Eroding permafrost coasts are likely indicators and integrators of changes in the Arctic System as they susceptible to combined effects declining sea ice extent, increases open water duration, more frequent impactful storms, sea-level rise, warming permafrost.However, few observation sites have yet link decadal-scale erosion rates with changing environmental conditions due temporal data gaps.This study fidelity coastal bluff observations using near-annual high spatial resolution (<1 m)...
Arctic sea-ice is declining in extent, leaving coastlines exposed to more storm-wave events. There an urgent need understand how these changes affect geomorphic processes along coasts. Here we describe spatial and temporal patterns of shoreline two geomorphologically distinct, dominated reaches the Chukchi Sea coastline over last 64 years. One study area encompasses west- southwest-facing, coarse-clastic ice-rich bluffs Cape Krusenstern (CAKR). The other covers north-facing, sandy shorelines...
Globally, coastal communities experience flood hazards that are projected to worsen from climate change and sea level rise. The 100-year floodplain or record commonly used identify risk areas for planning purposes. Remote often lack measured elevations require innovative approaches estimate elevations. This study employs observation-based methods the elevation in Alaska compares results models, infrastructure locations, rise projections. In 46 analyzed communities, 22% of structures located...
Arctic amplification of climate change has resulted in increased coastal hazards impacts to remote rural communities Alaska where conducting research can be difficult, requiring alternate methods for measuring change. The pilot program, Stakes Stakeholders, was initially planned funded from 2016–2018. Upon project completion the work shifted individual community’s partnering with several agencies continue work. Stakeholders three years and upon entities This showcases a successful long-term...

Charlotte (North Carolina), ISSN 0749-0208. is one the foremost hazards that circumpolar communities face. Climate change warming temperatures are anticipated accelerate coastal change, increasing risk communities. Most hazard studies...
During the winter of 2016, anomalous sea ice conditions and a powerful storm culminated in destructive erosion event along Chukchi Sea coastline Cape Espenberg, Alaska. This is commonly referred to as an "ice push" or "ivu," Inupiat word for ridging event. In this paper we report process impact by combining traditional ecological knowledge, news accounts, meteorological data, remote sensing, ground surveys. The mid-winter detachment shorefast was caused low-pressure system wind-driven swell...
Abstract Infrasound (low frequency sound waves) can be used to monitor and characterize volcanic eruptions. However, infrasound sensors are usually placed on the ground, thus providing a limited sampling of acoustic radiation pattern that bias source size estimates. We present observations explosive eruptions from novel uncrewed aircraft system (UAS)‐based sensor platform was strategically hovered near active vents Stromboli volcano, Italy. captured eruption short‐duration explosions jetting...

Coastal hazards are of increasing concern to many Alaska’s rural communities, yet quantitative assessments remain absent over much the coast. To demonstrate how fill this critical information gap, an erosion and flood analysis was conducted for Goodnews Bay using assortment datasets that commonly available Alaska coastal communities. Measurements made from orthorectified aerial imagery 1957 2016 show shoreline eroded 0 15.6 m at a rate posed no immediate risk current infrastructure. Storm...
