Running with a Tough Crowd: Cuvier's Beaked Whales and Fin Whales in Offshore Naval Training Areas ... Abstract

The Southern California Bight is home to one of the largest military training range complexes in the world (“SOCAL”), including nine instrumented areas and thirteen designated operations area throughout its coastal, near shore, and offshore reaches. This region, which extends from Point Conception south to Northern Baja California and up to 100nm off the mainland coast, also encompasses a variety of marine habitats, including offshore banks, islands, and deep basins which in turn support a broad diversity of marine mammal species, several of which are endangered or considered sensitive to anthropogenic impacts. The Southern California Offshore Range (SCORE), centered on San Clemente Island, is a focal point within SOCAL. It includes an array of nearly 150 bottom-mounted hydrophones called SOAR which is often used for anti-submarine warfare training involving 53c mid-frequency active sonar- the type that has been associated with mass strandings of beaked whales in other parts of the world.

We began conducting collaborative surveys at SOAR in 2006. We joined forces with other scientists from the Naval Undersea Warfare Center, Naval Postgraduate School, and Scripps Institution of Oceanography to address a significant lack of data concerning the distribution, habitat use, and behavior of cetaceans in the region. We knew that fin whales occasionally formed dense aggregations in this remote area, but were very surprised to discover a much higher density of Cuvier's beaked whales than had previously been described anywhere along the US West Coast. Thus the project began to focus specifically on these two species, both of which have presented significant research challenges historically and have specific sensitivities to many of the activities that occur regularly on the range (ship strikes in the case of fin whales, sonar in the case of beaked whales).

This presentation will summarize our work to date in Southern California as we attempt to unravel the mysteries of these two enigmatic species. We will summarize what we have learned through visual surveys, photo-identification, and satellite telemetry, and how we hope this new information can be used to make better informed management decisions for these populations and others that exist in areas of frequent military activity.

Erin Falcone and Greg Schorr lead Cascadia's marine mammal studies at SCORE. They began working with Cascadia in 2003 and 2004, respectively, and throughout that time have worked on a variety of cetacean studies at points from the Aleutian Islands to Australia, and with everything from porpoises to blue whales. Much of their field work in the coming year will be small vessel based surveys along the coasts of California and Washington.

The bowhead whale in the age of oil: a brief review of research past and present ... Abstract

The Bering-Chukchi-Beaufort population of bowhead whales (Balaena mysticetus) was heavily exploited by commercial whaling in the mid‑ to late 19th Century. It is listed as endangered under the US Endangered Species Act and as a species ‘of special concern’ in Canada (COSEWIC 2005). Since the late 1970s this recovering population has been contending with anthropogenic activities related to oil and gas exploration.

The first studies to investigate the impacts of these industry activities on bowhead whales were initiated in the early 1980s. These studies consisted of dedicated behavioural response studies and distribution surveys. Results suggested that bowhead whales exposed to industry activities exhibited responses ranging from localized displacement and subtle changes to their surface-respiration-dive (SRD) behaviors to wider avoidance of industry activities. The SRD behavior of cetaceans provides a means to quantify changes in behavior and have been used as a method to characterize activity states. Quantitative assessments of SRD patterns are also an important method of assessing the affects of industrial activities.

My research involves the analysis of over 20 years of bowhead behavior data, collected with and without the presence of industry activities and I am using these data to explore the potential effects of oil and gas exploration on bowhead whale behaviour. In this talk I will introduce the key issues surrounding the bowhead whale and industry in the western Arctic; I will go on to briefly summarize the past research and will share my preliminary results and what their implications may be.

Frances Robertson is a PhD candidate in the Marine Mammal Research Unit at the University of British Columbia. She has been involved in a variety of cetacean research projects here in the Pacific Northwest and in Scotland. Most of Frances’ work has centered on the impacts of human activities on cetaceans. Since 2006 Frances has specialized in carrying out assessments and monitoring of oil and gas industry activities on marine mammals. This work has involved vessel-based and aerial-based surveys for marine mammals, mainly associated with monitoring and mitigation of the effects of seismic surveys on marine mammals and (where they occur) sea turtles. Frances’ experiences with industry have widened her research interests and have led her to focus her efforts on investigating the impacts of seismic survey activity on bowhead behaviour and distribution in the Alaskan Arctic. Frances is also a committee member for the recently launched Marine Mammal Observers Association and is the Student Representative for the NW Student Chapter of the Society of Marine Mammalogy.

Investigating the usability of DNA from sloughed skin for individual identification and kinship analysis in humpback whales (Megaptera novaeangliae) ... Abstract

Obtaining genetic samples from cetaceans can be logistically challenging. Various methods of DNA collection for cetaceans have been utilized in the past including biopsy darting (invasive, strict permit regulations), fecal sampling (difficult to locate, reduced quality DNA) and sloughed skin collection. In this study, we demonstrate that sloughed skin collection provides a non-invasive, low-cost means of acquiring high quality DNA for individual identification of humpback whales (Megaptera novaeangliae). Using a small subset of a large (> 1,500 samples) long-term sloughed skin dataset, we compared genotypes from multiple samples of 11 known individuals (confirmed from field observations and photo-ID) that had been seen within and/or across field seasons. For all cases in which we obtained more than one skin sample from a whale identified in the field as the same individual, we confirmed that the genotypes were identical. We used a panel of 14 microsatellite markers and M13 universal primer labels to compare genotypes of samples collected from five mothers and their calves and demonstrated that, in all confirmable cases, known mothers shared one-half of their genotype with their observed calves. In addition, 129 males and calves were run using COLONY to investigate kinship and full/half sibling relationships. M13 universal primer labels enabled us to determine genotypes at a fraction of the price required of fluorescent-labeled dye primers. Careful analysis of genotypic data from sloughed skin allows us to address questions about humpback whale social dynamics, reproductive success, ecology and life history. In the future, these techniques can be applied to the larger humpback whale dataset and to other cetacean species where sloughed skin can be collected.

Sophie Pierszalowski graduated from the University of Washington in the spring of 2010 with a B.S. in both Aquatic and Fisheries Science and General Biology. After completing her senior thesis in collaboration with NOAA's National Marine Mammal Laboratory, she was hired to expand on the project; investigating the usability of humpback whale sloughed skin for genetic analyses. She hopes that this study will encourage the use of noninvasive data collection by demonstrating the value of this method. Sophie recently received an ACS/PS student grant to present her findings at the 11th International ACS conference this past November. Prior to her employment at NMML, Sophie worked as a student intern at the NWFSC conducting a collaborative research project involving the role of activity states and gender on swimming and diving parameters of Southern Resident killer whales. Both positions have inspired her to continue cetacean-related studies and she plans on applying to a Master's program next fall.

Killer whale diseases ... Abstract

Wildlife diseases can devastate populations and impact human health. Some pathogens have decimated cetacean populations around the world and have the potential to impact the endangered Southern Resident Killer Whale population. Identifying and preventing these diseases, however, can be tricky as very little is known about diseases of killer whales. Joe Gaydos will take you on a decade-long journey to learn more about the diseases of these top predators and how what they are findings could prevent killer whale recovery.
