This work presents simulations, modelling, and experimental verification of a novel steady-state surface nuclear magnetic resonance (NMR) transmitter used for the non-invasive exploration of groundwater. The paper focuses on three main aspects of high-current transmitter instrumentation: thermal management, current-drooping, and pulse stability. This work will interest readers involved in geoscientific instrument prototyping for groundwater exploration using portable geoscientific instruments.

Humidity sensors that function under extreme conditions are needed in experimental chambers as well as for humidity measurements on Mars. Such a sensor was already used in a chamber at the German Aerospace Center and is well characterized; however this sensor is no longer in production and has been replaced by a new generation, requiring verification of the new sensor under extreme conditions. The results show that the new sensor is suitable for measurements under Martian atmospheric conditions.

The development and characterization of a ground-based system measuring column average concentrations of greenhouse gases is described, as well as the corresponding four years dataset recorded at Harwell, Oxfordshire, UK. The system, based on high-resolution Fourier Transform spectroscopy of atmospheric transmission, fulfills the requirements established by the Total Carbon Column Observatory Network (TCCON) to contribute to the international greenhouse gas observing infrastructure.

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.

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 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.

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.
