Annual GEBCO Symposium

The GEBCO Symposium, formerly Science Day, is held every year as part of GEBCO's meetings. It consists of oral presentations and poster displays on topics relating to ocean-floor mapping and its applications. Access presentations and posters from The GEBCO Symposium.

Forum for Future Ocean Floor Mapping

The Forum was held in June 2016 and brought together over 150 senior representatives, scientists and scholars from major ocean-related and international organisations to discuss the importance of understanding the shape of the ocean floor. It will culminate in the development of a Roadmap for Future Ocean Floor Mapping.

GEBCO Data Flow Workshop (2011)

The workshop was held at the US National Geophysical Data Center (now the National Centers for Environmental Information (NCEI)), 9-11 March 2011. The aim of the workshop was to develop a plan to allow data to flow in a predefined manner though the GEBCO community and be incorporated into GEBCO's global bathymetric grid.

GEBCO Centenary Conference

The conference was held in Monaco in April 2003 to mark the 100th anniversary of the initiation of the GEBCO chart series.

Presentations were given on a wide range of topics from the early years of GEBCO; the development of bathymetric mapping through the 20th Century and beyond and the applications and implications of bathymetry data.
