Initial low-resolution field map of multibeam backscatter in the large embayment just north of Coromandel Harbour. Light grey indicates harder seafloor substrates; the rectangular features are mussel farms, with both the farm structures and the seafloor below contributing to the backscatter return. High juvenile snapper (< 90 mm) densities occur in this area; it contributes a significant part of one of four key Hauraki Gulf snapper nurseries.
