N-MARINE is a marine-taxa detection and classification dataset collected in 2021 using underwater video cameras mounted on crab pots equipped with lights and bait, deployed at depths of 400–500 m within a small portion of the Northeast Newfoundland Slope Closure. Further details on survey design and acquisition procedures are provided in [1]. The dataset contains 23,936 high-resolution images (1920 × 1080 px; ~1 MB per image; ~30 GB total), each annotated with bounding boxes and species labels. Nine marine species are documented, and images may contain multiple individuals per frame. N-MARINE is a curated subset of 185 videos drawn from a larger corpus of 221 videos originally collected to study the impacts of seismic activity. Each video is approximately five minutes long, recorded at 30 fps. From each video, 1,500 frames were annotated, but only a subset of these annotated frames is included in the open-source release, resulting in a total of 23,936 images in the dataset. A single Fisheries and Oceans Canada (DFO) ecologist annotated all images in DIVE [2], labeling all visible organisms, including partially occluded and truncated individuals. Images are organized by source…
