The Caulerpa Challenge
Let the facts be a part of the solution
When Tairua local Will Fransen fell off his boat in January while fishing beyond the Aldermen Islands, he drifted over 55 km in the currents in little over 24 hours. Incredibly, he was found alive.
If the currents and tides can carry a human this far, imagine the distance a small fragment of invasive seaweed like Caulerpa can spread on the same currents. Particularly because the tides and currents flow day in and day out.
