Dennis Staley, “Barry Arm Landslide in Prince William Sound: Background & Updates”

In May of 2020, scientists publicized a large slow-moving landslide in Barry Arm, a recently deglaciated fjord in Prince William Sound, Alaska. After rapid retreat of the glacial terminus, partial or catastrophic failure of the landslide has the potential to directly enter the fjord and generate a tsunami. Although the Barry Arm landslide is currently the most well-known landslide in this region, numerous other large, potentially tsunamigenic landslides exist in Prince William Sound.  To address these hazards, the U.S. Geological Survey (USGS) Landslide Hazards Program was authorized by Congress to conduct targeted research on landslides in Prince William Sound, Alaska, conduct hazard assessments, and coordinate with partner agencies to support the development of an early warning system. This presentation will describe ongoing efforts for advancing our understanding of landslide hazards for the purposes of reducing risk to the public, infrastructure, and critical natural and cultural resources.

Dennis Staley is a Research Physical Scientist in the U.S. Geological Survey Alaska Volcano Observatory in Anchorage, Alaska, where he leads a project related to landslide hazards in Prince William Sound.  This project is currently aimed at improving our understanding of large landslides and slope instabilities in recently deglaciated fiords.

Alysha Cypher, “Herring Patterns in Prince William Sound”

Dedicated herring research and monitoring in Prince William Sound has generated many insights into the natural history of this ecologically and economically valuable species.  It remains unclear, however, why Pacific herring have yet to recover from their 1993 collapse following the Exxon Valdez oil spill.  Since 2020, spawning observations, age class structure, and the occurrence of a strong year class indicate that there is reason to hope for this once lucrative fishery.  During this talk, you will learn about patterns indicative of Pacific herring populations and recent observations that leave both scientists and fishermen crossing their fingers for herring. 


Alysha Cypher is a postdoctoral researcher who has studied fish heart physiology, herring migration, and crude oil effects on young herring.  She grew up in western Pennsylvania, where she learned to be a naturalist while chasing frogs.  She has lived in Alaska for two short years and has developed a deep appreciation for the relationship between land, food, and Alaskan people.


Jackie Wilde, “Whittier Head of the Bay Development Plan”

Nick Docken, “Kittlitz’s Murrelet Space Use in Columbia Bay, Prince William Sound, Alaska"

The Kittlitz’s murrelet is a small seabird that nests in remote, alpine habitats, often associated with glaciers. They are found throughout Prince William Sound, but one area of particular interest is Columbia Bay where, due rapid glacial retreat, new shorelines are exposed providing ideal camping and hiking conditions for recreationalists. The potential for increased human disturbance in Kittlitz’s murrelet nesting habitat led to the need to better understand Kittlitz’s murrelet space use throughout the nesting season. During May of 2021, we marked 17 adult Kittlitz’s murrelets with satellite transmitters (Pinpoint Argos 75) in Columbia Bay. Our objectives were to: 1) identify nesting habitat characteristics, 2) determine feeding and roosting habitat, and 3) assess overlap of Kittlitz’s murrelet space use and human activity. Of 13 transmitters that collected substantial location data, 5 demonstrated nesting behavior. Apparent nest initiation dates ranged from 28 May to 19 June and nests were active for 10–24 days ( = 21d). Nest sites were in steep terrain at elevations of 800–1400m; nesting birds showed strong fidelity to foraging locations that were 11–30km from the nest. The 4 transmitters operational during late July showed a migration along the west coast of Alaska to the Seward Peninsula and the north slope. 


Nick Docken grew up in Wisconsin and went to UW Stevens Point, getting a wildlife degree.  Grad school at South Dakota State University deepened his passion to work with waterfowl and wetlands and ultimately led him to Alaska to work amongst all the amazing breeding grounds and avian diversity that our great state attracts from afar.  Nick has been the lead field technician with the wildlife crew on the Cordova Ranger District since 2015, working on the Copper River Delta and Prince William Sound.

***Jim Sumner, Lani Lockwood, Kathleen Keusenkothen, “Glaciers from the Interpreters' Perspective: What do you want, the facts or the story? Either way, we've gotcha covered!”

Three experienced rangers from the Glacier Ranger District will share experiences and tips on navigating the world of glaciers from tour boats in Prince William Sound. Their goal is to explain glaciers, help people understand what they are seeing, face climate realities and have a fabulous time along the way. Here’s how they do it.


Jim Sumner is an Alaskan that has been watching our glaciers change for over 50 years. The last 20 years he has been explaining the glaciers to the passengers on board the tour boats and ferries in Prince William Sound.  Jim has tried to help people better understand glaciers throughout the Chugach National Forest.


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.”

