In situ attenuation (488 and 660 nm), absorption (488, 676, and 750 nm), backscattering (at 488 nm), and
stimulated fluorescence were determined as functions of depth in oceanic and coastal waters off Oregon,
using both commercial instruments and recently developed prototypes. The inability to perfectly constrain
scattered light in these...
Theoretical scattering computations are performed on a phytoplankton model consisting of three
concentric spheres. The outer sphere represents the wall, membrane, or frustule and is assigned a
relatively high index of refraction with no absorption. The middle layer represents the chloroplasts
and is assigned a relatively low index of refraction...
A method for predicting oceanic productivity from remotely sensed diffuse attenuation (488 nm) and
surface chlorophyll concentration is presented. The method uses a climatological approach which consists
of applying a set of regressions for each region and season to yield the depth of the chlorophyll maximum,
the exponential slope of...
