The live feed shows the latest detections of right whales in Massachusetts Bay. Image captured on AMrch 15, Red whale icons indicate buoys that had detected a right whale call within the last 24 hours. Green circles are buoys with no right whale detections in 24 hours.

Research School. Unknown Feed. Professor Lars Bejder PhD, MSc, BSc Research Leader, Murdoch University Cetacean Research Unit MUCRU About me My main research interests fall into three categories: analysing and developing quantitative methods to evaluate complex animal social structures; evaluating impacts of human activity coastal development, tourism, habitat degradation on cetaceans; and fundamental biology and ecology, including assessing abundance and habitat use of marine wildlife.
