In this webinar, Heni Unwin and Ross Vennell from the Cawthron Institute will showcase an interactive online tool they’ve developed to predict the movement of plastic waste around New Zealand’s coastline.

Register to join

The Ocean Plastic Simulator uses regional models of tides, winds and currents to track how plastic moves and where it will end up. You can drop virtual plastic at four locations: Cook Strait, Golden and Tasman Bays (Te Tau Ihu), Hauraki Gulf/Firth of Thames and Tauranga Moana. The model is based on a plastic water bottle floating in the top 3 metres of the sea.

Plastic waste is a global problem and is destroying marine environments. Plastic that ends up in the ocean can accumulate on beaches or be transported many kilometres by ocean currents. The tool shows how coastal communities are connected.

Potential uses of the simulator

Initially designed as an educational tool for schools, the simulator also has potential for environmental monitoring. With the right source data, it can easily be modified to show where plastic pollution has come from or to predict movement of living things. For example, the aquaculture industry could use it to predict or track movement of larvae and spat, invasive species, or lost equipment.

This webinar is open to everyone but will be of particular interest to regional councils, marine managers, researchers and the aquaculture industry.  

You can join us at the venue, through a virtual hub, or register via Zoom videoconferencing to view on your own device.

We welcome questions in advance if you have anything specific you would like covered.
