Current Activities

Peter Corkeron has led the large whale research program at the Northeast Fisheries Science Center since 2011. The primary focus of the large whale research program is using science to assess the status as well as the anthropogenic and ecological drivers affecting North Atlantic right whales. The program is primarily based on aerial and vessel-based surveys of large whales through the waters of the northeastern US EEZ. It also includes close collaboration with colleagues in the Passive Acoustics group in Protected Species Branch, and with external partners in the local research community, particularly at the Woods Hole Oceanographic Institution and the New England Aquarium.

The remit of the large whale research program also covers other large whales, particularly humpbacks. Peter's work also includes assessing the effects of noise on large whales, developing new technology to enhance our understanding of whales' behavior and ecology, and applying these technologies to improve conservation outcomes for whales. He occasionally finds time to have fun with R.

Peter serves on the editorial boards of Marine Ecology Progress Series and Tourism in Marine Environments. He is a member of the World Conservation Union's (IUCN) Cetacean Specialist Group and a charter member of The Society for Marine Mammalogy.

Background

Peter's PhD was on the ecology of inshore dolphins in the waters off Brisbane, Queensland. Awarded by the University of Queensland in 1989, it was the first Australian PhD on the biology of living cetaceans. In 1988, Peter started another research program, on the behavior of humpback whales in Hervey Bay, Queensland, assessing the effects of the nascent whale-watching industry there. This science underpinned the creation of the world's first Marine Protected Area established to manage whale-watching, in 1989. At the same time, he maintained an active program on inshore dolphins in Moreton Bay, including research leading to the establishment of the interaction program with free-ranging dolphins at Tangalooma.

By 1990, he had moved to the University of Sydney, where, with Prof. Michael Bryden, he established what was then the premier cetacean research group in Australia. This included further work on inshore dolphin ecology and acoustics; humpback whale abundance estimation, behavior and movement ecology; and southern right whale population biology and behavior, including membership of the committees of PhD and MSc students. The right whale program that Peter started continues today as The Great Australian Bight Right Whale Study. Peter was also heavily involved in developing the original research program for the Australian Marine Mammal Research Centre, now part of the Marine Science Centre at Taronga Zoo. In early 1994, Peter survived a near-fatal assault.

While recovering from serious injuries, he moved to James Cook University in Townsville, Queensland, and worked on dugong abundance estimation. Building from his PhD work on humpback dolphins, Peter had identified two species of inshore tropical dolphins (now known as Australian humpback and Australian snubfin dolphins) as a particular conservation concern. While a James Cook Postdoctoral Fellow, he established a research program on the population biology, behavior and acoustics of these species, and restarted his dolphin research program in the waters off Brisbane. After his postdoc, he continued to develop his research group while a lecturer on contract, ran courses on coastal zone management, marine wildlife management and environmental science, and supervised PhD and MSc students. He also maintained his interests in the effects of tourism on marine wildlife, the evolutionary ecology of baleen whale ranging behavior, and even dabbled in work on fruit bats and wallabies.

In 2000, Peter moved to Tromsø, Norway to take up a position with the marine mammal group in the Norwegian Institute of Fisheries and Aquaculture Research, which became the Tromsø lab of the Norwegian Institute of Marine Research. There, he worked primarily on the population biology of phocid seals. Fieldwork took him to Svalbard, Jan Mayen and throughout northern Norway. In 2004, he quit his position in response a new policy introduced by the Norwegian government, that abused the concept of Ecosystem-Based Fisheries Management to justify culling marine mammals.

Moving with his family to the USA, over the next few years Peter had adjunct appointments with the Cornell Lab of Ornithology, the New England Aquarium, and the Woods Hole Oceanographic Institution. His diverse body of work over this period included running dugong surveys in Qatar, fieldwork on baleen whales in Oman, and writing on the "marine mammals eat fish" issue for conservation groups. In 2010, he spoke before a US Congressional subcommittee on "Marine Mammals In Captivity: What Constitutes Meaningful Public Education?". In his spare time, he wonders if people read these blurbs to the end.
