Summary: | The Ocean Floor Observation System (OFOS), used during Polarstern research cruise PS101 to the Langseth Ridge in the Central Arctic, was 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 OFOS during deployments. For PS101 the OFOS was upgraded with a 85 cm tail to additionally mount 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, an AML Micro-X 6000 P-Xchange pressure sensor and an AML Micro-X 6000 ... : Some post processing software does not recognize the recorded vehicle depth. For additional depth correction, the INS log is attached.Offset from Sonar to Navigation Reference# x: Forward# y: Starboard# z: Vertical positive upx,y,z = 0.507,-0.006,0.212 ... |
