Monitoring of humpback whales in the Pender Bay, Kimberley Region, Western Australia
Information and learnings from two years of independent and shore-based humpback whale (Megaptera novaeangliae) surveys in the remote Kimberley region are presented. Systematic shore-based surveys were undertaken in 2009 and 2010 from the cliff top on the southern part of Pender Bay, Dampier Peninsu...
