Jane Belovarac, Halley Werner, and Savannah Costner, “Northern Sea Otters and the Alaska SeaLife Center: 25 Years of Care”

The concept for the Alaska SeaLife Center (ASLC) began in the aftermath of the Exxon Valdez Oil Spill, where there was a need for a facility that could support scientific research and marine animal rehabilitation.  Since its opening in 1998, the ASLC remains to be the only marine mammal rehabilitation facility in Alaska. Over the last 25 years, the ASLC has received thousands of calls from the public reporting distressed marine mammals and birds throughout the state, resulting in the rehabilitation and release of over 600 individual animals. Of these responses, over 50 stranded sea otter pups have been raised to become ambassadors for this species, living in aquariums and zoos around the world. In 2012, the ASLC initiated the Oil Spill Wildlife Response Team where animal care staff work with oil spill response organizations to prepare for a potential event. Mobile response units can respond to an incident when called into service.  Meet the ASLC's Wildlife Response team, and learn about their role in sea otter rehabilitation and oil spill preparedness.


Jane Belovarac, Wildlife Response Curator; Halley Werner and Savannah Costner, Animal Care Specialists.

Jane, Halley, and Savannah have over 40 years of combined experience caring for marine mammals. Over the years, they have had the honor to work closely with a wide variety of Alaskan marine animals - ranging from ducklings to beluga whales, and of course northern sea otters. As members of the Oiled Wildlife Response Team at the ASLC, they help train colleagues and volunteers about caring for these animals in the event of a catastrophic spill.

Dennis Staley, “Progress in Understanding Landslide Hazards in Prince William Sound, Alaska”

Should it fail catastrophically, the Barry Arm landslide, located in northwestern Prince William Sound, Alaska, represents a significant hazard to nearby communities, infrastructure, commercial and recreational interests, and important natural and cultural resources. In July of 2021, an interagency team of interdisciplinary scientists began a focused effort to better understand not only the Barry Arm landslide, but also other potentially hazardous landslides in Prince William Sound. The purpose of this presentation is to highlight the broad scope of these efforts and provide brief updates on the progress of different components of this interagency collaboration. This presentation will highlight updates on the progress on characterizing regional controls on landslide size and distribution in Prince William Sound, the monitoring efforts at the Barry Arm landslide and how these are used to inform operations at the National Tsunami Warning Center, and plans for future work.

Dennis Staley is a Research Scientist in the U.S. Geological Survey Alaska Volcano Observatory in Anchorage, Alaska, where he is the USGS lead of a multi-agency effort that aims to improve our understanding of landslide hazards in Prince William Sound, Alaska.

Scott Langley, “Meaningful Measurements for Rapid Tsunami Detection”

Timely and accurate measurement of an impactful tsunami wave leads to effective alerting for at-risk communities.  The U.S. National Tsunami Warning Center (NTWC) has installed critical water-level gauges that provide necessary reporting of discrete changes from remote and wild Alaska. This observation method is challenged by the remote environment, communication and power challenges, and ability to physically reach each station for upgrades and repairs.  This design, while used in other parts of the Alaskan outer coast, is experimental for landslide tsunami monitoring- but may be a critical tool in future work within Prince William Sound.

Scott Langley is an IT Specialist & Senior Electronics Technician at the National Tsunami Warning Center. He has an extensive background in telecommunications, satellite communications, electronic systems integration, sea level monitoring and seismic station installations.

Maryann Fidel, “AK DEC Marine Water Quality Monitoring and EVOS Lingering Oil”

Some of DEC’s work in PWS includes water quality monitoring and assessment of EVOS lingering oil.


To understand the impact of cruise ships on local water quality, DEC has been monitoring ambient conditions in and around Alaska’s high traffic ports and shipping lanes since 2015. This information can be used to identify locations of concern where additional sampling is needed and to inform discharge permits. During the COVID pandemic large cruise ships were absent from Alaskan waters. This provided the perfect situation to measure water quality minus this potential impact. Results demonstrate little differences among 2022 with cruise ships present and 2020-21 when cruise ships were absent. Locations have been identified with concerning levels of fecal coliform and enterococci, but levels were not elevated by the presence of cruise ships. Additional work is planned in Whittier to collect baseline water quality data before the new cruise ship dock becomes operational.


