Examining distribution patterns of foraging and non-foraging sperm whales in Hawaiian waters using visual and passive acoustic data

Frontiers in Remote Sensing, 2022
Following the end of over a century of intensive commercial whaling in 1986, the monitoring and assessment of sperm whale populations is essential for guiding management and conservation decisions for their recovery.

Exploring variability in the diet of depredating sperm whales in the Gulf of Alaska through stable isotope analysis [PDF]

Royal Society Open Science, 2020
Sperm whales interact with commercially important groundfish fisheries offshore in the Gulf of Alaska (GOA). This study aims to use stable isotope analysis to better understand the trophic variability of sperm whales and their potential prey, and to use ...

Sperm whale presence observed using passive acoustic monitoring from gliders of opportunity

Endangered Species Research, 2020
Habitat use by the endangered Mediterranean sperm whale subpopulation remains poorly understood, especially in winter. The sustained presence of oceanographic autonomous underwater vehicles in the area presents an opportunity to improve observation ...
