If you are the author please contact PEARL Admin ([email protected]) to discuss options.Remote sensing is an efficient tool to monitor the aquatic ecology. The optical
signature in coastal marine environment is a reflection of the complex distribution of
optically active marine components. It is essential to understand the relationship
between the remote sensing signal and marine constituent material to take advantage
of high resolution remote sensing data available from spaceborne and airborne
platforms. The objective of this research was to develop a semi-analytical forward
model to predict the remote sensing optical signature in coastal waters dominated by
non-planktonic material. Laboratory and in situ measurements collected over a5 year
period (1998-2003) were used to compile a biogeooptical database for coastal waters.
The database is exploited to realise various biogeophysical relationships. A major
advancement proposed in the thesis towards the modelling of backscattering
probability was the synthesis of knowledge from Mie theory and particulate
composition from geochemical analysis. This approach was used to derive particulate
backscattering from in situ absorption and attenuation measurements. Results show
that this model can produce backscattering values in a realistic way than with a
constant value as proposed by Petzold. Absorption and backscattering values derived
from ac-9 measurements were used to calculate radiance reflectance and remote
sensing reflectance. The biogeophysical relationships developed were incorporated
into the forward optics model to successfully simulate the inherent optical property
ratio. Further development of the model and applications through inversion were
discussed and outlined.Plymouth Marine Laborator
