Automated object detection based on YOLOv11 for monitoring benthic population dynamics: A new approach combining photogrammetry and open‐source GIS tools applied to sea cucumbers

Remote Sensing in Ecology and Conservation, Volume 12, Issue 4, Page 513-530, August 2026.
This research established a new object detection model based on YOLOv11 to recognise benthic organisms, specifically sea cucumbers, by utilising high‐resolution photogrammetric‐based orthomosaics acquired along infralittoral Mediterranean Sea beds. The model demonstrated impressive performance metrics and, when combined with the Deepness plugin for the

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

Archaeological Prospection, Volume 33, Issue 3, Page 621-646, July/September 2026.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Forward Image Registration for Higher Level Interpretation of Zircon Provenance Based on Combined CL, U/Pb Age, and Geochemical Data

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Most detrital zircon studies generate grayscale cathodoluminescence (CL) images, U/Pb dates, and variably extensive trace element concentration data. Yet the combined information contained in these data is rarely used for a higher‐level interpretation of zircon provenance, which still heavily relies on comparison of sample‐wide U/Pb age ...

Reducing Nitrous Oxide Emissions Associated With Fertiliser Using Nitrogen Enriched Biochar

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT There is a need for agricultural practices that decrease nitrous oxide emissions while sustaining yields for food production. In the current paper, we investigate the possibility of reducing emissions by co‐applying or enriching biochar with mineral nitrogen and using it as a fertiliser.
