Optical sensors installed on ships, for instance, can determine
ocean water
color that reflects the activity of micro-algae at the bottom of the food chain and, when examined alongside
satellite color observations, can support extrapolations about what's happening in a given area of
ocean.
Orbiting instruments like the Moderate Resolution Imaging Spectrometer on the Aqua
satellite, and the Visible Infrared Imaging Radiometer Suite on the Suomi NPP
satellite collect data on the

color, we were able to develop techniques to calculate how much of the biomass occurs in very large or very small particles.»
This is an important finding because current estimates of biological activity in surface waters of the
ocean rely on instruments aboard
satellites that measure the
color of the sea surface, which changes along with levels of chlorophyll - a, an assessment that will miss blooms of other organisms, such as bacteria.
Many NASA
satellites observe environmental factors that are associated with El Niño evolution and its impacts, including sea surface temperature, sea surface height, surface currents, atmospheric winds and

colors of the
ocean to gauge the global flow of algae and the influence of
ocean aerosols on cloud formation.
NOAA Coastwatch Coastwatch is a NOAA resource that provides a variety of remotely sensed data from several different
satellite platforms covering U.S. coastal waters, including sea surface temperature,
ocean color, and winds.
So, while the Boyce et al paper is certainly provocative, I would wait another several years to see what the long - term trends in chlorophyll are from
satellite retrievals of
ocean color.
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.
The combination of a series of Earth - observing
satellite sensors, including the most recent Visible Infrared Imaging Radiometer Suite (VIIRS) and Sentinel - 3, could enable the production of a near - daily record of global
ocean color measurements now spanning nearly 2 decades.
Ocean -
color - sensing
satellites measuring productivity are the primary source of phytoplankton information.
Summertime
satellite observations of
ocean color from MODIS / Aqua show highly turbid waters which may include large blooms of phytoplankton extending from the mouth of the Mississippi River all the way to the Texas coast.
