CIMA members are executing in collaboration with OCPortugal partners a set of investigations supporting the validation of MEdium Resolution Imaging Spectrometer (MERIS) data products in selected European coastal basins.
The first part of the study addressed the selection and quality assurance of field measurements for deriving seawater inherent optical properties from reflectance data in optically complex coastal basins.
Reference field measurements were produced within the framework of the Bio-Optical Mapping of Marine Properties (BiOMaP) led by the Joint Research Centre (JRC), Ispra, Italy. During the second part of the study, operational MLP neural networks were implemented to derive Chlorophyll-a concentration, absorption of the yellow substance at 412 nm and concentration of the total suspended matter (Chl-a, ays(412) and TSM, respectively) from normalized remote sensing reflectance (RRS) on the basis of BiOMaP data. Specific investigations were executed for the Adriatic Sea, the Baltic Sea and the Black Sea.
Current work progresses focus on the extension of this the analysis to Oceanic water off Portugal. Results have shown that it is possible to derive accurate products in optically complex sea waters through specific regional algorithms.

The REmote Sensing Monitoring of the Atlantic off Portugal RESMAP project (Jan, 2014–Dec, 2018) is funded by the Fundacão para a Cîencia e a Tecnologia (MCTES, PT; Ref. no.: PTDC 2018 IF/00541/2013; exploratory project).
The Centro de Oceanografia (CO) is a multidisciplinary research unit of the national R&D system, whose main host institution is the Faculty of Sciences of the University of Lisbon (FCUL), the other host institution of this Centre being the University of Évora (UE).
The main research lines of the Centro de Oceanografia are the following:
Faculdade de Ciências e Tecnologia (Faculty of Science and Technology; FCT) is one of the nine academic units of Universidade Nova de Lisboa (UNL). The FCT/UNL campus is located in Monte de Caparica and covers approximately 30 ha, with additional capacity expansion to 60 ha. Founded in 1977, FCT/UNL is one of the most prestigious Portuguese public schools of science and engineering today, with a total enrolment of ca. 7500 students, of which nearly 1400 are postgraduate students (MSc and PhD).
