The paper introduces the design and data acquisition system of the instrument named Snow Terrain and Mobility Evaluation Tool (STMET). As a multipurpose instrument, STMET will purge the hauling of separate equipment during the movement in the difficult snow-bound regions helping in easy mobility and collection of crucial parameters for avalanche defence. The instrument presented in this paper can replace traditional instruments like Cone Penetrometers, Ramsonde and even SnowMicropen.

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 properties diversity, offering insights into this unexplored region.

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. 

Our research introduces a 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 RECAS by adjusting the drill's heat distribution and the results of the experiments.

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 manuscript that 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 non-research vessels to reduce costs and broaden the scope of applications.
