van der Kleij, Sylke (author)Atmospheric rivers transport 90% of all atmospheric moisture in the mid-to-high latitudes, while covering only 10% of the Earth’s surface at any given time. Atmospheric rivers occur infrequently, and atmospheric river frequency in the polar areas is especially low, but they can have a large impact on the cryosphere when they make landfall. They...master thesis 2023

LIU, YUSHAN (author)Antarctica plays a crucial role in global climate change research, but current models only extend back to the satellite era from the 1990s to the present, leaving significant gaps in our understanding of the continent’s past and covering only limited locations. Historical aerial surveys, which may extend back to the 1930s and cover more...student report 2023

de Boer, Lotte (author)Icebergs drifting through the Southern Ocean release fresh water and nutrients. This has local impacts on surrounding ecosystems and sea ice formation. On a global scale, salinity patterns and ocean circulation are affected. In addition, <br/> tudying icebergs as a proxy for ice shelves in a warming climate can help predict future climate...master thesis 2023

Chatterjee, Subham (author), Das, Supriyo Kumar (author), Behera, Pravat Kumar (author), Ghosh, D. (author), Chakraborty, Arindam (author), Patel, Priyank Pravin (author), Ikehara, Minoru (author)Variation in leaf colour (green, red and grey) of mosses and lake benthic mats in Antarctica is often linked to water stress and ultraviolet light (UV-B) exposure. Changes in the abundance of organic compounds, such as pectin and phenols, are associated with mechanisms protecting against desiccation and UV radiation. However, the function of...journal article 2023

Nicu, Ionut Cristi (author), Fatorić, Sandra (author)Over the past decade, research on the impacts of climate change on immovable cultural heritage (ICH) in the polar regions (Arctic and Antarctica) has slowly increased. This article offers a systematic review and synthesis of the publications about climate change impacts on the diverse ICH and climate change adaptation in the polar regions....journal article 2023

Schrama, Ernst (author)Ice losses from the Greenland and Antarctic ice sheets have accelerated since the 1990s, accounting for a significant increase in the global mean sea level. Here, we present a new 29-year record of ice sheet mass balance from 1992 to 2020 from the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE). We compare and combine 50 independent...journal article 2023

Dahle, F. (author), Tanke, Julian (author), Wouters, B. (author), Lindenbergh, R.C. (author)A huge archive of historical images of the Antarctica taken by the US Navy between 1940 and 2000 is publicly available. These images have not yet been used for large-scale computer-driven analysis as they were captured with analog cameras. They were only later digitized and contain no semantic information. Most modern deep-learning based...journal article 2022

de Roda Husman, S. (author), Hu, Zhongyang (author), Wouters, B. (author), Munneke, Peter Kuipers (author), Veldhuijsen, Sanne (author), Lhermitte, S.L.M. (author)Surface melt is an important driver of ice shelf disintegration and its consequent mass loss over the Antarctic Ice Sheet. Monitoring surface melt using satellite remote sensing can enhance our understanding of ice shelf stability. However, the sensors do not measure the actual physical process of surface melt, but rather observe the presence...journal article 2022

Hu, Zhongyang (author), Kuipers Munneke, Peter (author), Lhermitte, S.L.M. (author), Dirscherl, Mariel (author), Ji, Chaonan (author), van den Broeke, Michiel (author)Antarctic blue ice areas are exposed due to erosion and sublimation of snow. At the same time, surface melt can form surface types that are spectrally similar to blue ice, especially at low elevations. These are termed melt-induced blue ice areas. Both types of blue ice are sensitive indicators of climate change. Satellite remote sensing is a...journal article 2022

Larour, E. (author), Rignot, E. (author), Poinelli, M. (author), Scheuchl, B. (author)The sudden propagation of a major preexisting rift (full-thickness crack) in late 2016 on the Larsen C Ice Shelf, Antarctica led to the calving of tabular iceberg A68 in July 2017, one of the largest icebergs on record, posing a threat for the stability of the remaining ice shelf. As with other ice shelves, the physical processes that led to...journal article 2021

(author), Kingslake, Jonathan (author), Magruder, Lori A. (author), Wouters, B. (author)Surface melting occurs during summer on the Antarctic and Greenland ice sheets, but the volume of stored surface meltwater has been difficult to quantify due to a lack of accurate depth estimates. NASA's ICESat-2 laser altimeter brings a new capability: photons penetrate water and are reflected from both the water and the underlying ice; the...journal article 2021

Analysing the development of meltwater networks on Antarctica: A casestudy on the Nivlisen ice shelfvan der Zalm, Geerten (author)Meltwater features play an important role in the stability of the Antarctic ice shelves. They can destabilize ice shelves by exerting additional loading forces due to the weight of the water concentrated on one location. However, it is possible that developed meltwater networks transport water from an ice shelf into the ocean. In this way, they...master thesis 2020

van der Linden, S.J.A. (author)Stable boundary layers (SBLs) are a common aspect of the earth’s atmosphere and are characterized by a stable density stratification in which the temperature increases with height. This typically occurs during the night, resulting in a short-lived stable boundary layer, or persistently throughout the polar winter, resulting in a longlived stable...doctoral thesis 2020

Tollenaar, Veronica (author)Meteorites contain information on the formation and evolution of the Solar System. Antarctica is the most productive region for collecting meteorites, as the visually contrasting meteorites are easily detectable and tend to concentrate at specific areas exposing blue ice. Blue ice areas act as meteorite stranding surfaces (MSSs) if the flow of...master thesis 2020

(author)Sea-level rise (SLR) can amplify the episodic erosion from storms and drive chronic erosion on sandy shorelines, threatening many coastal communities. One of the major uncertainties in SLR projections is the potential rapid disintegration of large fractions of the Antarctic ice sheet (AIS). Quantifying this uncertainty is essential to support...journal article 2020
