We welcome Letters of Commitment from anyone interested in contributing to the Arctic T-SLIP conversations in 2024-2025, as we are submitting a Planning Proposal to NSF due July 17, 2023.


Landslides are a massive disturbance in terrestrial ecosystems—but along coastlines, the movement of tons of rock and soil into the water can generate tsunamis, posing life-threatening risks to nearby communities. Unfortunately, thawing permafrost and glacial melt have increased the potential for these types of dangerous events.

Arctic T-SLIP aims to bring together experts from academia, government agencies, and local communities to increase our understanding and preparedness of landslide-generated tsunamis in regions affected by thawing permafrost and/or melting glaciers.

The partnership evolved from a group of scientists discovering the large unstable slope in Barry Arm, Prince William Sound, Alaska in the spring of 2020. The discovery spurred the federal government to fund investigations into the hazard by increasing the USGS’ national landslide program funds. The State of Alaska also established a monitoring program and a website to inform and update the public.

In 2023, the Arctic T-SLIP is preparing a Planning Proposal to the National Science Foundation Office of Polar Programs “Large Project Support” to fund workshops and conferences aimed at developing several focused science projects. This includes collaborators in the US, Norway, Greenland, and Canada, for example.

Arctic T-SLIP welcomes new collaborators, please submit your interest here.
