Journey for Aspiring Students Pursuing Ecological Research (JASPER) immerses students into a real marine science project, fostering development of research skills, confidence, communication skills, and future careers.
The Marine Mammal Institute showcases its work this month as part of HMSC Marine Science Day on April 9. Each of our labs has a featured page in the virtual Exhibit Hall, including the Oregon Marine Mammal Stranding Network.
In this 7-minute video, Stranding Program Manager Jim Rice describes what services the Oregon Marine Mammal Network provides and how it responds to marine mammal strandings in Oregon. This work keeps us vigilant about changes in the health and challenges to the welfare of marine mammals along the Oregon coast, providing a unique window into the state of the natural world.
To report an injured, stranded, or dead marine mammal in Oregon, call 800-452-7888 (Oregon State Police Tip Line), 541-270-6830 (Stranding Network Hotline), or email firstname.lastname@example.org. Marine mammals are protected by federal law. For their safety and yours, it is illegal for unauthorized persons to disturb, handle, or feed them.
Pitman told National Geographic, “This is the biggest predation event on this planet: the biggest apex predator taking down the biggest prey. We don’t have dinosaurs anymore, so for me as a whale biologist and a zoologist, it’s an amazing thing.”

In this recorded presentation, Director Lisa T. Ballance presents the fascinating story of the origin and evolution of cetaceans, as evidenced by the fossil record and artistic impressions of cetacean ancestors.
MMI Associate Director, Scott Baker, initiated an archive of genetic samples from whales and dolphins of New Zealand when he was professor at the University of Auckland. Now, under the curation of his former students, Associate Professor Rochelle Constantine and Dr. Emma Carroll, this archive continues to provide new information on the evolution of whales. Most recently, DNA samples from this archive were used to help describe a new species of beaked whales named in honor of a renown Māori naturalist, Ramari Stewart, who collected a stranded specimen of the new species.
Scott and his Senior Faculty Research Assistant, Debbie Steel, contributed to the formal description of "Ramari’s whale" published this October in the Proceedings of the Royal Society B.Figure: Sampling locations in the NA (black circles) and SH (yellow circle).

Do gray whales head to Baja California for the winter for the same reason we do? A vacation from the cold? Apparently not. A paper by MMI Affiliate Jim Sumich that analyzes heat loss in gray whale calves shows, surprisingly, no substantial benefit to being born in warmer waters. The real motivation behind the southward migration might actually be avoiding those pesky killer whales.

