Nasiha Jahirhussain
Post Doctoral Researcher
Nasiha is an optical oceanographer, carrying out research in satellite remote sensing analysis of coastal, estuarine and open ocean waters. Earlier research modules during her Ph.D. work were involved in biogeochemical characteristics of oceanic waters by the use of remotely sensed satellite imagery. Nasiha had developed several in situ observation-based ocean optical models and their proof-of-concept algorithms for remote sensing implications, to better understand the oceanographic particle system spanning from sediment settling velocity to particulate load composition. Nasiha engaged in a number of ocean research cruises for the field measurement of optical-oceanographic parameters such as radiometric quantities, coefficients of absorption, attenuation, scattering and fluorescence, turbidity together with aerosol optical thickness of the atmospheric column.
Presently, Nasiha is working in the FOCOS (Ferry Ocean Colour Observation Systems) research project that acquires and utilizes autonomous above-water radiometric measurements, primarily for the satellite remote sensing applications of marginal seas and dynamic coastal waters. Her recent study depicted the spatial variability of in situ remote sensing reflectance to derive uncertainties associated with transitional water boundaries and optically complex coastal waters. The research work showed that the high spatial variability in remote sensing reflectance was predominantly associated with the spatial dynamics of the optical water constituents, thus limiting the use of these datasets as Fiducial Reference Measurements for the satellite validation process. Nasiha is currently working with a large hyperspectral FOCOS dataset for the robust evaluation of satellite retrieved and atmospherically corrected reflectance.
Nasiha is an independent researcher, yet a collaborative teammate. To further say about Nasiha, she believes in the collective knowledge acquired by humanity to date, and her favorite quote is by Isaac Newton, “If I have seen further it is by standing on the shoulders of Giants”.
