The Superficial deposits 1:20 000 / 1:50 000 data include material produced during the period 1972-2007 for land use planning, for the mapping and inventory of the natural resources as well as for environmental management and for scientific research. The main mapping scale has been 1:10 000. The data contains a sediment as a basal deposit at a depth of one metre. The minimum size of the basal deposit polygon is two hectares, with islands, mire and field enclosures, as well as geologically significant sites as an exception. The 0.4-0.9 m thick layers are described as overlying the basal deposit and, in geologically or economically significant cases, such layers could be even thicker. The minimum polygon size of the overlying deposit is usually four hectares. Thin covering layers under 0.4 m in thickness, which are difficult to delimit but effect an area of at least four hectares, are displayed as point data. Besides the deposits Quaternary geological formations formed in different ways, such as eskers and hummocky moraines, are described in the data. Other mapping sites such as small rock exposures, dunes and raised beaches are shown as point or line data. Coordinate reference system of the Superficial deposits 1:20 000 / 1:50 000 was transformed in March 2013. The transformation from Finnish National Grid Coordinate System (Kartastokoordinaattijärjestelmä, KKJ) Uniform Coordinate Frame to ETRS-TM35FIN projection was done by using the three-dimensional transformation in accordance with the recommendations for the public administration JHS154.

The EMODnet (European Marine Observation and Data network) Geology project (http://www.emodnet-geology.eu/) collects and harmonizes marine geological data from the European sea areas to support decisionmaking and sustainable marine spatial planning. The partnership includes 39 marine organizations from 30 countries. The partners, mainly from the marine departments of the geological surveys of Europe (through the Association of European Geological Surveys- EuroGeoSurveys), have assembled marine geological information at a scale of 1:50 000 from all European sea areas (e.g. the White Sea, Baltic Sea, Barents Sea, the Iberian Coast, and the Mediterranean Sea within EU waters). This data includes the EMODnet seabed substrate map at a scale of 1: 50 000 from the European marine areas. Traditionally, European countries have conducted their marine geological surveys according to their own national standards and classified substrates on the grounds of their national classification schemes. These national classifications are harmonized into a shared EMODnet schema using Folk's sediment triangle with a hierarchy of 16, 7 and 5 substrate classes. The data describes the seabed substrate from the uppermost 30 cm of the sediment column. The smallest cartographic unit within the data is about 0.01 km2. Further information about the EMODnet-Geology project is available on the portal (http://www.emodnet-geology.eu/).

This multiscale dataset include EMODnet seabed substrate maps at a scale of 1: 50 000, 1:100 000, 1: 250 000 and 1: 1 000 000 from the European marine areas, compiled in three subsequent projects running since 2009. Traditionally, European countries have conducted their marine geological surveys according to their own national standards and classified substrates on the grounds of their national classification schemes. These national classifications are harmonized into a shared EMODnet schema using Folk's sediment triangle with a hierarchy of 16, 7 and 5 substrate classes. The data describes the seabed substrate from the uppermost 30 cm of the sediment column. The data has been generalized into target scales of 1: 50 000, 1:100 000, 1: 250 000 and 1: 1 000 000. The smallest cartographic units within the dataset varies between 0.01 km2 and 4 km2 according to each scale.

Aineistossa esitetään 24 kalalajin sekä 2 rapulajin esiintyminen Suomessa. Rapulajeista toinen, täplärapu, kuuluu EU:n vieraslajiasetuksen mukaisiin EU:n kannalta haitallisiin lajeihin. Lajeista kuvataan yleislevinneisyys, sekä luokiteltuna tietona esiintymien alkuperäisyys, uhanalaisuus ja luonnonvaraisuus. Tiedot esitetään valuma-alueittain (kolmas jakotaso) ja merialuejaon mukaisesti.
