Ocean Globe examines bathymetry as it is practised and used within the the world's oceans. The data gathered, produced and used often relies upon geographic information systems (GIS) and other technologies. Seafloor mapping and bathymetry are discussed through both historical and current work as presented by historians, oceanographers and explorers of the ocean. Topics include animal migrations, aquatic farming, tsunami, whale habitats and the evolution of modern bathymetry mapping technologies such as lidar, echo sounding and radar techniques. The delivery of this information is outlined for server-based GIS use.
