Banks Peninsula, New Zealand: A line perpendicular to the coast south of Banks Peninsula, New Zealand. This very visible line is probably caused by a wind associated with a weather system changing the surface reflectance for this sun angle. At the north edge of the plankton bloom is the subtropical convergence zone where subtropical (productive) waters from the north meet sub-Antarctic (much less productive) waters from the south. The two currents meet and flow outwards from the shore in an eastward direction over the Chatham Rise, where water depths decrease from 2,500 m to 125 m over a relatively short distance. This bathy- metrically locked feature is seen in many images (including AVHRR) and marks an area of very productive water, high in phytoplankton. Communique to S. Runco from Richard Murphy, National Institute of Water and Atmospheric Research, Wellington, New Zealand.
