Abstract:
The need to gather data in such a harsh, isolated, and hard-to-access environment as Antarctica is a priority for the scientific community aiming to understand this system's responses to different climate change scenarios. FosterCoast is a dataset collected using a UAV-based LiDAR sensor during the Spanish Antarctic Campaign 2024-2025 (Austral summer 2025), covering the entire inner ring (~35 km) of Port Foster Bay on Deception Island (Antarctica). It comprises the original data along with topographic products - such as orthomosaics, DEMs, and point clouds - derived from the photogrammetric processing of 13 UAV surveys, which include a total of 5,631 high-resolution RGB captures with Post-Processing Kinematic positioning. FosterCoast, available for public download via the Figshare data repository, represents the first complete UAV-based survey covering the entire Port Foster Bay within the volcanic ecosystem of Deception Island. This highly detailed dataset is a valuable asset for the polar scientific community, as well as for other relevant sectors, including the rescue operations, tourism, and navigation.

In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
