A new ground-based technique is described, called distance of flight of cosmic-ray muons, for sensing the height of the layer of the Earth where cosmic-ray muons are generated, called the muopause, which is closely related to the height of the tropopause and lower stratosphere.

Under German law, crack damage stress must not be reached at any time during the operation or post-closure phase of a nuclear waste repository. This legal requirement can only be fulfilled if the parameter can be measured precisely. We have thus developed a new measurement technique, which overcomes the limitations of the conventional method. In combination, old and new methods offer an easy procedure to detect crack damage stress in fully saturated rocks in a fast and robust manner.

Our research introduces technology for exploring subglacial lakes while keeping them isolated from surface contamination. The RECoverable Autonomous Sonde (RECAS) can drill ice both downward and upward, allowing clean water sampling. In some cases, the sonde should drill at specific angles to follow a trajectory, maintain verticality, or bypass obstacles. This paper describes the general principles of steering the RECAS by adjusting the drill's heat distribution and the experimental results.

This research aims to tackle the issue of inconvenient clock synchronization in marine controlled-source electromagnetic (MCSEM) operations with coaxial cables. This clock synchronization method in the paper can be applied to scenarios where coaxial cables are used for MCSEM operations. We hope that in the future, MCSEM transmitters can be deployed on a wider variety of ships to reduce costs and broaden the scope of applications.

We developed a software system for a high-precision magnetometer platform, specifically designed for human-occupied vehicles (HOVs). The system integrates magnetometers to deliver accurate magnetic field detection, with advanced features such as automatic probe switching and magnetic compensation. The system's performance was validated through rigorous laboratory tests and marine experiments on the Shenhai Yongshi platform. 

This work explores the use of aerial photography surveys for mapping glaciers, specifically in challenging environments. Using examples from two glaciers in Arctic Canada, we discuss the main factors which can affect data collection and review methods for capturing and processing images to create accurate topographic maps. Key recommendations include choosing the right camera and positioning equipment and adapting survey design to maximise data quality, even under less-than-ideal conditions.

Our study investigated the influence of plant processes on oxygen dynamics, crucial for paleoclimatology. By examining maize respiration and photosynthesis using advanced techniques, we enhanced our understanding of past climates through ice core analysis.

This publication presents data from geophysical measurements taken in the Rospuda wetlands in NE Poland using the electrical resistivity imaging (ERI) method. The study aimed to provide the material for illustration of the arrangement of geological layers creating the wetland. The data can help develop models of groundwater and surface water contact as well as improve understanding of the area's geomorphology with soil property diversity, offering insights into this unexplored region.
