The Wadden Sea is a highly dynamic tidal system and an important area for a variety of species, including wild and cultivated mussels. Increased suspended sediment concentrations may negatively affect ecosystem functioning across trophic levels; hence, insight into the effects of anthropogenic activities is of importance. The aim of this study was...
The frequency of heatwave events in Europe is increasing as a result of climate change. This can have implications for the water quality and ecological functioning of aquatic systems. We deployed three spectroradiometer WISPstations at three sites in Europe (Italy, Estonia, and Lithuania/Russia) to measure chlorophyll-a at high frequency. A heatwav...

Executive summary and recommendations The EU Water Framework Directive 1 (WFD) is an ambitious legislation framework to achieve good ecological and chemical status for all surface waters and good quantitative and chemical status for groundwater by 2027. A total of 111,062 surface waterbodies are presently reported on under the Directive, 46% of whi...
Introduzione Il monitoraggio della qualità dell'acqua nei laghi è di fondamentale importanza per la comprensione delle dinamiche ecologiche e per la loro gestione. In aggiunta ai parametri fisici e chimici delle acque e dei sedimenti, la conoscenza delle caratteristiche e quantità della componente biologica è di fondamentale importanza. Negli ecosi...
The complex aquatic ecosystems, such as lakes, are characterized by a high level of hourly and daily dynamic due to the rapid growth / decrease of phytoplankton, and to the variation of the suspended solids due, for examples, to the wind-induced re-suspension of the bottom sediments. This variability is then changing depending on locations, so that...

A new autonomous above water radiometer system (WISPstation) was developed based on the experience with the handheld WISP-3 system. The instrument records radiance and irradiance with an extended wavelength range of 350 to 1100 nm in two viewing directions, which enables continuous and autonomous high-quality measurements for water quality monitori...

Shallow and deep lakes receive and recycle organic and inorganic substances from within
the confines of these lakes, their watershed and beyond. Hence, a large range in absorption and
scattering and extreme differences in optical variability can be found between and within global
lakes. This poses a challenge for atmospheric correction and bio-opti...
The scope of this document is to show how satellite data, especially GLaSS products, can be used to detect mine tailing ponds in Azerbaijan, Finland and Mongolia.
The GLaSS training material (10 lesson) builds on the global lakes use cases of FP7 project GLaSS. It allows students (((Bsc), Msc, PhD) and professionals in fields as aquatic ecology, environmental technology, remote sensing and GIS to learn about the possibilities of optical remote sensing of water quality, by using the Sentinel-2 and Sentinel-3...
The objective of this document is to analyse the usability of GLaSS products for the monitoring and reporting required for the Water Framework Directive. The document starts with an introduction to the directive. The directive monitoring and reporting activities of six member states (Finland, Estonia, Sweden, Germany, The Netherlands and Italy) are...
The scope of this document is to report on the investigations and analysis performed and conclusions related to the above stated objectives. The analysis was focused on comparison of water quality estimations from the two HYPE models, S-HYPE andE-HYPE, and MERIS based water quality estimations in several European lakes. The objective was to illustr...
Boreal lakes often contain high concentrations of colored dissolved organic matter (CDOM). This leads to strong absorption of light especially in the blue and green parts of the spectrum and complicates the use of EO methods. Standard algorithms often fail in these waters and new methods are needed. This document describes the results of five studi...
To demonstrate the applicability of the system developed in the project and to assess changing of the trophic status impacting water uses, EO data were used for selected deep waters. EO data provides in fact a synoptic vision and a good sampling frequency suitable for the evaluation not only of the trophic state but also of changes in trophic state...
This use case studies turbid shallow lakes. There can be several factors affecting the turbidity: for instance, wind waves causing re-suspension can cause a high turbidity, but also glacier melting adds loads of fine particles to glacier lakes. Within the socio-economic analysis of GLaSS (GLaSS D5.1) it was found that many lakes that present high t...
The European collaborative project GLaSS aims to prepare for the use of the data streams from Sentinel 2 and Sentinel 3. Its focus is on inland waters, since these are considered to be sentinels for land-use- and climate change and need to be monitored closely. One of the objectives of the project is to compare existing water quality algorithms and...
The North-Western part of the Black Sea is highly affected by eutrophication due to nutrient and sediment load inflow from the Danube River, which is the second largest delta in Europe. To get a general spatial picture of the water quality of the Romanian coast, it is not only time consuming, but also hard to measure with traditional in situ sampli...
The scope of this document is to report on the developments, functionality and technical details of a tool for extraction of valid lake pixels for time series production. The developments are based on existing elements already implemented in BEAM, which provides functionality for definition of valid pixels based on external or predefined masks and...

Multispectral information from satellite borne ocean colour sensors is at present used to characterize natural waters via the retrieval of concentrations of the three dominant optical constituents; pigments of phytoplankton, non-algal particles and coloured dissolved organic matter. A limitation of this approach is that accurate retrieval of these...
Optical close-range instruments can be applied to derive water quality parameters for
monitoring purposes and for validation of optical satellite data. In situ radiometers are often
difficult to deploy, especially from a small boat or a remote location. The water insight spectrometer
(WISP-3) is a new hand-held radiometer for monitoring water quali...

Ocean colour-based monitoring of water masses is a promising alternative to monitoring concentrations in heterogeneous coastal
seas. Fuzzy methods, such as spectral unmixing, are especially well suited for recognition of water masses from their remote
sensing reflectances. However, such models have not yet been applied for water classification and...
In this study, the inverse bio-optical model HYDROPT was calibrated with regional specific inherent optical properties (SIOPs) and various local SIOPs to examine the effect of these calibrations on the retrievals. The study area, the Wadden Sea, is an estuary and tidal flat area with very high concentrations of chlorophyll a (Chl a), suspended part...
The interpretation of optical remote sensing data of estuaries and tidal flat areas is hampered by optical complexity and
often extreme turbidity. Extremely high concentrations of suspended matter, chlorophyll and dissolved organic matter, local
differences, seasonal and tidal variations and resuspension are important factors influencing the optica...
With its 500 km length the Wadden Sea is the largest mudflat area in the world. Discharges from various rivers mix here with water from the North Sea. Due to surfacing tidal flats during low tide, the variation in source water, resuspension and extremely high concentrations of Chlorophyll-a (Chl-a), Suspended Particulate Matter (SPM), and Coloured...
The Wadden Sea, a shallow coastal area bordering the North Sea, is optically a complex area due to its shallowness, high turbidity and fast changes in concentrations of optically active substances. This study gathers information from the area on concentrations of suspended particulate matter (SPM), Chlorophyll-a (Chl-a), and Coloured Dissolved Orga...
The Wadden Sea is a shallow coastal sea, interesting because it is a Particular Sensitive Sea Area. It is also optically an interesting area because of mudflats, tidal inlets from the North Sea, discharges from various rivers, great variation in time and space of optically active substances, very high concentrations of optically active substances....
