Paper Abstract

Radiance and irradiance measurements are collected using a seven channel profiling radiometer and a four channel moored irradiance sensor which both use Sea-viewing Wide Field-of- View Sensor (SeaWiFS) wavebands. The instruments were deployed as part of the Land-Ocean Interaction Study, shelf edge study on the Malin Shelf, off the west coast of Scotland, during spring and simmer 1995 and 1996. Changes in in-situ reflectance ratios, calculated from the blue, cyan and green wavebands of the moored color sensors, suggest a diatom-dominated spring bloom, followed by an early summer coccolithophore bloom, with a flagellate-dominated phytoplankton population during the summer. Similar changes are also seen in attenuance ratios and specific attenuation coefficients calculated from the profiling radiometer data. The use of these optical properties to determine phytoplankton floristic composition is discussed.
