Investigating firn structure and density in the accumulation area of the Grosser Aletschgletscher using ground-penetrating radar Open
The role of firn structure and density in geodetic glacier mass balance estimation has been constrained, with studies in alpine conditions primarily relying on models. Our research focuses on understanding the firn structures, density, and…

Modelling the future evolution of an alpine debris-covered glacier Open
Debris-covered glaciers can react differently to external forcings than clean-surface glaciers. Depending on its thickness, a supraglacial debris layer impacts the glacier mass balance by either enhancing the surface melt or protecting the…

Discharge characteristics for different glacier mass balance conditions at Vernagtferner, Ötztal Alps Open
Discharge from glaciers plays an important role for ecosystems, land use and hydropower production in different regions of the world. The discharge hydrograph in glaciated catchments is determined by several parameters, like snow cover, gl…

Beyond SOT: Tracking Multiple Generic Objects at Once Open
Generic Object Tracking (GOT) is the problem of tracking target objects, specified by bounding boxes in the first frame of a video. While the task has received much attention in the last decades, researchers have almost exclusively focused…

AVisT: A Benchmark for Visual Object Tracking in Adverse Visibility Open
One of the key factors behind the recent success in visual tracking is the availability of dedicated benchmarks. While being greatly benefiting to the tracking research, existing benchmarks do not pose the same difficulty as before with re…

Transforming Model Prediction for Tracking Open
Optimization based tracking methods have been widely successful by integrating a target model prediction module, providing effective global reasoning by minimizing an objective function. While this inductive bias integrates valuable domain…

Robust Visual Tracking by Segmentation Open
Estimating the target extent poses a fundamental challenge in visual object tracking. Typically, trackers are box-centric and fully rely on a bounding box to define the target in the scene. In practice, objects often have complex shapes an…

Comment on tc-2021-305 Open
Abstract. The Ekström Ice Shelf is one of numerous small ice shelves that fringe the coastline of western Dronning Maud Land, East Antarctica. Reconstructions of past ice-sheet extent in this area are poorly constrained, due to a lack of …

Performance of ALICE AD modules in the CERN PS test beam Open
Two modules of the AD detector have been studied with the test beam at the T10 facility at CERN. The AD detector is made of scintillator pads read out by wave-length shifters (WLS) coupled to clean fibres that carry the produced light to p…

Surges of Harald Moltke Bræ, north-west Greenland: Seasonalmodulation and initiation at the terminus Open
Harald Moltke Bræ, a marine-terminating glacier in north-west Greenland, shows episodic surges. A recent surge from 2013 to 2019 lasted significantly longer (6 years) than previously observed surges (2–4 years) and exhibits a pronounced se…

Quantifying the effect of ocean bed properties on ice sheet geometryover 40,000 years with a full-Stokes model Open
Simulations of ice sheet evolution over glacial cycles requires integration of observational constraints using ensemble studies with fast ice sheet models. These include physical parameterisations with uncertainties, for example, relating …

Passive room conditioning using phase change materials—Demonstration of a long‐term real size experiment Open
The thermal properties of lightweight buildings can be efficiently improved by using phase change materials (PCMs). The heat storage capacity of the building can be extended exactly at the desired temperature level, which leads to an enorm…

Glacial cycle ice-sheet evolution controlled by ocean bed properties Open
<p>Shortcomings in the description of ice dynamics have been recognized as a major limitation for projecting the evolution of the Greenland and Antarctic ice sheets. If current sea-level rise rates continue unabated, up to 630 millio…

Kinematic response of ice-rise divides to changes in oceanic andatmospheric forcing Open
The majority of Antarctic ice shelves are bounded by grounded ice rises. These ice rises exhibit local flow regimes that partially oppose the flow of the surrounding ice shelves. Formation of such ice rises is accompanied by a characterist…

Report from Working Group 5 Open
The future opportunities for high-density QCD studies with ion and proton beams at the LHC are presented. Four major scientific goals are identified: the characterisation of the macroscopic long wavelength Quark-Gluon Plasma (QGP) properti…

The Rofental: a high Alpine research basin (1890 m – 3770 m a.s.l.) in the Ötztal Alps (Austria) with over 150 years of hydro-meteorological and glaciological observations Open
A comprehensive hydrometeorological and glaciological data set is presented, originating from a multitude of recordings at several intensively operated research sites in the Rofental (1891–3772 m a.s.l., Ötztal Alps, Austria). The data set…
