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.

In this paper we perform laboratory tests and investigate the feasibility to use existing subsea intervention technology, such as manipulator arms to retrieve solid ice samples during under-ice dives of robotic vehicles. This investigation shows, that with minor modifications existing coring technology can be combined with existing subsea technology to provide novel sampling opportunities for submarine ice.

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.
