Metadata

The IBCSO is realized by a strong international collaboration with a great number of individual scientists, national data centers, and international scientific programs. Multibeam and single beam data are integrated as well as topographic information, satellite data, and marine gravity data.

Bathymetric data are acquired over a long-term period. Therefore, data errors and inconsistencies occur and need to be corrected. Starting with raw data, the database will contain derived data like grids, contour lines, and preliminary maps. Beside the original data sets and track control, we need additional information to be provided by the data producers:

who produced the data set, who are the originators and distributors?
what kind of bathymetric data is provided - multibeam, narrow single beam, sidescan, ...?
when was the data set created?
how was the data set created?
how was the data set generated, processed, and modified?
how reliable are the data in terms of accuracy?
definition of work areas and boundaries?
what data coverage of the work area is achieved?
why was the data set created, motivation for data acquisition?
are there legal restrictions on access or use?
contact persons to be named (coordinator, data manager, data archivist)

These informations are necessary to fulfill the Metadata-Standards of the International Organisation for Standardisation (ISO) TC211. Open an exemplary metadata xml-file prepared by the Bathymetry Group of the Alfred Wegener Institute for Polar and Marine Research.

Echo Sounding Data

Important note: enable us to complete the IBCSO database with available digital data, charts, contours, grids, ASCII data, and other relevant information. This improves the quality of the IBCSO for the benefit of all.

Topographic Data of Antarctica

Topographic data of the Antarctic continent comprises a complete digital elevation model, which is compiled from various data sources acquired over a long peroid. Topgraphic data are also provided by a great number of facilities and data centers, which is gratefully acknowledged.

Additional Data

Global data sets are derived from marine gravity and satellite altimetry displaying bathymetry and topography. Additional data from bathymetry, geology, and geophysics are provided by a great number of facilities and data centers, which is gratefully acknowledged.
