Arctic coasts constitute the critical interface between land and sea, and are subject to rapid changes caused by a warming climate. Current trends throughout the Arctic show increasing erosion trends, while other parts of the coast are experiencing prograding trends. Until now, a vast majority of our knowledge of Arctic coastal evolution is confine...

In 2020, the Hamlet of Kugluktuk initiated efforts to implement a coastal hazard assessment in response to ongoing erosion along the riverbanks of the old cemetery site situated in the delta of the Coppermine River. Additionally, addressing coastal processes along the entire coastline, particularly in the area of the breakwater, was of utmost impor...

Contrasting coastal environments are present along Canada’s northern coastline, making adaptation strategies highly site-speciEc. To better understand the response of Arctic and Subarctic coasts to increasing environmental pressure, shoreline changes in the 14 communities of Nunavik (northern Quebec, Canada) were investigated. Shoreline positions w...

Northwestern Nunavik (Quebec, Canada) is characterized by specific landforms and poorly documented examples of emerging coastal landscapes. In this study, we identified the different types of coasts and examined how they were morphologically reworked and shaped during the Holocene. This coastal region is currently emerging at rates of 8–9 mm/year d...

Emerging polar coasts have different geothermal regimes than those in submergence. While the scientific community is mainly concerned with rapidly eroding permafrost coastlines in sedimentary formations where relative sea level is rising, much less research has been dedicated to permafrost dynamics in emergent coastal regions where post-glacial upl...

Boulder barricades are poorly documented Holocene coastal landforms of Arctic and Subarctic regions. To understand the terrain factors and coastal processes explaining the occurrences of boulder barricades, we mapped and described these periglacial landforms along the emerging hypertidal coast of Ungava Bay, in Nunavik, northern Quebec, Canada. Thi...
