Image annotation data from baited camera lander deployments on the Cabo Verde Abyssal Plain

A total of eight deployments of an autonomous baited camera lander were conducted at the Cabo Verde Abyssal Plain (tropical East Atlantic, Lat. 14.72, Lon. -25.19, Water depth ~4200 m) using either Atlantic mackerel (Scomber scombrus, n=4) or Patagonian squid (Doryteuthis gahi, n=4) bait, to photograph organisms attracted to the bait over roughly 24 hours. The deployments took place during the iMirabilis2 campaign in August 2021 from the research vessel Sarmiento de Gamboa. A deep-sea time lapse camera system with an oblique view of the bait plate (12 cm x 45 cm) and surroundings took a picture every 150 seconds. The bar attached to the bait plate is 6 cm wide. The camera was located about 120 cm above the seafloor with an oblique view of 40 degrees (assuming straight down in 0 degrees). Annotations were performed in BIIGLE software (Langenkämper et al. 2017) on every second photograph, providing the morphospecies group label (or 'No ID' if to morphospecies level was not possible) and the taxonomic hierarchy to a level of best confidence for each annotation. Annotations were rectangular in shape, enclosing each individual so that the centre of the annotation was roughly the centre of mass, and the points of each rectangle corner are provided in pixels (x,y) where the lower left corner of the picture is 0,0. Images were 6000 pixels in width and 4000 pixels in height.

本研究共在佛得角深渊平原（热带东大西洋，纬度14.72°，经度-25.19°，水深约4200米）开展8次自主诱饵相机着陆器布放作业，诱饵分别选用大西洋鲭（Scomber scombrus，n=4）与阿根廷鱿鱼（Doryteuthis gahi，n=4），每组各4次布放，旨在记录时长约24小时内被诱饵吸引的深海生物。本次布放作业依托“萨尔米恩托·德·甘博亚”号（Sarmiento de Gamboa）科考船，于2021年8月随iMirabilis2科考航次实施。实验搭载具备诱饵盘（12 cm × 45 cm）及周边环境斜向拍摄视角的深海延时摄影系统，每150秒采集一张图像；诱饵盘附带的固定横杆宽度为6厘米。相机安装于距海底约120厘米处，拍摄斜角为40°（以垂直向下为0°基准）。所有标注工作均通过BIIGLE软件（Langenkämper等，2017）完成，对每隔一张的图像进行标注：为每个观测对象赋予形态种群组标签（若无法鉴定至形态种水平则标注为“No ID”），并以最高置信度标注至对应的分类层级。标注框采用矩形格式，需完全包围单个观测个体，且标注框中心与个体质心大致重合；各角点以像素坐标(x,y)形式给出，图像左下角为坐标原点(0,0)。单张图像的分辨率为6000像素（宽）×4000像素（高）。

背景与挑战

背景概述

该数据集包含2021年8月在卡博维尔德深海平原（热带东大西洋，水深约4200米）使用诱饵相机着陆器获取的图像标注数据，旨在研究深海食腐生物群落。数据涵盖八次部署，使用两种诱饵（鱼和鱿鱼），每150秒拍摄一张照片，并通过BIIGLE软件对图像进行标注，提供形态种分类和个体边界框坐标。数据集特点是聚焦深海生态系统，包含高分辨率图像（6000x4000像素）和详细的生物标注信息。
