Side scan sonar and swath bathymetry collected along OFOBS profiles during POLARSTERN cruise PS124

The Ocean Floor Observation and Bathymetry System (OFOBS), used during Polarstern research cruise PS124 to the southern Weddell Sea , a towed underwater camera system equipped with both a high-resolution photo-camera (iSiTEC, CANON EOS 5D Mark III) and a high-definition video-camera (iSiTEC, Sony FCB-H11). The cameras were mounted on a steel frame (150L x 92W x 105H cm), together with two strobe lights (iSiTEC UW-Blitz 250, TTL driven), three parallel laser pointers spaced with a distance of 50 cm used to estimate the size of seafloor structures, four LED lights, and a USBL positioning system (Posidonia) to track the position of the OFOBS during deployments. Additionally mounted on the platform was an EdgeTech 2205 bathymetric side scan and BlueView M900-130 forward looking sonar systems, to become the Ocean Floor Observation and Bathymetry System (OFOBS). Auxiliary sensors include an iXBlue PHINS 6000, and an AML Micro-X 6000 SV-Xchange sound velocity probe. An iXBlue DVL system was installed to augment the output of the PHINS 6000. […]

极地研究船 Polarstern 在执行前往南威德尔海的 PS124 考察任务期间，所使用的海洋底部观测与测深系统（OFOBS），该系统配备了一台高分辨率相机（iSiTEC，CANON EOS 5D Mark III）和一台高清摄像机（iSiTEC，Sony FCB-H11）。相机固定在一个150L x 92W x 105H 厘米的钢制框架上，并配备了两个闪光灯（iSiTEC UW-Blitz 250，TTL 控制），三个间距为 50 厘米的平行激光指示器，用于估算海底结构的大小，四个 LED 灯，以及一个 USBL 定位系统（Posidonia），以跟踪 OFOBS 部署过程中的位置。此外，平台上还安装了 EdgeTech 2205 海底测深侧扫系统和 BlueView M900-130 前视声纳系统，共同构成了海洋底部观测与测深系统（OFOBS）。辅助传感器包括 iXBlue PHINS 6000 和 AML Micro-X 6000 SV-Xchange 声速探测仪。为了增强 PHINS 6000 的输出，还安装了一个 iXBlue DVL 系统。
