20250328 16284100 1.0 TRUE Visual Surveys This polyline dataset provides one entry per survey for 2014 only. Surveys for other years will be added and updated in 2017. All data are based on the dive log entries using the appropriate syntax for surveys. Positioning is given by the navigation sensors of the ROV ranging between 1Hz and 5Hz, depending on availability. The trackline is based on the interpolation of raw data with some major outliers removed. The navigation sensors may have occasionally lost contact with the ship due to range or noise issues, which can cause some outliers or gaps in the data.
