Tiessen, Nadine (author)In September 2022, Greenland experienced an extraordinary late-season melt event, characterized by temperatures exceeding the melting point at Summit Station for the first time on record and surface melt appearing across one-third of the ice-sheet. This thesis investigates extreme melt events at the Summit in Greenland, focusing on the...master thesis 2023

Trotereau, Jeremy (author)The Greenland Ice Sheet (GrIS) is an ice sheet situated on the island of Greenland. It has a surface area of about 1.74 million km² and contains a volume of ice equivalent to 7.4 m of global mean sea level rise. The GrIS is vulnerable to climate disruptions such as anthropogenic climate change. As a result of increased greenhouse gas emissions,...master thesis 2023

(author), Wouters, B. (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

Kempenaar, Gydo (author)Uncertainty in ice sheet modelling affects centennial and longer time-scale projections of the Greenland Ice Sheet's (GrIS) sea level contribution. One source of this uncertainty is the interaction between the ice sheet’s evolution and the Earth’s deformation in response to changes in the applied surface loading as the ice sheet waxes and wanes....master thesis 2022

Rudlang, Julia (author)The Greenland ice sheet (GrIS) is an important component of the climate system and is a key contributor to future sea level rise, as it is storing frozen water that would raise sea levels by 7.4 m should it all melt (Bamber et al., 2018). Of particular concern is the amount of global warming we are facing now and in the future, as it is becoming...master thesis 2022

The importance of Atlantic Water pathways for understanding glacier discharge in Northwest Greenlandvan Hell, Marije (author)It is well known that warming of deep Atlantic Water in recent decades resulted in extensive retreat of marine terminating glaciers in Northwest Greenland and increased their discharge, which contributed significantly to sea level rise. Here we use data and model resources over a wide range of space and timescales to determine how the pathways...master thesis 2022

(author), Marzeion, Ben (author), Mottram, Ruth (author), van Calcar, C.J. (author)Coastal areas are highly diverse, ecologically rich, regions of key socio-economic activity, and are particularly sensitive to sea-level change. Over most of the 20th century, global mean sea level has risen mainly due to warming and subsequent expansion of the upper ocean layers as well as the melting of glaciers and ice caps. Over the last...journal article 2022

(author)A period of 18 years of infrasonic recordings was analyzed from a microbarometer array (I18DK) in northwestern Greenland, near Qaanaaq. A huge number of infrasonic detections, over 700,000, have been made in I18DKs soundscape during the Arctic summers. Simultaneously identified were both calving events from marine-terminating glaciers and...journal article 2022

Muntjewerf, L. (author)Human-induced climate change is one of the challenges of our time. The increasing global mean temperature, shifts in precipitation patterns, and the rising sea level threaten ecosystems and natural resources, and pose a great risk on society at large. Policymakers need information about the expected impacts, as accurate as possible, in order to...doctoral thesis 2021

Kreynen, Dylan (author)Subsurface firn processes play a crucial role in ice sheet mass loss mechanisms. On Greenland surface meltwater percolates to deeper layers where porous firn retains it, directly inhibiting runoff. However, secondary effects such as the formation of impermeable ice slabs may indirectly and irreversibly accelerate runoff and with it global sea...master thesis 2021

Sellevold, R. (author)One of the major consequences of ongoing global warming is the melting of the Greenland ice sheet (GrIS). The GrIS, as the world’s second largest freshwater reservoir, has the potential to raise sea levels by 7.4 m (Bamber et al., 2018a,b). Such a sea level rise would have a devastating effect on coastal societies, where a large fraction of...doctoral thesis 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
