This was mounted vertically in the centre of a protective cage approximately 1.5m square. Attached to the bars of the frame were a Chelsea Instruments Aquatracka fluorometer, and a SeaTech red light (661nm) transmissometer with a 25cm path length. Note that the fluorometer was changed during the cruise as detailed in the calibration section below. Above the frame was a General Oceanics rosette sampler fitted with 12, 10 litre water bottles. Initially, 10-litre Go-Flo bottles were used but problems with leakage (confirmed by measuring the temperature of the water samples) were encountered, even at relatively shallow depths. Consequently, Niskin bottles carried as spares were subsequently used for as much of the sampling work as possible. Where leakage has been reported, th
