Environmental evidence for a pygmy blue whale aggregation area in the Subtropical Convergence Zone south of Australia
Abstract The importance of the Subtropical Convergence Zone south of Australia as a feeding area to the pygmy blue whale of the eastern Indian Ocean was investigated to better understand migration patterns and habitat use. A combination of satellite tagging studies during 2003–2005 and acoustic and...
