ALT Figure of instruments used on-board the RRS James Clark Ross. The ship is shown with 4 panels pointing to different parts. The panels are (A) Secchi disk attached to the optics rig with 2 Forel-Ule colour scales (B) CTD Niskin Rossette used to collect water samples of Chl-a, measure PAR and beam attenuation (C) HyperSAS radiometer set-up (photos from AMT23) with the 2 radiance sensors positioned on the very bow of the ship and the downwelling irradiance sensor positioned vertically on the met-platform on the ship’s foremast (D) Photos of water colour collected on AMT23 in (1) centre of the South Atlantic gyre, (2) edge of the North Atlantic gyre, and (3) South Subtropical Convergence Zone, illustrating visual transitions from blue to blue-green waters.