Information is also provided about DEC’s assessment of EVOS lingering oil. This is a public process, so input is welcome.

Maryann Fidel manages water quality monitoring in ports and shipping lanes for the State of Alaska, Department of Environmental Conservation. Before that, she provided science support for Alaska Native nonprofits on a variety of different research topics, often with a focus on water quality. She has a BIG love for Prince William Sound that began while growing up in Anchorage and grew while guiding kayak trips out of Valdez, working on her thesis at APU, and as a Wilderness Kayak Ranger for the Glacier Ranger District.

Harmony Wayner, “Alaska’s Marine Debris Action Plan”

Marine debris is a complicated issue worldwide and uniquely challenging and impactful in Alaska. Work is beginning on a Marine Debris Action Plan for Alaska. This is a collaborative process to identify and capture the existing actions, identified needs, and proposed priorities within the marine debris issues in Alaska. In this listening session, participants can share their perspectives and knowledge on the marine debris issues they observe, current actions underway, and proposed solutions moving forward.

Harmony Wayner is a Tribal member of Naknek Native Village and a 5th generation commercial fisherwoman. She has a B.S. in Biology from the University of Alaska Southeast and a Masters in natural resource management from the University Centre of the Westfjords, Iceland.

Scott Pegau, “Status of PWS Herring”

The Exxon Valdez Oil Spill Trustee Council has been supporting research and monitoring of herring in Prince William Sound. This presentation will cover the latest observations on the herring population and some of the research highlights. The results of the 2023 spawn surveys, preliminary views on the age of the spawning population will be provided along with what they may mean to the 2023 population estimate. Ways to follow our efforts will be provided.

“Volunteer Monitoring of Intertidal Habitats”

Understanding the recovery of habitats from oil spills is difficult because the recovery must be considered in the context of natural variability. After the Exxon Valdez oil spill, Dr. Alan Mearns of NOAA began photographing features in Prince William Sound as a tool for monitoring the recovery of the intertidal habitat. The photographs now have value in understanding the ecology of the intertidal zone. We are seeking assistance in collecting pictures of these features so we can follow how our environment is changing through time.


Scott Pegau is the Research Program Manager for the Oil Spill Recovery Institute and has been coordinating the Herring Research and Monitoring program in Prince William Sound since 2009. Understanding the recovery of the intertidal habitat and herring populations from the Exxon Valdez oil spill are important components of his work. He received his Ph.D. in physical oceanography from Oregon State University where he specialized in remote sensing and in-water optics.

Carolyn Spencer, Lani Lockwood, and Kathleen Keusenkothen, "What is a Glacier?"

Carolyn Spencer comes to the interpretive world with a background in outdoor education from Colorado. Her vibrant perspective generates curiosity among participants as she most often engages audiences through activities and hands-on teaching.

Lani Lockwood grew up in Connecticut, a once glaciated landscape she didn’t truly appreciate till coming to Alaska. 46 years living just a few miles from Harding Icefield, 9 seasons with Kenai Fjords NP, and 5 on the Forest help her give visitors a greater understanding and appreciation of all things glacier.


Kathleen Keusenkothen has been learning about and explaining  glaciers every day for 18 seasons on Portage Lake, PWS tour boats, the ferry and the train to Spencer/Grandview.  She loves sharing stories with the public and is  guided  by  the educational concept, “better to be the guide on the side, than the sage on the stage.”

Boat Tour, May 15th
For the first time, this year's Symposium included an extra half day of opportunities.

Participants journeyed up to Blackstone Bay with Lazy Otter Charters, going close to shore and admiring the sheer cliff walls and tumbling waterfalls in route to two tidewater glaciers, Beloit and Blackstone. They learned from interpreters while sitting at the face of a wall of ice. They learned about bird ecology as they cruised up to a rookery where thousands of birds nest and raise their young. They experienced the natural geology of this glacier-carved fjord and learned about the common plants found in this area. The captain assisted in a plankton tow while underway, and participants got a chance to look in microscopes at the plankton, which is the start of the food chain supporting our rich marine life. Participants left this tour with foundational knowledge and experience to share and build upon this summer.
