Techniques for cetacean-habitat modeling
Cetacean-habitat modeling, although still in the early stages of development, represents a potentially powerful tool for predicting cetacean distributions and understanding the ecological processesExpand

Habitat-based spatial models of cetacean density in the eastern Pacific Ocean
Many users of the marine environment (e.g. military, seismic researchers, fisheries) conduct activities that can potentially harm cetaceans. In the USA, Environmental Assessments or EnvironmentalExpand

Re-analysis of Gray Whale Southbound Migration Surveys 1967-2006
Between 1967 and 2007, 23 seasons of shore-based counts of the Eastern North Pacific (ENP) stock of gray whales (Eschrichtius robustus) were conducted throughout all or most of the southboundExpand

Abundance and densities of beaked and bottlenose whales (family Ziphiidae)
Estimating the abundance and density of beaked whales is more difficult than for most other cetacean species. Consequently few estimates appear in the published literature. Field identification isExpand

Spatial models of delphinid (family Delphinidae) encounter rate and group size in the eastern tropical Pacific Ocean
We use temporally dynamic environmental variables and fixed geographic variables to construct generalized additive models to predict delphinid (family Delphinidae) encounter rates (number of groupsExpand

4. Biologically Important Areas for Selected Cetaceans Within U.S. Waters – West Coast Region
In this review, we combine existing published and unpublished information along with expert judgment to identify and support the delineation of 28 Biologically Important Areas (BIAs) in U.S. watersExpand

Ziphius cavirostris) and Mesoplodon beaked whale population density from habitat characteristics in the eastern tropical Pacific Ocean
Temporally dynamic environmental variables and fixed geographic variables were used to construct generalised additive models to predict Cuvier’s ( Ziphius cavirostris) and Mesoplodon beaked whaleExpand

Seasonal spatial patterns in seabird and marine mammal distribution in the eastern Chukchi and western Beaufort seas: Identifying biologically important pelagic areas
Abstract The Chukchi and Beaufort seas are undergoing rapid climate change and increased human activity. Conservation efforts for upper trophic level predators such as seabirds and marine mammalsExpand

Alaska marine mammal stock assessments, 2016.
NOTE – December 2015: In areas outside of Alaska, studies of harbor porpoise distribution have indicated that stock structure is likely more fine-scaled than is reflected in the Alaska StockExpand
