Two geo-referenced photo mosaics (GeoTIFF, UTM 16S) generated from AUV camera surveys conducted during cruise SO242_1 (Abyss196_SO242/1_83_1; Abyss199_SO242/1_102_1) in the center of the DEA are available here.

The photos were acquired by AUV ABYSS (REMUS 6000 Type) in two different surveys: During Abyss196_SO242/1_83_1 (line spacing 5 m) photos were acquired in 7 m altitude, whereas during Abyss199_SO242/1_102_1 (line spacing 4 m) the survey altitude was decreased to 4.5 m for increased resolution. The mosaics were geo-referenced using the ArcGIS 10.2 Georeferencing Toolbox based on the AUV-acquired Side Scan Sonar map (https://doi.pangaea.de/10.1594/PANGAEA.905617). The plough marks resolved in the hydro acoustic and optical data were used as reference features. The images from the two photo surveys and their context data are available under https://doi.org/10.1594/PANGAEA.881948 (for Abyss199_SO242/1_102_1) and https://doi.org/10.1594/PANGAEA.881896 (for Abyss196_SO242/1_83_1).
