This CTD frame houses a rosette of large, grey Niskin bottles and is ready for deployment in the MARGINS Waipaoa New Zealand focus site. As the frame is lowered through the water column, the bottles are triggered to open and close at specific depths to allow the collection of water samples. Digital instruments on the frame also collect temperature and conductivity data. Image courtesy of JP Walsh, ECU.
