐Mid Latitudes Using a BWO‐Optimized CNN‐xLSTM Hybrid Model With Multi‐Instrument Data Fusion

Space Weather, Volume 24, Issue 4, April 2026.
Abstract The total electron content (TEC) in the ionosphere is strongly affected by solar activity and geomagnetic disturbances in mid‐ and low‐latitude regions, making it a major source of error in GNSS navigation and communication systems. To improve the prediction accuracy of ionospheric TEC, this study proposes a deep learning model—Beluga Whale ...

Navigating Cetacean Mitochondrial Genome Data: Identifying Coverage and Deficiencies in Public Repositories

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Genetic reference databases underpin a wide range of molecular approaches used to study cetacean biodiversity, including environmental DNA (eDNA), yet their reliability depends critically on data completeness, taxonomic accuracy, and metadata quality.

Skin microbiome of beluga whales: spatial, temporal, and health-related dynamics

Animal Microbiome, 2020
Background Host-specific microbiomes play an important role in individual health and ecology; in marine mammals, epidermal microbiomes may be a protective barrier between the host and its aqueous environment.

Abundance of harbor porpoise (Phocoena phocoena) in three Alaskan regions, corrected for observer errors due to perception bias and species misidentification, and corrected for animals submerged from view [PDF]

, 2010
Estimating the abundance of cetaceans from aerial survey data requires careful attention to survey design and analysis. Once an aerial observer perceives a marine mammal or group of marine mammals, he or she has only a few seconds to identify and ...
