Glacier surge as a trigger for the fastest delta growth in the Arctic ...
2024年11月14日 · The glacier advanced ca 1200 m since 2018 and suddenly stopped in June 2020 followed by the rapid formation of a delta system in front of its subglacial meltwater outlet.
Ocean warming drives immediate mass loss from calving glaciers …
2 天之前 · Ocean-driven glacier mass loss in changing high Arctic regions. The northern Barents Sea has experienced exceptional rates of atmospheric warming 2 and rapid sea ice loss 3 during recent decades, ...
Space for Shore: Sentinel-1 reveals Arctic glacier retreat
2024年11月19日 · Sentinel-1, part of the European Union’s Copernicus program, uses synthetic aperture radar (SAR) technology to capture high-resolution data under challenging Arctic conditions, ensuring consistent, year-round monitoring of these critical glaciers. A key finding from the analysis is the yearly extent of glacier fronts.
Satellite images reveal hidden retreat of Arctic glaciers
2024年11月24日 · Discover how Sentinel-1 reveals Arctic glacier calving insights, crucial for understanding sea-level rise and climate change.

2024年11月27日 · Significant change to the Arctic and sub-arctic water cycle is underway, impacting hydrologic and biogeochemical fluxes. In southcentral Alaska, glacier mass loss, changes to precipitation (including the rain/snow fraction), thawing ground ice, and vegetation encroachment will change both magnitude and timing of water and solute fluxes downstream.

6 天之前 · Few Canadian glaciers reach the sea and form icebergs. In the Arctic Ocean off northwestern Ellesmere Island there is an area of floating shelf ice that may at one time have been joined by glaciers, but the glaciers no longer reach the sea. This shelf ice has been the principal source of the ice islands of the Arctic Ocean.

3 天之前 · Arctic, northernmost region of Earth, centred on the North Pole and characterized by distinctively polar conditions of climate, plant and animal life, and other physical features. The term is derived from the Greek arktos (“bear”), referring to the northern constellation of the Bear.
Opposed east-west climate response of the Arctic Ocean during …
2024年11月8日 · In the western Arctic, paleoceanographic data demonstrate a linkage between increasing Pacific water fluxes, resulting from the postglacial submergence of the Bering Strait, and the progressive warming, until climate conditions stabilized when sea level reached its present-day limit during the late Holocene.
Striking photos highlight the stark reality of Arctic glacier melt
2024年11月20日 · A pair of photos, taken nearly six decades apart, reveals dramatic ice loss in the Arctic linked to climate change