“If I were to describe the Pacific Storm in one word, it would definitely be ‘resilient’,” said Lisa Ballance, director of OSU’s Marine Mammal Institute. “She was built as a commercial fishing vessel and later gifted to MMI. Now her future is with marine mammal research and broader research pertaining to marine ecosystems.” Read the vessel's story in "Journey of the Pacific Storm: From commercial fishing to marine research."
MMI Director Lisa Ballance is leading a team of 12 scientists and crew on a month-long research expedition aboard the R/V Pacific Storm to search for whales that have never before been identified alive in the wild. The Beaked Whale Expedition to the Eastern Pacific Gyre ("GyreX") draws on the expertise of both OSU and NOAA to locate, identify, and ultimately help protect these cryptic whales. Follow along the journey at our blog.
MMI Affiliate Faculty Rachael Orben coauthored a recently published paper that examines the use of marine management areas around the Falkland Islands. The Falkland Islands are home to globally significant populations of marine predators, including 75% of the global population of Black-browed albatross, 50% of the global population of South American fur seals, and 30% of the global population of Rockhopper and Gentoo penguins. The proposed marine management areas are an important step towards an ecosystem approach to conservation in the region.
Early each year, gray whales can be found in the protected, shallow waters of San Ignacio Lagoon. The Marine Mammal Institute has been hosting educational expeditions to the lagoon and surrounding areas for more than 30 years. Travel with us, for a truly remarkable marine mammal experience.
We use electronic tags to remotely "ride along" with whales as they go about their lives. Developing a better understanding of the patterns of whale habitat use, the reasons behind it, and whales' responses to different conditions, leads to improved conservation measures for the whales and the marine environment in which they live.
Marine mammal stranding networks provide a first line of detection for marine animal and ocean health concerns. The Oregon Marine Mammal Stranding Network (OMMSN) is based here at the OSU Marine Mammal Institute, managed by Jim Rice. It is a collaborative organization comprising Oregon universities, state and federal agencies, and citizen volunteers that offers continuous surveillance for diseases and causes of death in marine mammals, particularly in areas frequented by the general public.
For an overview of the OMMSN, we invite you to watch the 8-min video shown here. The objectives of the network keep us vigilant about changes in the health and challenges to the welfare of marine mammals along the Oregon coast, providing a unique window into the state of the natural world.
Whales are big, dynamic, and spend most of their lives under water — factors that challenge our ability to study their ecology, health, and behavior. Drones, or Unoccupied Aerial Systems (UAS), are helping us overcome some of these challenges by offering a new, and noninvasive, perspective on the lives and world of whales. Over the last six years, the GEMM Lab has developed new methods, applications, and knowledge based on the use drones to study marine mammals, including documenting new whale foraging behaviors, understanding how krill respond to whale predation, and the relationship between whale body condition and environmental conditions. For more information, check out the Drone-based Innovative Assessments of Megafauna Offer New Discoveries (DIAMOND) project.
In early February, Debbie Steel and Scott Baker of the Cetacean Conservation and Genomics Laboratory hosted the biennial meeting of the South Pacific Whale Research Consortium (SPWRC). This year’s meeting was limited to members of the SPWRC Executive Committee and held virtually due to the COVID-19 pandemic. Despite these limitations, the meeting was a success, with attendees sharing updates on research and conservation initiatives currently underway across the South Pacific region.
"I write this as my first-year anniversary with the Marine Mammal Institute approaches. Despite these unprecedented times, it has been a fabulous year for me and for the Institute. And it has been an historic one."
Photo-identification is not just for whales! MMI researchers and interns use photo-id to evaluate habitat use of harbor seals along the central Oregon coast. Harbor seals haul out on rocks during low tide to rest. This creates the perfect opportunity to collect photographs of the seals and their unique spot patterns. Collecting these photographs at several haul-out sites along the coast, researchers can compare photographs from each region to gain a better understanding of the habitat use of the seals. Aimee Aguilar, an undergraduate intern with MMI, spent most of her summer taking photographs and cataloging individual seals at the haul-out site in Alsea Bay.
Photo-identification is an important tool that helps MMI researchers keep track of the whales we see. Happywhale is an online photo-ID resource that uses artificial intelligence and machine learning to automatically compare and match photographs of individual humpback whales. The software can match whales 40 times faster and more accurately than the human eye! Explore the WHET Lab page at Happywhale to take a closer look at the humpbacks we have identified, from Antarctica to the Bering Sea. Photo-ID catalogs such as this one help scientists around the world collaborate to understand whale movements and identify critical habitats.
The Cetacean Conservation and Genomic Laboratory is working to develop methods for detection and identification of whales and dolphins using environmental DNA, or (e)DNA. This is the DNA that organisms shed as they move through the environment. In a recently completed project, we took advantage of a fixed acoustic array maintained on the Navy’s Atlantic Undersea Test and Evaluation Centre (AUTEC) in the Bahamas. With this acoustic assistance, we were about to locate and collect eDNA samples from Blainville’s beaked whales (pictured to the right), revealing previously unreported diversity in mtDNA haplotypes from this enigmatic species.
The GEMM Lab is wrapping up their sixth consecutive year of data collection on gray whale ecology and physiology off the Oregon coast, including observations of the well-known whale “Scarlett” and her new calf, seen here riding on the back of her mom. More information about this research project can be found in the GEMM Lab blog and the research project webpage.
