10 - A novel Structure from Motion-based approach to underwater pile field documentation.
Authors: Johannes Reich, Philipp Steiner , Ariane Ballmer, Lea Emmenegger, Marco Hostettler, Corinne Staheli, Goce Naumov, Bojan Taneski, Valentina Todoroska, Konrad Schindler, & Albert Hafner. This article presents a novel methodology for the underwater documentation of pile fields in archaeological lakeside settlement sites using Structure from Motion (SfM). Mapping the piles of such sites is an indispensable basis for the exploitation of the high-resolution absolute chronological data gained through dendrochronology. In a case study at the underwater site of Ploca, Micov Grad at Lake Ohrid, North Macedonia, nine consecutive 10 m2 strips and a 6 m2 excavation section were uncovered, the situation documented, and the woodpiles sampled.

2 - A Shallow Water Ferrous-Hulled Shipwreck Reveals a Distinct Microbial Community.
Authors: Kyra A. Price, Cody E. Garrison, Nathan Richards, and Erin K. Field Shipwrecks serve as artificial reefs and offer a surface for various life forms, especially microbial communities. This study focused on the Pappy Lane shipwreck to assess microbial community differences. Samples showed shipwreck microbes were more similar to each other than to surrounding environments. Variations were noted in microbial communities on corroded versus non-corroded debris. Iron-oxidizing bacteria linked to deterioration were abundant on corroded samples. A new strain was isolated and found to potentially support nutrient cycling in the ecosystem. Understanding these communities can aid in shipwreck preservation efforts.