Dave Snider, “Tsunami Safety and Alerting Challenges for Prince William Sound”

The National Tsunami Warning Center’s mission is to provide timely, reliable, and accurate tsunami forecasts and warnings, and to promote community resilience. World history tells us that 80% percent of tsunami are generated by earthquakes.  This fact has defined the scope and capability of tsunami warning centers’ work for decades. Alaska history tells us that the risk of landslide-induced tsunami is all around us, and points to the need for new efforts to detect and warn for tsunami in Prince William Sound. Dave Snider will discuss the National Tsunami Warning Center’s mission and capability and talk about ongoing efforts with the USGS and partners to keep Prince William Sound communities aware and ready for local tsunami hazards.


Dave Snider works at National Tsunami Warning Center (NTWC) to ensure the science of detection and forecasting is clearly coordinated through NTWC’s official national alert and warning messaging. He ensures that this message is shared correctly through National Weather Service and Emergency Alert System connections. And he directs NTWC message to be as clear as possible so that partners and the public are enabled to respond immediately with the most appropriate action no matter when and where a message is received. Dave has performed 25 years of award-winning broadcast weather and social media work in Colorado, North Carolina, Missouri, and Alaska and is the NWS Alaska’s “Alaska Weather” TV Program Leader. Dave enjoys helping scientists become better communicators- so that complicated topics turn into usable information for all of us to make better decisions, inspire improved collaboration among scientists, and to encourage a sense of wonder about our world.

Barbara Lydon and Caio Poletti, “Tsunami Preparedness for Shore Camping and Kayaking”

This breakout session is a chance for guides, outfitters, and recreational paddlers to come together and talk about best practices around tsunami preparedness when shore camping and kayaking. NOLS has developed written practices for our expedition with the help of Bret Higman. Topics will include: Preparing for a possible tsunami on all your trips. How best to communicate out of cell service and get information about tsunami/earthquake danger. Responding to a tsunami if onshore or on the water close to shore. Many companies and guides have developed similar plans, and this will be a time to share what is practical and what paddling in Prince William Sound has been like with the pronounced risk of landslides in the past few years.


Barbara Lydon has been with the US Forest Service for nearly two decades, working in the field of federal Wilderness and Wilderness Study Area management. She began her career in Juneau on the Tongass National Forest, and has also spent many years as an outdoor guide. Barbara moved to the Chugach National Forest in 2011 to work in the Wilderness program on the Glacier Ranger District. She was previously a public school teacher, and when she’s not in the field, she also works an artist and coordinates the Voices of the Wilderness Artist Residency Program for the NPS, USF&WS and USFS in Alaska.  She is a founding member of the Prince William Sound Stewardship Foundation and with her husband, Tim, enjoys every chance she gets to show their young daughter the wonders of the Sound.


Caio Poletti is a Program Supervisor and Curriculum Project Manager at NOLS. He comes from Brazil and has been living in Alaska for the past few years. He is passionate about education and all sea-related topics. As a sea kayaker, he has 12 years of instructing experience around the world.

***Skye Steritz, “Kelp Farming in Prince William Sound”

Mariculture has the potential to be a positive force for this region, if done thoughtfully and responsibly. Kelp farming is becoming more popular across Alaska. In fall 2021, the first few small-scale commercial kelp farms in Prince William Sound seeded their lines for the first time. Among them was Noble Ocean Farms, owned and operated by a young, local couple: Skye Steritz and Sean Den Adel. Noble Ocean Farms’ mission is to enhance food security and resilience for coastal Alaskan communities. 

In this presentation, Skye will walk us through her journey of becoming an ocean farmer at age 28. She will describe what kelp farming entails, why it is regenerative for both the sea and our bodies, and some of the challenges beginner farmers in this nascent industry are facing. Skye will also touch on the ways of cooking with kelp and some of the nutritional benefits of eating sea vegetables, such as kelp. 


Skye Steritz is a Celtic descendant working on Eyak land (Cordova, Alaska). She is a regenerative kelp farmer, environmental educator, and elementary school Special Education Aide. Steritz’ top passions are social and environmental justice. Steritz is a volunteer for Prince William Sound Regional Citizen Advisory Council and sits on the Advisory Circle of the international RIVER Collective. She studied International Water Cooperation and Diplomacy in graduate school, focusing on ways countries collaborate to manage transboundary waterways.

Andrew Abyo, “Indigenous Kayaks of Alaska”

Andrew Abyo will discuss different Indigenous kayaks of Alaska and how culture and environment influenced their design. Besides kayak design, topics will include materials used,  hunting implements, and clothing. 


Andrew Abyo is an Alutiiq carver and kayak builder who was raised in the Bristol Bay village of Pilot Point. Andrew's goal is to learn and pass on cultural traditions by showing and teaching different things than you normally don't get to see except in museums.  Andrew's work is recognized as museum quality and he has taught for Alaska Pacific University, the Alaska Native Heritage Center, and many other organizations.
