What are the impacts of water dams on water quality and mahinga kai?

Hull-mounted on the RV Tangaroa, the EM302 multibeam echosounder maps the seafloor using a fan of 288 acoustic beams, producing up to 864 soundings per ping in dual swath mode, providing 100% coverage of the seabed.

The current method for calculating wind speed-up is inadequate, and can grossly under-predict correct design wind speeds in NZ's complex terrain.
