Largest coastal mapping survey

Date: 3/2/2009

The survey covers more than 3500 square kilometres of New Zealand’s Northland’s seabed and has revealed reefs, new information about the iconic Hole in the Rock and mapped a prominent wreck site. Three National Institute of Water and Atmospheric Research (NIWA) vessels mapped the Bay of Islands and eastern Northland coast seabed late in 2008 as part of the government’s Ocean Survey 20/20 programme. Most of the area from two to 50 metres was mapped using multi-beam and sidescan sonar.
