Optical remote sensing of aquatic ecosystems: crossing boundaries from turbid coastal waters to the blue open ocean
Nagur Cherukuru (CSIRO)
Optical remote sensing instruments measure the light backscattered from water and across the air-sea interface. These measurements are made using in situ instruments or space-borne sensors. Water-leaving radiance is influenced by inherent optical properties (such as backscattering and absorption) of particulate and dissolved substances in water. Inherent optical properties of these substances are dependent on their biogeochemical nature. Detailed understanding of the bio-optical relationships, inherent and apparent optical properties will help interpret the remote sensing signal both in complex coastal waters and in clear open oceans. Information thus derived from optical remote sensing data plays an important role in improving our monitoring and management practices. Significant advances have been made in recent years in in situ and space-borne optical sensor design, measurements and development of inversion algorithms. These developments have facilitated the availability of biogeochemical and optical products with high spatial and temporal resolution. To provide a forum to assess these recent advances in optical remote sensing we invite contributions from studies that focus on in situ optical measurements, inherent and apparent optical properties, time-series bio-optical measurements, forward and inverse bio-optical modelling, optical remote sensing derived products such as inherent optical properties, concentrations of particulate and dissolved substances, phytoplankton functional types, primary production estimates, particle size distribution and bathymetry and optical data assimilation into ecosystem models.
