Radartidalflats: Sediment characteristics of tidal flats in Westerschelde, The Netherlands, obtained from space-borne Synthetic Aperture Radar (SAR) [Sedimentkarakteristieken van getijdenplaten te Westerschelde verkregen via satelliet "Synthetic Aperture Radar" (SAR)] Citation van der Wal D. 2005: Sediment characteristics of tidal flats in Valkenisse, The Netherlands, obtained from space-borne Synthetic Aperture Radar (SAR). Netherlands Institute of Ecology; Centre for Estuarine and Marine Ecology, Netherlands. Metadata available at http://mda.nioo.knaw.nl/imis.php?module=dataset&dasid=1214. https://marineinfo.org/id/dataset/1214 Availability: Unrestricted The data are freely available to anybody and may be used for any purpose. Usage acknowledgement may be required Description Information on sediment characteristics is required for habitat mapping and for assessing the distribution of macrobenthos. This dataset contains data on a range of sediment characteristics, obtained from satellite imagery.
