Daily and monthly surface wind analyses are determined as gridded wind products over global oceans, with regular spatial resolution of 0.25° in latitude and longitude. They are estimated from scatterometer wind retrievals (L2b data). According to the scatterometer sampling scheme, the objective method allowing the determination of regular in space surface wind fields uses remotely sensed observations as well as ECMWF analyses. The calculation of daily estimates uses ascending as well as descending available and valid retrievals. The objective method aims to provide daily-averaged gridded wind speed, zonal component, meridional component, wind stress and the corresponding components at global scale. The error associated to each parameter, related to the sampling impact and wind space and time variability, is provided too. Monthly wind analyses are calculated from daily estimates.

The Marine Hard Substrate dataset maps areas of rock or hard substrate outcropping or within 0.5m of the sea-bed. The interpretation was based on a variety of data sourced from within the British Geological Survey and externally. Data consulted includes archive sample and seismic records, side scan sonar, multibeam bathymetry and Olex datasets. The distribution of hard substrate at the seabed, or within 0.5 m is important in dictating the benthic assemblages found in certain areas. Therefore, an understanding of the distribution of these substrates is of primary importance in marine planning and designation of Marine Conservation Zones (MCZs) under the Marine and Coastal Access Act, 2009. In addition, a number of other users will value these data, including marine renewable companies, aggregate companies, the fishing and oil and gas industries. In order to address this issue it was necessary to update British Geological Survey sea-bed mapping to delineate areas where rock, boulders or cobbles are present at, or within 0.5m of the sea-bed surface. A polygon shape file showing areas of rock or hard substrate at, or within 0.5m of the sea-bed has been developed. The dataset has been created as vector polygons and are available in a range of GIS formats, including ArcGIS (.shp), ArcInfo Coverages and MapInfo (.tab). More specialised formats may be available but may incur additional processing costs.

The ambition of the XYLOSYLVE platform is twofold, to constitute a visible forest research facility for setting up innovative forestry practices and to build a scientific infrastructure of national and international interest for terrestrial ecology. XYLOSYLVE is an ensemble of three long-term complementary field experiments and laboratory facilities associated with. Each experiment is spatially distinct from the other but all are co-located in the INRA Hermitage area close from Bordeaux city. The experiments are designed to testing forest management alternatives dedicated to biomass and wood production in Atlantic conditions as follows: 1) Three large plots (8ha) are manipulated according to three management alternatives (Pine-Eucalypt mixture, pure enhanced Pine variety and environment-friendly Pine standard) and equipped with automated instrumentations for monitoring biogeochemistry in the different compartments of ecosystems (soil, soil solution, vegetation, atmosphere). The equipment and protocols implemented are installed in collaboration with the ICOS project according to common quality assurance standards (ICOS site Class 3). These 3 plots are not replicated here. 2) A fully randomised 4-blocks experiment includes the same three treatments than above and 5 additional treatments including various levels of species mixture, fertilisation, soil preparation and legumes introduction. The 32 plots are further split according to no till - deep tillage to a total of 64 subplots each covering 0.12 ha to a total of approximately 40ha. 3) The third experiment includes 2 levels of fertilisation (control - full annual NPK inputs), 2 levels of irrigation (control (rainfall) - daily irrigation at PET) and 2 species (local Pine species - Eucalypt hybrid) replicated in four blocks and covering an area of 8 ha (plot unit ~0.25ha). XYlosylve serve as a long term research and experimental site for temperate planted forest systems in close connection with a regional network of forest experimental sites where feasibility of new forest management alternatives is evaluated. The interest of XYLOSYLVE is double: - Allow the long term monitoring of the functioning of biophysics and biogeochemistry of new forest ecosystems with high production potential. Offer to the scientific community and to the forest-based industry a common platform to gather scientific data and wood samples and test ecosystems to better understand their dynamics and their environmental impacts; - Assess durability and environmental performance of various management options for dendro-biomass production systems (symbiotic nitrogen fixation, phosphorus uptake, long term fertility, water and energy use efficiency, evaluation of vulnerability to biotic risks /insects, pathogens/ and abiotic risks/wind, drought/ …).

Gravel and Hard Rock Aggregate Database at NGU contains information on most sand, gravel and hard rock aggregate deposits and extraction places in Norway where the raw material are used for building and construction activities. In addition, the WMS/database gives an overview of stone tips. The database also provides information on land use, volume, operating conditions, manufacturers, quality and how important resources are as raw material to building engineering purposes
