The main objective of the IBCSO was therefore to create the �rst seamless digital bathymetric model (DBM) of the Southern Ocean comprising all available bathymetric data from various sourc- es around the globe. IBCSO version 1.0 is covering the area south of 60° S with a resolution of 500 m x 500 m based on a polar stereo- graphic projection with true scale at 65° S. An Editorial Board was established that collectively gathered more than 4 000 million echosounding points from more than 30 institutions, in 15 di�er- ent countries. All contributed data sets have been transformed into a generic ASCII XYZ data format, including weighting fac- tors and unique source identi�cation codes as point attributes. The DBM then was derived using an iterative process of grid- ding and cleaning the data. IBCSO retrieval: The IBCSO products, DBM and an adjacent map, are going to be publically available by spring 2013 via and via the data portal PANGAEA.
