As part of an ongoing project to understand sand movement in and around Whangamata, eCoast were asked to deploy multiple oceanographic instruments and collect bathymetric data over the course of a month.  To collect bathymetric data, eCoasts survey vessel, ‘Red Rocket’ was used.  The jet ski is fitted with a through-hull transducer and RTK GPS.  The jet ski was chosen over our larger survey and dive platform because of the skis unmatched manoeuvrability, stability and reliability in the surf zone, and capacity to access extremely shallow areas.
