Habitat associations of cetaceans and seabirds in the tropical eastern Indian Ocean, Browse Basin, Australia (2008)
There is an increasing demand for integrated pelagic surveys to support ecosystem-based management of marine environments and their associated marine life. The Browse Basin in the tropical eastern Indian Ocean was surveyed using ship line transects to determine habitat associations of cetaceans and...
