NIWA’s second-largest research vessel is the RV Kaharoa. She is less than half the size of the RV Tangaroa (only 28 m in length) but has made some awesome voyages!
The RV Kaharoa has deployed more Argo Floats than any other vessel sailing over 76 996 nautical miles as far afield as Chile, California, and Mauritius.

The RV Kaharoa has an award for being a "World Champion Argo Float Deployer". Most Argo Floats get deployed off the side of regular container ships but the RV Kaharoa goes places away from regular shipping routes- she's one gutsy gal! There are over 3500 Argo Floats in the ocean. The RV Kaharoa has deployed over 1300 of them!

Map showing locations of Argo Floats deployed by the RV Kaharoa. (All except those at latitudes south of 45S which were deployed by another NIWA research vessel, the RV Tangaroa)

11 October 2012- managed to load 98 Floats into a container ready for deploying on th Kaharoa's latest voyage- the other floats will be in the ship's hold. From left: Basil Stanton (former physical oceanographer at NIWA, now olive rancher in Blenheim), Rick Rupan (University of Washington) (in the container) Phil Sutton (Physical oceanographer at NIWA), Alan Poole (CSIRO tech), Michael McClune (Float engineer, Scripps Institution of Oceanography) (in container), Dean Roemmich (SIO Physical Oceanographer, co-chair Argo Steering team)
Niwa's John Hunt will be heading to Chile and deploying half of the 120 floats- he knows that he may be heading into some 10m swells on this trip! Kia Kaha John!
