Abstract The arctic environment is changing: air temperatures, major river discharges and open water season length have increased, storm intensities tracks are changing. Thirteen quantitative studies of the rates coastline position change throughout Arctic show that recently observed environmental changes not led to ubiquitously or continuously increasing coastal erosion rates, which currently range between 0 2 m/yr when averaged for shelf seas. Current data probably insufficient, both...

Abstract The consequences of accelerating climatic warming on Arctic landscape evolution are far‐reaching. In Svalbard, glaciers rapidly retreating after the Little Ice Age, which leads to exposing new coastal landscapes from marine‐terminating glaciers. Precise quantification these changes was limited until complete dataset Svalbard glacier outlines 1930's made available. Here, we analyse change inventory data and demonstrate that retreat led a major shift towards land‐based in last...

Calving fronts is currently dominant form ice mass loss a major contributor to global sea‐level rise. An important yet under‐studied aspect this process transformation landscapes, where new lands coastal revealed due recession marine‐terminating masses. The evolution those freshly exposed paraglacial environments controlled by nearshore marine, terrestrial...

Abstract In Svalbard, the rapid glacier retreat observed since end of Little Ice Age (LIA) has transformed geomorphology and sediment budgets glacial forelands, river valleys, slope systems. To date, relatively little information exists regarding impact such a profound landscape degradation on evolution coastal environment. This paper addresses this deficiency by detailing post‐LIA fluxes to zone in Billefjorden, central Spitsbergen (Svalbard). We analysed response gravel‐dominated barrier...

ABSTRACT The calving of glaciers regularly produces tsunami‐like waves that pose a serious threat to coastal environments. Those strong are not only able move ice mélange and redistribute icebergs, growlers, or sea across fjord but also flood remodel neighbouring cliffs beaches. Here, we analyze over 90 years (1929–2023) zone changes occurred in front Eqip Sermia. We show play dominant role transforming the lateral moraine forming beach spit system south glacier front. Part former has...

The Arctic warms faster than any other region on Earth. As sea ice diminishes in response, wind speeds increase due to reduced drag over open waters. Lake sediments offer valuable records of these processes and their relation past climate change through the deposition wind-blown grains elements. This study reconstructs 8,000 years eolian activity using laminated from closed Dunsappietjørna Svalbard archipelago. site faces North Atlantic Westerlies as well Easterly winds. By...

The High Arctic, and Svalbard in particular, is currently experiencing rapid warming, which has serious consequences for various geosystem components, especially the cryosphere. Coastal areas are sensitive to these changes due their position at interface of marine terrestrial geosystems. Retreating glaciers, degrading permafrost, prolonged sea ice-free seasons, increasing weather extremes all key factors influencing development coastal areas. In this study, we focus on accumulation features...

The Arctic is warming nearly four times faster than the globe. drastic consequences of climate change are observed in high mountain areas located within coast. This where permafrost degradation and slope destabilization occur, which can be a direct cause large-scale landslides. Masses soil, rocks sediments reaching coast formation tsunami waves, which, other side fjord or strait, destroy infrastructure affect development coastal zone. An example this Vaigat Strait western Greenland, waves...

Since the end of Little Ice Age thousands kilometers new coastlines have been uncovered by retreating glaciers across Northern Hemisphere. This terrain begun to function as youngest coastal environments on Earth. As  retreat, they leave a mixture landforms including moraines, eskers, crevasse squeeze ridges, glaciofluvial deposits or glacially polished bedrock ready for the  transformation waves,  tides and currents. In extreme cases, newly exposed coastline takes...

Accelerated climate warming has caused the majority of marine-terminating glaciers in Northern Hemisphere to retreat significantly during 21st century. While glacier and changes mass balance are widely studied on a global scale, impacts deglaciation adjacent coastal geomorphology is often overlooked. We examined proglacial zones across period 2000-2020 provide complete GIS dataset new coastline released from glacial ice hemisphere that time as well lost due advance. identified total 2466...

Ongoing climate warming is leading to rapid changes in the Arctic environment, including major cryosphere. One of effects recent retreat marine-terminating glaciers exposure new coastlines. The calving such often produces tsunami-like waves that pose a serious threat coastal environments. These powerful are not only able shift glacial melange front ice cliffs and redistribute icebergs, but also flood rebuild local beaches. We present multidecadal analysis zone Eqip Sermia glacier (Greenland)...

Lagoon coasts are regarded as among the most vulnerable ecosystems to effects of climate change, serving conduits for interconnectivity between terrestrial, marine, and atmospheric systems. The stability lagoons is contingent upon several factors, including influence storm waves, ocean currents, sediment supply, sea level changes. To date, however, little research has been conducted on processes shaping evolution Arctic coastal lagoon systems (Smith et al., 2020). present study utilises a...

It has been widely reported that Arctic sea ice decreased in both extent and thickness, coupled with steadily rising mean annual temperatures. These trends have particularly severe along the rock coast of southern Svalbard. Concerns raised over potential for higher energy storms longer ice-free open water seasons to increase exposure coasts, consequently concentration infrastructure critical community survival, enhanced rates erosion. Here we present apply innovative remote sensing,...

Tidewater glaciers on the east coast of Svalbard were examined for surface elevation changes and retreat rate. An archival digital model (DEM) from 1970 (generated aerial images by Norwegian Polar Institute) in combination with recent ArcticDEM used to compare eleven glaciers. This approach was complemented a rate estimation based analysis Landsat Sentinel-2 images. In total, four 11 tidewater became land-based due their termini. The remaining retreated at an average annual 48 m year−1,...
