Abstract:
Swath sonar bathymetry data of the AUV ABYSS (GEOMAR) was recorded during RV POSEIDON cruise POS510 in March 2017 for the project "ANYDROS: Rifting and Hydrothermal Activity in the Cyclades Back-arc Basin". Chief Scientist was Prof. Mark Hannington from GEOMAR Helmholtz Centre for Ocean Research Kiel. The cruise took place between 2017-03-06 and 2017-03-29 in the Mediterranean Sea near Santorini, Greece. The cruise report is available under the following url: https://oceanrep.geomar.de/id/eprint/44466
The data was acquired during seven AUV dives at Kolumbo Seamount (NE of Santorini Island) by AUV ABYSS using a Kongsberg RESON Seabat 7125 Multibeam system run with a frequency of 200 kHz. Data were manually edited for false measurements in the software Qimera. No further artificial sound velocity profiles were used during processing. The data of the individual dives was combined, gridded at 2m resolution and the midpoints exported as txt-file with Latitude and Longitude provided in WGS84 datum and depth with negative values.
