The book focuses on the humpback whale's presence in Glacier Bay, detailing its significance as a summer habitat for these marine mammals. Written in the late 20th century, it likely reflects the growing concerns related to conservation and the impact of human activities on marine life. The report chronicles a series of observations detailing the declining presence of humpback whales in Glacier Bay during the late 1970s, attributing this shift to increased human activities, particularly rising vessel traffic in the area. It compiles data from various studies and meetings aimed at identifying the causes behind this trend, discussing potential management strategies to safeguard the humpback whale population. Key findings suggest a complex interplay between human disturbances and the natural behavior of the whales, with recommendations for further research and regulation of vessel activities to prevent further adverse impacts on whale behavior and habitats.
