In the spring of 1992 an optical closure experiment was conducted at Lake
Pend Oreille, Idaho. A primary objective of the experiment was to compare techniques
for the measurement of the spectral absorption coefficient and other inherent optical
properties of natural waters. Daily averages of absorption coefficients measured using
six...
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...
Infrared radiometers, photographs, and a multispectral
scanner were used in a remote sensing study of the ocean off
Oregon during the summer of 1969. Upwelling appeared on
infrared temperature maps as a zone of cold water along the
coast and Columbia River water appeared as a warm water
"plume". Sharp...
