Citizen science with Jessie Mulligan on RNZ Afternoons

Opua in the Bay Of Islands is currently host to a flotilla of 25 boats. They're waiting for the right weather conditions before hoisting anchor and setting sail on 2024 Pacific Rally, which is a six month voyage across the ocean.

This year the sailors have also been recruited for a huge science experiment. James Frankham, publisher at New Zealand Geographic and co-founder of Citizens Of The Sea—the charity behind the effort—speaks to Jesse Mulligan on Afternoons.
