Bay of Islands to Tonga
Leg 2
This is an exciting and challenging ocean crossing from New Zealand to Tonga focusing on science at sea by sampling for mircoplastics offshore.
We begin with land-based scientific work around the Bay of Islands before setting sail. We will conduct continuous water sampling offshore and across the mid-ocean. Our route takes us along the Tongan Trench, a biodiverse area known for its deep-sea life and whale migratory route.
Weather permitting, we plan to stop at the entirely unique Minerva Reef. This volcanic tip in the middle of the ocean offers a stunning and abundant underwater world. We will explore this special location by snorkeling and paddleboarding.
The voyage concludes in Nuku’alofa, the capital of Tonga, where we will carry out further land-based science and connect with local partner organisations.
We will be waiting for the best weather window to depart New Zealand, so applicants for this trip must be prepared for flexibility in the itinerary.
