SIMON O'CONNOR/Stuff The sub-sea survey team of data scientist Eva Lichtenburg Cloo, left, Discovery Marine Ltd lead hydrographer Jimmy van der Pauw and Land Information NZ senior hydrographer Bradley Cooper. “What we are looking for is any rocks or structures that have not been charted before, that may pose a hazard to surface navigation,” van der Pauw said. Up to 300Gb of data can be recorded during a typical 6-8 hour sounding day, van der Pauw said. Once the survey is completed the digital charts and data will be available on the LINZ data service online.
