Indigenous Knowledge and observations improve Arctic Ocean model skill and relevance

Ocean models are increasingly central to understanding and anticipating change in ocean ecosystems. Yet these tools have been developed almost entirely without the people who observe, depend on, and steward these environments. Here we describe a framework for building Arctic Ocea...

The plausible relationship between deep long-period earthquakes and volatiles: a case study of the Alaska-Aleutian arc

Abstract Deep long-period (DLP) earthquakes are observed beneath volcanoes in various tectonic settings during background activity, unrest, and eruption. The exact processes generating DLPs have been subject to ongoing debate, as they may provide insight into deep magmatic plumbi...

Satellite observations, plume dynamics, and volcanic lightning from the 2023 eruption of Shishaldin Volcano, Alaska

Abstract The 2023 eruption of Shishaldin Volcano, Alaska, provided an unusually well-monitored example of a “dry” (non-hydromagmatic) explosive basaltic eruption with sustained, buoyant plumes, and pyroclastic density currents. Here, we examine the 13 basaltic paroxysms that occu...
