Geological interpretation of bathymetric and backscatter data

The Geomar Helmholtz Centre for Ocean Research Kiel carried out two cruises in the eastern equatorial Pacific back in 2015 and collected multibeam, backscatter and sub-bottom data along with other oceanographic information. This work focuses on the evaluation and processing of the echo sounder data sets. Wrong measurements encountered during the data processing are analysed and corrected. A geological classification and interpretation of the seafloor by using the ArcGIS tool »Benthic Terrain Modeler« and an algorithm for Principal Component Analysis and K-means clustering. Classifying the seafloor helps to identify pit structures lining the seafloor which possibly formed due to dissolutions in the seabed.
