QUANTIFYING THE ECOLOGICAL PROCESSES UNDERLYING COLLISIONS BETWEEN LARGE BALEEN WHALES AND LARGE SHIPS TO EVALUATE RISK
The marine environment is a major interface for human and wildlife conflict. Humans use the world’s oceans for activities ranging from military operations, tourism and recreation, commercial shipping and transport, and resource extraction. These activities have a variety of impacts on marine wildlif...

The marine environment is a major interface for human and wildlife conflict. Humans use the world’s oceans for activities ranging from military operations, tourism and recreation, commercial shipping and transport, and resource extraction. These activities have a variety of impacts on marine wildlife, from alteration of the acoustic environment, displacement, changes to behavior and movement to direct physical injury or death due to collisions with vessels. Increasing awareness of human-associated negative impacts has called for research aimed at understanding the specific effects and consequences of human activity and marine wildlife overlap. Large baleen whales are of particular research, conservation, and management interest. In past centuries, commercial whaling pressures decimated populations worldwide.
