Both in lakes, large ponds, water reservoirs and public waters, the growth of blue-green algae constitute a formidable problem. These types of algae represent a group of bacteria, known as cyanobacteria. They give rise to a distinctly foul odour and are also known to produce toxins. These toxins can cause various discomforts and illnesses. As well as causing skin irritations they are even suspected to be involved in the occurrence of liver cancer. Each year, numerous lakes are forced to close for all recreational use due to the growth of blue-green algae. In response to this global problem, a substantial annual budget is being released by governments with the purpose of keeping lakes clear from blue-green algae. Todays traditional algae controlling methods (e.g. aeration, chemical or biological additives, ultrasound and others) are not sufficiently effective when it comes to larger waters. There are high labour costs associated with the need for frequent maintenance and dosage. Another concern is the environmental impact in particular cases, especially when chemicals are used. The ClearWaterPMPC project offers solutions to these problems by providing an environmentally-friendly technology that is based on ultrasound. Ultrasound is a well-known and proven technology for the treatment of algae. In contrast to currently available ultrasound based algae control systems, the ClearWaterPMPC project will be more cost-effective due to its low operation and installation costs. It will have an implemented online lake monitoring system and the possibility for remote control of specific control parameters. The system will also be independent of power supply from shore, since it will be self-supporting of power through solar panels and/or windmill generator. The technical issues that will be encountered in the development work demand expertise at a high level in the areas of Ultra Sound, electronic design and IT-systems. In addition, the project requires highly skilled re

The GENESIS Project has the objective of providing Environment management and Health actors with an innovative solution based on advanced ICT. Relying on interoperability standards and harmonization process, GENESIS helps to constitute complex information networks, by combining benefits of various information systems with a collaborative systems approach. The proposed generic solution allows easy deployment and customization to thematic needs on a wide range of applications, at regional, national or Europe levels for various thematic fields. The main benefits of GENESIS solution are two-fold :-to improve and facilitate actors daily practices in relation with the management of environmental data; -to perform an essential step in the deployment of the Single Information Space for the environment in Europe. The GENESIS solution will be validated through dedicated scenarios addressing thematic fields of Air Quality, Water Quality and their impact on Health. For the final benefits and information of European citizens, the needs of Environment and Health stakeholders are covered through fundamental services like : -environment monitoring,\n-multi-criteria finding of the information; -visualization and combination of static or near-real-time information; -fusion of various sources of environmental data; -correlation between environmental with health data; -support of decision making processes; -support of the risk management and response to crisis; -near-real-time information of citizens. The GENESIS generic solution is open and sustainable as based on de facto and emerging standards (OGC, OASIS, INSPIRE,...). Moreover, the GENESIS project development integrates current state of the art and innovative researches of major EC or ESA projects. GENERIS project represents an important step in operational environmental management in Europe thus paving the way to an effective wide deployment of the solution as part of the future Single European Information Space for Environment.

The study focused on the evaluation of probable changes in the severity of sea ice conditions occurring in 3 selected areas of the Baltic Sea: the Gulf of Bothnia, Gulf of Finland and the Southern Baltic Sea up to the year 2100. The areas have been chosen due to the high intensity of marine traffic (the Gulfs-of Bothnia and of Finland) and due to differences in sea ice conditions; winters in the Gulf of Bothnia were characterized as the most severe, whereas in the Southern Baltic were classified as the mildest ones. Consequently, three scenarios were taken into account in the study: A2 (slow rate of global economic development, market scenario), A1B (regional scenario, rapid economic development, with ecological priorities), B1 (sustainable, median economic development with strong ecological priorities), all three constructed on the basis of Special Report on Emissions Scenarios (SRES models of greenhouse gas emission). The probable changes of sea ice conditions expressed as severity index S were calculated from these models. The main results of the investigation are as follows, the variety of sea ice conditions occurring in specific regions of the Baltic will remain stable (i. e. the most severe winter conditions will still occur in Gulf of Bothnia, while the mildest in the Southern Baltic Sea). The most significant changes are likely to occur in the Southern Baltic, where some winters without ice cover in the Vistula Lagoon may happen. Nonetheless, some extremely severe winters will occur and also within specific seasons more winters with a lower number of days with ice will occur. © 2012 Pleiades Publishing, Ltd. Source

The main objective of the proposed project GLOWASIS is to pre-validate a GMES Global Service for Water Scarcity Information. In European and global pilots on the scale of river catchments, it will combine in-situ and satellite derived water cycle information and more government ruled statistical water demand data in order to create an information portal on water scarcity. This portal will be made interoperable with the WISE-RTD portal. More awareness for the complexity of the water scarcity problem will be created and additional capabilities of satellite-measured water cycle parameters can be promoted, but also directly matched to user requirements. By creating the user-scientist community, GLOWASIS will guide earth observation scientists to efficient innovation for the specific purpose of water scarcity assessment and forecasting. By linking water demand and supply in three pilot studies with existing systems (EDO and PCR-GLOBWB) for medium- and long-term forecasting in Europe, Africa and worldwide, GLOWASIS information will contribute both in near-real time reporting for emerging drought events as well as in provision of climate change time series. By combining complex water cycle variables, governmental issues and economic relations with respect to water demand, GLOWASIS will aim for the needed streamlining of the wide variety of important water scarcity information. Infrastructure is set up for dissemination and inclusion of current and future innovative and integrated multi-purpose products for research & operational applications. The service will use data from GMES Core Services LMCS Geoland2 and Marine Core Service MyOcean (e.g. land use, soil moisture, soil sealing, sea level), in-situ data from GEWEX initiatives (i.e. International Soil Moisture network), agricultural and industrial water use and demand (statistical AQUASTAT, SEEAW and modelled) and additional water-cycle information from existing global satellite services.

Knowledge of characteristics of future climate is essential to create adaptation plans. Numerical models can provide such information but an important issue is the correct assessment of reliability. This important problem can be solved by evaluating the ability of a model to reproduce past climate. It is assumed that the type and amount of error in the reference period is transferred to a scenario period. In this paper, the reconstruction of precipitation in 1971-1990 period by models selected from the EU ENSEMBLES project was analyzed. Analyses were subjected to precipitation conditions described by climatic indices based on daily sum of precipitation. Climate indices maps were compared by two methods. The first method is called optical flow method, and consists of assessing the parameters of a local transformation of fields. The second method uses the cluster analysis technique to a combined field consisting of reconstructed and reference values. These methods allow to perform an objectified evaluation of climate simulations. Source
