Roadmap for Future Ocean Floor Mapping

• by brian wang

Mapping through ocean water deeper than a few meters excludes the efficient use of electromagnetic waves such as radar and light, which forms the basis for methods used during terrestrial and extra-terrestrial mapping missions. While ocean surface height measured by satellites can be used to derive a coarse view of the ocean floor, it does not have sufficient resolution or accuracy for most marine or maritime activities, be it scientific research, navigation, exploration, shipping, resource extraction, fisheries or tourism. Traditional bathymetric mapping techniques rely on acoustic mapping technologies deployed from surface or submerged vessels and require broad international coordination and collaboration towards data assimilation and synthesis.

Mapping the entire World Ocean floor is an ambitious effort, specifically considering that 50% is deeper than 3200 m and large parts
at high latitudes are permanently covered by sea ice.
