First evidence of live mesophotic coral reefs on the Benin continental shelf
Recent marine surveys off the coast of Benin have yielded the first confirmed visual evidence of living mesophotic coral ecosystems (MCEs) within the Gulf of Guinea—a region previously presumed devoid of such habitats. Utilizing side-scan sonar and underwater video, researchers documented thriving octocoral communities at depths of 54 meters, forming a unique mesophotic coral garden. This discovery, spanning approximately 7 kilometers, significantly expands our understanding of West African marine biodiversity and underscores the urgent need for further exploration and baseline data collection.
PICOGRAM - informing coral reef resilience-based management through prediction of individual coral organismal growth, recruitment, and mortality
PICOGRAM introduces a novel, open-source framework for scalable coral reef monitoring, addressing the limitations of manual annotation in image-based assessments. Inspired by the NASA NeMO-Net ecosystem, PICOGRAM leverages a Segment Anything Model (SAM) to automate coral colony detection and percent-cover estimation from underwater imagery and orthomosaics. Evaluated against expert annotations, PICOGRAM achieves high accuracy (IoU 87.5% in-domain) and calibrated quality scores, enabling efficient refinement with minimal user input.
