ROV imagery from the Gascoyne Marine Park

This record describes Remotely Operated Vehicle (ROV) imagery collected from within the Gascoyne Marine Park offshore northwestern Australia.The ROV SuBastian was used to conduct imagery transects on 20 dives across 16 stations, including 12 quantitative transects within the Cape Range Canyon. No quantitative transects were conducted in the Cloates Canyon due to delays caused by poor weather. SuBastian is equipped with a Sulis Subsea Z70 deep sea science camera, with 4K UHD 2160p optics and sensors for temperature, depth, conductivity and oxygen. The quantitative transects were run for 500 m upslope, ideally at a speed of 0.3 knots and an altitude of 2 m above the seafloor or rock walls. Still images were acquired every 5 seconds, with additional frames added manually as required.Still images from most transects were primarily annotated onboard using the RV Falkor’s private instance of SQUIDLE+, with some post-survey annotation conducted using the public instance of Squidle+ (http://squidle.org/).See post-survey report for full methodology.http://pid.geoscience.gov.au/dataset/ga/144204

本数据集记录了采集自澳大利亚西北近海加斯科因海洋公园（Gascoyne Marine Park）内部的遥控水下机器人（Remotely Operated Vehicle, ROV）影像数据。
本次调查使用SuBastian号遥控水下机器人，在16个站位开展了20次成像断面巡航，其中包含开普岭峡谷（Cape Range Canyon）内的12条定量成像断面。受恶劣天气引发的延误影响，克洛特斯峡谷（Cloates Canyon）区域未开展任何定量断面调查。
SuBastian号搭载Sulis Subsea Z70深海科学相机，配备4K超高清2160p光学系统，以及温度、深度、电导率与溶解氧传感器。
定量成像断面沿上坡方向布设，单段长度为500米，理想航速为0.3节，作业高度为距海底或岩壁2米。
静态图像以每5秒1张的频率采集，同时可根据需求手动追加额外帧。
大部分断面的静态图像主要在Falkor号远洋科考船（RV Falkor）上，通过其搭载的SQUIDLE+私有实例完成机载标注；部分后期标注工作则通过Squidle+公共实例（http://squidle.org/）开展。
