Underwater videos and sea cucumber annotations from the survey HOLOTVSPM2025

In response to the increase in landings of Cucumaria frondosa in Saint Pierre and Miquelon, Ifremer has developed an underwater video surveillance programme to improve knowledge of local populations and assess their biomass, with the aim of proposing a sustainable management plan. Four annual surveys (2021, 2022, 2023, 2025) have been conducted in the archipelago's Exclusive Economic Zone (EEZ). Each survey is based on a renewed sampling plan, using a GoPro camera equipped with two LED lights attached to a modified sea cucumber dredge, enabling standardised videos of the seabed to be acquired. This leads to a unique set of videos that give information about the sea floor with the flora and fauna associated in the Saint-Pierre and Miquelon waters. This dataset present the videos realised in the 2025 survey (mp4 format) and the annotions of the sea cucumbers seen during the survey (json format). The database also includes 2 text files with semicolon-separated values. The first file (01_data_summary.csv ) contains a description of the records and a summary of the annotation process. The second file (02_coordinates_summary.csv ) contains information on the GPS positions of the video recording. The dataset is accompanied by a README.md file that (i) outlines the directory hierarchy, (ii) describes the naming convention for video and annotation files, and (iii) details the information provided by the files.
