ALL MARINE BATHYMETRY DATA ARE WELCOME!

If you would like to contribute data to the next version of the global topography grid we would be pleased to use it. Any format is welcome, even raw multibeam formats. For our next version we plan a 1 minute resolution so please do not degrade the resolution of your data set just to make is smaller. If it does not fit into the following anonymous ftp site then send me an e-mail and I'll find another place for it.
