ADCP data measured during 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 and surroundings took a picture every 2.5 min. An ADCP (Aquadopp 6000 m, Nortek) mounted on top of the lander frame took a reading of near bottom currents (~2 meter above bottom) every second. This dataset includes the data downloaded from the ADCP current meter.

本研究于佛得角深海平原（热带东大西洋，纬度14.72°，经度-25.19°，水深约4200米）开展8次自主式诱饵摄像着陆器部署作业，分别以大西洋鲭（Scomber scombrus，n=4）与巴塔哥尼亚鱿鱼（Doryteuthis gahi，n=4）作为诱饵，在约24小时的观测周期内拍摄被诱饵吸引的海洋生物。本次部署于2021年8月的iMirabilis2科考航次中完成，搭载平台为“萨尔米恩托·德·甘博亚”号（Sarmiento de Gamboa）科考船。配套的深海延时摄像系统具备诱饵盘及周边环境的斜向拍摄视角，每2.5分钟采集一张图像；安装于着陆器框架顶部的声学多普勒流速剖面仪（ADCP，Aquadopp 6000 m，Nortek）每秒采集一次近底水流数据，采集高度距海底约2米。本数据集包含从该ADCP海流计下载的全部观测数据。
