Resumen:
The limits
of optical remote sensing of aquatic systems are being progressively
pushed into more and more turbid water, because of growing interest in
the environmental impacts of the worlds most important river
estuaries/plumes and in the monitoring of inland waters. This evolution
has already led to refinement of the black pixel assumption for the near
infrared (NIR: 700-1000nm) marine reflectance and to the development of
NIR-based Total Suspended Matter (TSM) retrieval algorithms for
moderately turbid waters (10-100 g/m3). Extension of such approaches to
extremely turbid waters (TSM> 100 g/m3) requires further refinement
of theory and atmospheric correction algorithms. Use of the Short Wave
Infrared (SWIR, 1-3 mm) range then offers new opportunities, but
requires fundamental research and measurements for a sound theoretical
basis.
