New Research on Local Marine Mammal Strandings
posted 06/29/04
For the past 20 years, The Whale Museum has administered the San Juan County Marine Mammal Stranding Network. Morgan Sternberg, an undergraduate honors student at the University of Washington, recently analyzed 20 years of marine mammal stranding data from San Juan County. Working with the SeaDoc Society, Whale Museum and researchers at the University of Washington, Sternberg was able to determine where in the county marine mammals are most likely to strand. This information will help increase the number of carcasses collected, which are used to learn more about the biology and diseases of these animals. In Sternberg's research she noticed marine mammals tend to strand more often on beaches facing west and south. Beaches facing between west and south accounted for nearly 67% of all marine mammal strandings in San Juan County. Sternberg also noticed patterns of strandings based on the slope and fetch of the beach: strandings tended to occur more often on beaches with a gradually declining slope and a fetch of over 14,000 feet. The fetch of a beach is distance that wind and waves can travel between the beach and the nearest geographical obstruction. Interestingly, there was a correlation between Sternberg's research and findings by Dr. Terrie Klinger of the University of Washington who recently conducted research on currents throughout the region. Dr. Klinger used drift cards that were dispersed throughout the county and later retrieved on beaches throughout the region by beachcombers. Sternberg found that in many ways, marine mammal strandings and drift cards, land on beaches with similar directional orientation, slope, and fetch. If you find a sick or dead marine mammal on the beach, do not touch it. Instead, mark the location and call the stranding network's toll free hotline (1-800-562-8832). A network representative will instruct you on how to proceed. Seals and sea lions may "haul out" onto shore as a normal behavior throughout year and may not be in distress at all. It is important to keep your distance from the animal because human interaction may further complicate the situation. Cetaceans (whales, dolphins, and porpoises) should never be ashore and should be reported immediately. Number of whale necropsies will increase worldwideposted 05/18/04
The necropsy protocol will be finalized this week. "It's been used three times in the last month. Hopefully we will learn a lot in the next few years," Gaydos told participants at a whale symposium on May 15, 2004 in Friday Harbor. "The idea is to have free information sharing." If researchers don't have funds to conduct lab tests on samples from the deceased whales, there are labs which have agreed to do the tests for free. Currently researchers only know of 16 pathogens which affect whales. Gaydos noted researchers have found 190 pathogens which affect elk. There may be diseases which affect the reproductive ability of killer whales. If there are, the projected population rates would need to be revised, he said. "The idea behind it is to get as much information we can as fast as we can," Gaydos said. The protocol will likely be published as a NOAA technical document. Information about the program will also be available on the SeaDoc Web site. More than $1 million raised locally for researchposted 12/19/03 A recently completed study showed that within the Puget Sound/Georgia Basin marine ecosystem, over 62 species are listed as threatened, endangered, or are candidates for listing. This and other troubling issues have led some to describe the marine ecosystem as being in decay, a term first coined to describe the world-wide unraveling of tropical rainforest ecosystems. Research projects funded this year address recovery of declining rockfish, Pacific herring, and white-winged and surf scoters. Additionally, a project also was funded to investigate historical tribal knowledge of marine fish and wildlife and the tribal implications for using protected areas as a tool for recovering species. Within the region, SeaDoc Society-funded research results are being actively used by local marine resource committees, state agencies, tribes, and federal agencies such as NOAA Fisheries and the U.S. Fish & Wildlife Service. The US Fish & Wildlife Service is the organization that manages the Washington Maritime National Wildlife Refuge Complex, which includes the local San Juan Islands National Wildlife Refuge. The SeaDoc Society is a program of the Wildlife Health Center, a center of excellence at the world-renowned UC Davis School of Veterinary Medicine. The Wildlife Health Center develops and administers innovative programs that create solutions for threatened wildlife and their ailing ecosystems.
