New Zealand’s First Combined Hydrographic and Marine Science Survey

New Zealand’s First Combined Hydrographic and Marine Science Survey

Land Information New Zealand and Marlborough District Council contracted NIWA and DML to undertake the first combined hydrographic and marine science survey of all of Queen Charlotte Sound.

Bruce Wallen, one of New Zealands most highly experienced hydrographic surveyors, has just completed nearly 8 months in the field with a multidisciplinary team of hydrographic surveyors and marine scientists. The survey was particularly challenging due of the complexity of the marine environment ranging from sheltered waters at Picton through to the open sea at the Brothers Islands in Cook Straight. The Kaikoura earthquake, with a magnitude of 7.8 (Mw) just after midnight on 14 November, added to Bruce’s challenges.

With the fieldwork now complete the next phase begins. Bruce, along with a dedicated team of data processors now commence the challenging task of processing the terabytes of multibeam survey data in preparation for the scientists to process the backscatter as part of the marine habitat mapping. The final results of all the hard work are due late in 2018.
