  • This dataset relates to statistical models of killer whale (Orcinus orca) occurrence in the Bremer Sub-Basin developed from vessel-based and aerial survey data collected between 2015 and 2017. Further information can be found in: Salgado-Kent C, Parnum I, Wellard R, Erbe C, Fouda L. 2017. Habitat preferences and distribution of killer whales (Orcinus orca) in the Bremer Sub-Basin, Australia. Report to the National Environmental Science Programme Marine Biodiversity Hub (CMST 2017-15), 37 p.

  • Long-term passive acoustic observations were made at the edge of the continental shelf south of Bremer Bay, Western Australia, from February 2015 to February 2016, in order to assess seasonal patterns in the presence of various baleen and toothed whales around the Bremer Canyon/Marine Park. Further information is available in: Gavrilov A, Erbe C. 2017. Assessment of marine megafauna found at the edge of the continental shelf off Bremer Bay using passive acoustic observations. Report to the National Environmental Science Programme Marine Biodiversity Hub (CMST 2017-3), 35 p.

    This dataset describes visual sightings of marine megafauna (whales, dolphins and sharks) obtained during a series of dedicated aerial surveys conducted as part of a NESP Marine Biodiversity Hub project within and around the Bremer Marine Park, southern Western Australia. The data reflect 25 hours of observer effort (on transect), and 62 sightings of four identifiable species, including killer whales (Orcinus orca), sperm whales (Physeter macrocephalus), long-finned pilot whales (Globicephala melas), and bottlenose dolphins (Tursiops sp.). Numerous unidentified cetaceans and sharks were also seen. For more information, see: https://www.nespmarine.edu.au/project/ep2-surveying-marine-life-canyons-bremer-bay

  • This dataset relates to deployments of pelagic stereo-BRUVS conducted by the University of Western Australia within and to the west of the Bremer Marine Park in February/March 2017. The survey was undertaken to provide a baseline assessment of the pelagic assemblages occurring in the region as part of the NESP Marine Biodiversity Hub Emerging Priorities Project #EP2 (https://www.nespmarine.edu.au/project/ep2-surveying-marine-life-canyons-bremer-bay). A total of 791 individuals from 13 taxa were identified.
