Summary: Glacial lakes in the Himalayas are rapidly increasing and contribute significantly to the atmospheric carbon dioxide levels. However, our understanding of the carbon cycling in these lakes is limited, which hinders our ability to predict their impact on the carbon budget.

Summary: The aim of this study was to identify possible causes of thickness changes for Himalayan debris-covered glaciers. The results showed that the thickness changes were mainly influenced by debris thicknesses, ice cliffs and supraglacial lakes, with different dominant factors for different regions.

Summary: Retrieving glacier ice thickness is crucial for monitoring water resources and predicting glacier dynamics and changes. This study estimates the ice thickness of High Mountain Asia glaciers using a flow model and remote sensing techniques, highlighting the issues related to velocity-based thickness inversion. The inclusion of velocity influencing parameters in physical-based models is suggested for accurate ice thickness inversion.

Summary: The study improved glacial lake datasets in High Mountain Asia by producing accurate maps in 2008, 2012, and 2016, showing an annual areal expansion rate of 1.38% from 2008 to 2016. The rapid expansion of glacial lakes, mainly near glaciers, is attributed to accelerated glacier melting due to global warming.

Summary: This article introduces Matchete, a computer tool for matching weakly-coupled models at one-loop order. It can directly compute all matching contributions and simplify redundant operators from the output. This tool is crucial for studying the impact of new-physics models on low-energy observables.

Summary: Iceberg calving is a significant factor contributing to mass loss from the Greenland Ice Sheet. A highly automated workflow using high spatial resolution ArcticDEM data was developed to detect icebergs and append their associated metadata within Google Earth Engine. The study analyzed three glaciers and successfully detected a large number of icebergs, contributing to insights into iceberg distributions and their impact on glacier mass loss and fjord freshwater fluxes. The workflow offers the potential to interrogate iceberg data on a pan-Arctic scale.

Summary: The study simulated the subglacial topography in the Austrian Alps and found that the current models overestimate the number and location of potential future glacial lakes, especially in valley type glaciers. The research suggests that the modeling approach performs better on large valley type glaciers and less accurately on mountain glaciers. The results indicate that up to 42 new lakes may form within 23 glaciers in Austria.

Summary: A concept map is a pedagogical tool that helps students understand concepts and correct misconceptions. This paper introduces Cronus, a system that evaluates student concept maps by comparing them with instructor concept maps and provides useful feedback, automatically suggesting the correct grades.

Summary: The research team developed a flexible, web-based semi-automated data extraction tool called Dextr, successfully addressing data extraction challenges in environmental health literature reviews. By integrating key features such as user verification and entity connecting, the Dextr tool significantly reduces data extraction time while maintaining recall and precision rates similar to manual extraction.

Summary: In this paper, the angle-resolved optically detected magnetic resonance (ODMR) technique is used to study strained (Cd, Mn)Te/(Cd, Mg)Te quantum wells. The strain-induced axial-symmetry spin Hamiltonian parameter D is determined through analysis of ODMR angular scans, and the local strain present in the QW material is evaluated using low-temperature optical reflectivity measurements and x-ray diffraction scans.
