Abstract The rapid formation of glacial lakes is one the most conspicuous landscape changes caused by atmospheric warming in glacierised regions. However, relatively little known about history and current state High Arctic. This study aims to address this issue providing first inventory Svalbard, focusing particular on post-Little Ice Age evolution their typology. To do so, we used aerial photographs satellite imagery together with archival topographic data from 1936 2020. comprises...

Glacier-fed hydrological systems in high latitude regions experience seasonal variation meltwater runoff. The peak runoff usually coincides with the highest air temperatures which drive production. This process is often accompanied by release of sediments from within glacier system that are transported and suspended concentrations as they reach proglacial realm. Sediment-laden later to marine environment expressed on surface fjords coastal waters sediment plumes. Direct monitoring these...

Contamination of water and sediments with arsenic heavy metals is a global issue affecting human health. Regions covered Quaternary deposits have received little attention from the point view flux to surface water. This study aims determine other waters in an area affected by former Złoty Stok gold mine. was caused arsenic, whereas concentrations were usually within quality standards. Arsenic contamination increased lower part basin sediments, exceeded standards 2 orders magnitude. mass 8...

Small Arctic coastal catchments and lagoon systems are some of the most vulnerable to climate change. Glacial retreat development glacial lakes drainage provide opportunities for hazardous events such as GLOFs. We observe that stability lagoons their associated barriers controlled by frequency magnitude storms approaching coasts, access sediment supplies resilience sea-level rise. Based on multidecadal remote sensing data, we were able identify rate recession, lakes, vegetation response...

The direct consequence of the ongoing climate-forced glacier recession is expansion forelands. A common characteristic these proglacial changes emergence glacial lake systems that act as reservoirs meltwater and sediment, thus forming new landform components in paraglacial landscapes. This study examines geomorphological development a distinct system zone Crammerbreane Svalbard since end Little Ice Age (LIA). Our findings demonstrate initial lakes formed foreland at start 20th century...

Abstract The structural change of the Svalbard landscape from glacially dominated to paraglacial, that has taken place since termination Little Ice Age (ca. 1900) is expressed by widespread retreat glaciers and progressive exposure glacial landforms. This study provides insights into rate post‐LIA deglaciation associated paraglacial transformation in foreland Gåsbreen, one first ever investigated glacier systems Arctic. Glacier situated Sørkapp Land (Southern Spitsbergen), a region...

Abstract. Rapid changes of glacial lakes are among the most visible indicators global warming in glacierized areas around world. The general trend is that area and number increase significantly high mountain polar latitudes. However, there a lack knowledge about current state High Arctic. This study aims to address this issue by providing first lake inventory from Svalbard, with focus on genesis evolution since end Little Ice Age. We use aerial photographs topographic data 1936 2012...

The study investigates glacial lakes in Svalbard, examining examples from the forelands of Gåsbreen, Crammerbreen, Knivseggbreen, Neppebreen and Ragnarbreen, each representing different classifications lakes, including ice-dammed, frontal moraine-dammed medial moraine-dammed. These serve as key indicators ongoing climate change effects deglaciation processes polar landscapes. Quantitative analyses reveal notable differences among selected lakes. For instance, Goësvatnet experienced cyclical...

Kotlina Jeleniogórska położona jest u podnóża Karkonoszy, gdzie swoje źródła mają liczne rzeki i potoki zasilane opadami deszczu śniegu. Położenie to niesie więc ze sobą zagrożenia strony cyklicznych powodzi, a współcześnie coraz częściej okresów suchych. Pierwsi osadnicy pojawili się tutaj jeszcze we wczesnym średniowieczu wykorzystując powszechny dostęp do wód powierzchniowych, zaczęli znacząco ingerować w jej przebieg oraz retencję. Rekonstrukcja powierzchniowych ujęciu ilościowym oparciu...

The change in the structure of polar landscape since termination Little Ice Age (ca. 1900) is expressed by widespread retreat glaciers, progressive exposure glacial landforms at ice margins and opening marginal zones to increasing paraglacial periglacial processes operating synchronously adjacent areas. This study provides insights into rate post-LIA deglaciation associated transformation foreland Gåsbreen, a glacier situated north-western Sørkapp Land, region characterized one fastest rates...

<p>The retreat of glaciers in response to climate warming leads substantial changes not only their mass balance, size and runoff but it also impacts proglacial zones. A common characteristic these is the development glacial lake systems, which serve as meltwater sediment reservoirs become new elements Arctic paraglacial landscapes. This paper investigates evolution a unique system that has developed zone glacier Cramerbraene Svalbard since termination Little Ice...
