Seafloor images and raw context data along AUV track SO239_193-1_AUV18 (Abyss_184) during SONNE cruise SO239

The images in this dataset have then been undistorted to virtual images that an ideal perspective camera with only 90 degrees horizontal field of view would have seen from the same position. To achieve this, the color of each pixel in the ideal image is obtained by […]
