The Moana TD sensor and Deck Unit have been developed as a key part of the Moana project (see below). The system has now been successfully rolled out to over 250 commercial fishing vessels around New Zealand, on boats ranging in size from small in shore day boats to deep water factory trawlers.
The Moana TD sensor is a tough robust accurate sensor that can be quickly and easily attached to a wide range of commercial fishing gear. Once fitted, the sensor operates automatically, recording high accuracy temperature and depth data throughout the fishing event. When the fishing gear surfaces, the data is automatically offloaded to the Deck Unit that is mounted on the vessel
The Deck Unit processes the data and then uploads it to the cloud. The system is fully automatic and so does not interfere with the fishing operation.
The Moana project is a multi-organisation New Zealand project that was established in 2018 with the objective of improving our understanding of the New Zealand coastal and ocean circulation, connectivity and marine heatwaves, and to provide information that supports sustainable growth of the seafood industry.
As part of the project, ZebraTech developed the Moana TD (named Mangōpare within the Moana project) and Deck Unit that has now been installed on over 250 fishing vessels around New Zealand. These vessels range from small inshore day boats to deep water offshore factory ships.
Every day many thousands of high resolution position based sub-surface water temperature measurements from all around New Zealand are automatically reported into the MetOcean database. The data is then used by both scientists and fisheries for a wide range of vital purposes, such as improved weather forecasting, marine heatwave modelling, optimizing fishing activities and climate change monitoring.
In addition to New Zealand, Moana systems are now in use around the world, including Greenland, Louisiana, Maine, France, Holland, Mexico, Australia, Indian Ocean and the Southern Ocean.
