New horizons for hydrography

Compared to the complexity required measure other physical quantities, continuous monitoring globally of water levels, current directions, and velocities, as well measurement underwater topography, do not appear ambitious tasks for modern technologies. The challenges lie in sheer size area be measured, which makes up about 70% Earth’s total surface, its constant variability due natural processes, inaccessibility seabed, still inadequate mathematical modelling global geophysical processes at oceanic scale. Since most world’s population lives on, from with oceans, a demand-oriented provision hydrographic information is fundamental importance. Hydrography called upon serve this need support informed decision-making.
