Optical remote sensing of water quality in the wadden sea
The thesis presents how remote sensing techniques and observations can be employed to accurately tetrieve water quality variables in complex coastal waters at both the water surface and top Of Atmosphere (TOA) levels in the frame of proposing and evaluating the lates remote sensing methods and techniques established based on radiative transfer modelling, advanced retrieval methods, developed algorithms and optimal instruments and sensor. Tis dissertation is composed of six dhapter 1 is introductory and describes the optical remote sensing of water quality, the chanllenges and requirements to apply the remote sensing techniques in the coastal waters, the importance of the study area and the proposed methods and algorithms in this study. CHapter 2 deals with application and validation of a new and developed readiative transfer hydro-optical model to accurately ttetrieving water quality variables at water surface level under various solar zenith angels and water turbidity conditions by using insitu hyperspectral measurements. Chapter 3 deal with applications and validation of a proposed radiative transfer atmospheric-hydro-optical model to simultanteneously terieve water quality variables and atmospheric properties at TOA level by usingMEdium Resolution Imaging Sepctrometer (MERIS) images. Chapter 4 deals with 15-years water quality monitoring in complex coastal water of the Dutch Wadden Sea by using time series of diurnal in-situ hyperspectral measuremesnts and multi sensor satellite images of MERIS, sentinel-2 MUltispectral Instrument (MSI) and sentinel-3 Ocean and land colour Instrument (OLCI) images. CHapter 5 deals with the problem of the sea-bottom effect in the shallow coastal waters and develops a refined hydro-optical model on remote sensing observations in these area. Future analysis and investigations in this chapter lead to proposing a new near-infrared bottom effectc index to distinguish optically shallow water from optically deep waters. Chapter 6 discusses the main objective of this dissertation and explains how these objectives are achieved and provide research recommendations for future studies.
