I specialize in optics, radiative transfer, and remote sensing in order to ascertain
various ocean properties: pigments, detritus, dissolved organic matter, shallow
bathymetry, and sea grass coverage. Since as much as 90% of the visible signal collected
from space is derived from the atmosphere even on relatively clear days, mathematical
removal of the atmospheric effects of molecular and aerosol scatter and absorption is
required in order to observe the ocean. Then, in order to assess the bottom components in
shallow waters, another 80% or so of water scattering and absorption effects must be
removed. To assist with model development and validation, the optical properties of the
ocean and bottom are also measured. A temporal and thematic range of papers are listed
below from determining particle properties and dynamics to deriving atmospheric, ocean,
and bottom properties from aircraft and space. Applications to red-tide, global
carbon-cycle, and heat-budget research are inherent in the themes of these papers.
