Bio-optical sensors would supplement satellite observations of the ocean's color by providing measurements of chlorophyll, light, and light scattering deep into the ocean interior throughout the year, in cloud - and ice - covered areas, or during the dark of polar winter.
Just in case someone was tempted to accuse me of «hanging my hat» on (sea surface) measurements of Chlorophyll a alone.
The phytoplankton analysis, by Daniel G. Boyce, Marlon R. Lewis and Boris Worm at Dalhousie University, drew on a variety of types of data, from thousands of water transparency readings taken since the end of the 19th century by lowering a white disk into the sea to direct and satellite measurements of chlorophyll.

«Satellites map photosynthesis at high resolution: Precise measurement of the solar - induced chlorophyll fluorescence enables scientists to quantify gross primary production.»
«Precise measurement of the solar - induced chlorophyll fluorescence, derived from OCO - 2 — but also from follow - on missions such as the European Sentinel - 5P, which will be launched coincidentally now on October 13th — enables scientists to quantify gross primary production and its contribution to the global carbon cycle,» says Guanter.
For example, previous global initiatives include satellite - based chlorophyll measurements, the Census of Marine Life, long - term observation sites, and arrays of remote sensors on floats that provide physical, chemical, and biological data [15].
The researchers compared GOSAT short - wave infrared Fourier transform spectrometer data collected between 2009 and 2013 with water level data from Gravity Recovery and Climate Experiment observations to approximate drought and used satellite measurements of solar - induced chlorophyll fluorescence as a proxy for vegetation levels.
Satellite pictures of chlorophyll (cell pigment that converts sunlight into energy) give a general idea of the amount of phytoplankton present, and oceanographers hope that future satellite measurements will further clarify the picture.
These sensors would provide real - time data for pH, oxygen, nitrate, chlorophyll, suspended particles, and measurements of the amount of the penetrating sunlight (downwelling irradiance) that drives photosynthesis.
