Water Transparency Depth (VELMU)NÄKÖSYVYYS (VELMU)
NÄKÖSYVYYS (VELMU)Water Transparency Depth (VELMU)
This dataset provides raster data on water transparency (Secchi/light attenuation depth) produced by the Finnish Environment Institute (Syke) for the VELMU programme, Finland's inventory programme for underwater marine biodiversity. It describes the attenuation of light caused by the combined effect of substances present in the water, indicating the depth to which light penetrates. The dataset covers Finnish marine and coastal waters and supports mapping and assessment of underwater marine habitats and biodiversity.NÄKÖSYVYYS (VELMU) Näkösyvyys on Sykessä Velmu-ohjelman (Vedenalaisen meriluonnon monimuotoisuuden inventointiohjelma) tarkoituksiin tuotettu rasteriaineisto. Aineisto kuvaa valon vaimenemista säteilyyn vaikuttavien aineiden yhteisvaikutuksesta, eli veden läpinäkyvyyttä tiettyyn syvyyteen asti 30...
