Abstract:
Five georeferenced seafloor photomosaics from three different cold seep sites in the periphery of Venere mud volcano, Ionian Sea (Central Mediterranean).
The photographs for each mosaic were acquired using the remotely operated vehicle (ROV) MARUM QUEST 4000m during RV METEOR cruise M112 (2014). Photos were taken from altitudes 1-5 m above seafloor using a Prosilica GT6600C camera vertically mounted on the ROV. The photomosaics were compiled with the LAPM tool (Marcon et al. 2013) and geo-referenced by using the smoothed ultra-short baseline (USBL; IXSEA Posidonia 6k) navigation data of the ROV. Seafloor positioning by USBL has an accuracy better than 10 m, or 0.05-0.2% of the slant range. Photomosaics have been rectified manually in Global Mapper® software based on obvious seafloor structures and are provided in GeoTIFF format (WGS84 coordinate system).
