Summary: This study investigates the potential of towed underwater camera systems with tightly coupled GNSS positions to create detailed bathymetric models of reefs using SfM photogrammetry. By mapping complex shallow reef environments without the need for ground control points, this technique enables accurate assessments of benthic conditions. The use of multiple synchronized cameras improves mapping coverage and allows for wider survey line spacing, resulting in sub-millimeter accuracy for local length measurements and reproducible bathymetry at the scale of GNSS accuracy.

Summary: The use of structure-from-motion, multi-view stereo (SfM-MVS) in the mining industry is well-established for capturing digital data on surface. However, applying SfM-MVS in active underground mining faces unique challenges like preparation time, camera positioning, illumination and useability. Utilizing SfM-MVS allows for remote mapping of underground development, enhancing productivity and safety.

Summary: Glacier calving fronts are dynamic environments that are becoming more common as glaciers recede and develop proglacial lakes. Monitoring these fronts is essential for understanding glacier ablation and warning nearby communities of potential hazards. Researchers have developed a low-cost camera system using Raspberry Pi computers that can generate accurate 3D models of glaciers, providing a practical option for future scientific research and possible early warning systems for glacial lake outburst floods.

Summary: Geodetic methods are crucial for mapping surface and subsurface objects and phenomena. In the case of ice caves, traditional techniques like terrestrial laser scanning may not accurately capture the surface due to the ice's physical properties. This study proposes using cross-polarized Structure-from-Motion photogrammetry to overcome this limitation and obtain high-quality surface data.

Summary: This study utilized UAV surveys and SfM photogrammetry to evaluate the performance of an artificial gravel beach exposed to various external forces, including storms. The results showed that the beach experienced the largest changes after the first storm following nourishment, with most sediment loss occurring on the east side. However, overall changes in beach volume and area were relatively small, indicating the stability of the artificial beach. The study emphasized the importance of considering pocket embayed beaches in three dimensions and highlighted the potential of UAVs and SfM for high-resolution elevation change studies and coastal monitoring of beach nourishment.

Summary: Small glaciers in temperate mountain regions have experienced significant reduction and unprecedented melt rates in recent years. Some glaciers have transitioned from clean ice to debris-covered or even rock glaciers. This study examines the surface elevation change of the Popera Alto glacier in the Sesto Dolomites using LiDAR and Structure from Motion surveys, and analyzes its evolution in terms of surface cover and geomorphic processes. The glacier has lost an average of 0.35 m water equivalent per year over the past 16 years, with active modification of its surface cover by geomorphic processes. The role of debris and local topography feedback has allowed the resilience of the glacier, leading to a marked difference between the current environmental equilibrium line altitude (envELA) and the effective ELA (effELA) of the glacier.

Summary: In this study, we investigated a large slow-moving landslide in Northern Pakistan, using Interferometric Synthetic Aperture Radar (InSAR) analysis. Our results showed that the crown of the landslide is moving faster than the surrounding regions, while the footslope experienced high deformations. We discussed the possible roles of meteorologic and anthropogenic factors in causing these deformations.

Summary: The Yarlung River's drainage divide is primarily moving north due to variations in precipitation across the Himalayas. The Gangdese drainage divide shows predominantly northward and southward migration, controlled by base-level rise and downstream influences. The presence of north-trending rifts separates the drainage divides into five zones, each with a distinct migration pattern.

Summary: The study investigates the relationship between glacial dynamics and lake sedimentation during the mid-Holocene climate variability in the Southern Zanskar ranges. It utilizes geomorphological disposition, elemental geochemistry, and optical chronology of relict lake sediment to reconstruct the pattern of minor glacier responses to climate variability. The results indicate six centennial to millennial-scale climatic phases, with warmer phases represented by decreased mineralogical fine grain flux and increased coarse grain flux. The study highlights the potential of relict lake sediment and para/peri-glacial landforms in understanding glacial dynamics and climate change during the Holocene.

Summary: In this study, an approach combining various data and observation methods was proposed to improve the monitoring of landfast ice dynamics and its geomorphic impact on sedimentary systems. The results demonstrate the ability of the approach to accurately measure interannual variations in landfast ice and constrain geomorphic changes. Additionally, the study found a strong relationship between the severity of freezing seasons and the response of landfast ice to hydrometeorological events, with different geomorphic responses observed under different winter conditions.

Summary: Granule ripples are aeolian landforms armored against erosion by coarse grains. This study investigates their seasonal morphological evolution and migration in the Sanlongsha Dune Field. The findings show that wind events, especially those exceeding the threshold velocities of coarse grains, significantly influence the morphodynamics of granule ripples. The study highlights the importance of considering the reptation and saltation of coarse grains in future research on granule ripples.
