Objectives of the research & technology development programme of WaterS

1) Development of ground-based techniques for the observation of optically complex waters - Improve interpretation of optical signals from remote sensing platforms for the optically complex Nordic waters (lakes and near-costal Baltic and eastern North Sea) through bio-optical modeling of characterized variability in optical properties. - Innovation in development of spectral instruments to perform state-of-the-art measurements optimized for optically complex and heterogeneous aquatic environments, starting from the measurement signals and pursued up until the level of processing and disseminating the information for public release.

2) Remote Sensing Techniques - Increase the operational monitoring capability of EO data by specifying, testing and developing processing algorithms which take account characterization of local aerosol properties and climatology over the Nordic region; bottom vegetation types and other environmental effects for optically complex waters, using the database collected during the project and the expertise of the research partners.

3) Ecological Mapping through optical signatures - Improve the understanding of optically complex waters by means of classification and typification for mapping optical water types. Generate better knowledge about ecological status of lakes in Nordic region. - Development of novel product for lakes water quality assessment and mapping, as a precursor for a potential operational services using EO capacities, water quality retrieval algorithms and GIS systems for Ecological assessment of Lake Water Quality parameters.

4) Data Management and Processing - Incorporate the developed technology into commonly used remote sensing tools published as open source code, to assist implementation and operations of operational remote sensing services in the region and ERA.

Due to the global change and the strong human impact on natural water resources it is crucial to improve regular aquatic monitoring methods. The EC Water Framework Directive requires the assessment of the ecological status of European waters. The satellite technique provides a synoptic view of whole water bodies and has shown to be a very cost-effective method to monitor changes in aquatic ecosystems. Monitoring harmful algal blooms is particularly important for marine aquaculture and fisheries, as well as for tourism. In northern latitudes the winter season introduces particular problems with ice formation and melting. Human activities are different than in ice free conditions and safe traveling on ice is a critical question. The purpose of the NordAquaRemS is to aggregate efforts in solving common scientific and user-oriented problems, to share resources, training and expertise, and increase staff and student mobility. In summary, the proposed network will aim for:

recruitment of well-qualified PhD students into the field
organizing annual PhD/research training courses
sharing of scientific expertise, facilities and human resources
improvement of the atmospheric correction over optically complex Nordic waters
improvement of data sharing
improved exchange between scientists, users and service providers.

With increasing requirements for the European Commission Water Framework Directive, monitoring of coastal areas is in the focus of research as well as related industries. Remote sensing is of special interest, as large areas can be sampled at once, beyond country borders and even automatically.

The Baltic Sea is one of the most polluted areas in the world and is especially vulnerable to environmental changes caused by climate change. Issues that are particularly important in the Baltic Sea are monitoring of harmful algal blooms, which is important for marine aquaculture, fisheries and tourism, and monitoring of snow and ice, necessary for safe travelling on ice. Remote sensing of the Baltic Sea is a challenge, as it is very heterogenic, contains large amounts of humic substances and often has a low solar angle. However, it has been shown that with dedicated and locally calibrated algorithms the remote sensing data can be used for monitoring. This requires well educated researchers and intense co-operation between all countries bordering the Baltic Sea.

In all Baltic Sea countries remote sensing research is carried out, some of them being world leading groups. However, most groups are relatively small and it is not feasible to organize courses at each university separately. The NordBaltRemS network functions here as an umbrella research school for Msc and PhD students and young researchers in marine remote sensing, and as a discussion forum for researcher and other experts in the field.
