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 decision- making and sustainable marine spatial planning. The partnership includes 36 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 1:250 000 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 1:250 000 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 data has been generalized into a target scale (1:250 000). The smallest cartographic unit within the data is 0.3 km2 (30 hectares). Further information about the EMODnet-Geology project is available on the portal (http://www.emodnet-geology.eu/).

The data set relating to overall mapping of national peat resources contains by focus area those mires over 20 ha in extent that are most important from a peat production perspective. Since 1975 additional smaller areas have been included as required. For each mire, there are data on mire type, peat type, peat reserves, peat physical properties, mires that are suitable for peat production, peat quality and exploitable peat reserves. This information is published in municipality-specific peat investigation reports that present general information on each mire investigated and their applicability to energy, horticultural and environmental peat production as well as to protection purposes, among other uses.

The Rock Geochemical Database of Finland data set describes the concentrations of major and trace elements in the bedrock of Finland. In all, 6544 samples were analysed for the total and partial concentrations of 57 elements using several different methods (XRF, ICP-MS, ICP-AES, GFAAS). The samples were taken during 1990-1995 with a mini-drill from rock that was as unaltered as possible. The sampling density varies between one sample per 30 km2 and one sample per 120 km2. The chemical analyses of the data were performed during 1992-2001. The reproducibility of the analytical results and the analytical drift were estimated using 375 duplicate sample pairs. The lowest reliable concentration was determined for each element and analytical method. In addition to the chemical concentrations, the database contains spatial data and several geological attributes for each sample. The data set and its manual were published in 2007 and they are available via the web site of the Geological Survey of Finland (GTK).

Sedimentation rates are part of EMODnet (European Marine Observation and Data network) Geology, Work Package 3 (WP3) Seabed substrate. The objective of WP3 is to compile all available seabed substrate information on a scale of 1:100 000 or finer from all European marine areas, and to update sedimentation rate data collected in the previous phases. WP3 has compiled and harmonized available information on the rate of sedimentation on the seafloor. The information on sedimentation rates for recent sediments is presented as point-source information. Estimations of modern sedimentation rates (centimetres/year) can be based e.g. on established historical records of anthropogenic radionuclides (e.g. 137Cs and 241Am), polychlorinated biphenyls (PCBs), lead (Pb) and stable lead isotope (206/207Pb ratios). Sedimentation rate estimations can be based also on varve/laminae counting, radionuclide 210Pb and 14C decay dating methods. In addition stratigraphic marker horizons, like in the Baltic Sea, horizons formed by documented Major Baltic Inflow (MBIs) events (Moros et al. 2017), can be used in the estimations. Project partners have delivered information on sedimentation rates available in their national waters including their EEZ. The focus is on the present-day sedimentation rates. That means sediment accumulation to the seabed over the past decades, since AD 1900 or so. Further information about the EMODnet-Geology project is available on the portal (http://www.emodnet-geology.eu/).

The Superficial deposits of Finland 1:1 000 000 is based on 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and their Resources (Sheet 1, Western part)' mapping data. This data is also based on the 1984 map 'Quaternary Deposits of Finland' (1:1 000 000) in the “Geologia” (Geology) folio of the Atlas of Finland, 5th edition (123-126, 1990). Joint scientific and technical planning for the map of the 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and their Resources' was begun in 1987 while work on the map started in 1988. No field mapping was done for the map, rather the 1:1 000 000 Quaternary map printed in 1984 was supplemented with new data partly obtained from rock aggregate studies and partly from information on superficial deposits gathered in other superficial mapping projects. The map 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and their Resources' was printed in 1993. The map shows the superficial deposits with colours and symbols and these are classed according to their mode of geological development. The deposit classes are as follows: pre-Quaternary bedrock exposures (no Quaternary layers); boulder field, physically weathered bedrock; gravelly and sandy till; silty till; clayey till; hummocky moraine ; moraine complex; esker, delta, sandur, sorted marginal formation; interlobate formation (esker); till-covered esker / other till-covered gravel and sand deposit; gravel and sand deposit peripheral to eskers; littoral gravel and sand deposit; fluvial deposit; homogeneous clay and silt deposit; layered (varved) clay and silt deposit; peat deposit. Additionally, drumlins, end moraines, aeolian deposits, and sites of gravel, sand, clay and peat extraction as well as gold panning areas have been indicated with symbols. The data set was converted to a digital format to meet the needs of the OneGeology-Europe Project for a printed map in 2009. This data did not include drumlins, end moraines, aeolian deposits, and more important sites for the exploitation of superficial deposits (sites of gravel, sand, clay and peat extraction as well as gold panning areas). In accordance with the 1984 Quaternary map (1:1 000 000) the minimum size of the deposit polygon is generally one square kilometre. In nature the size of superficial sedimentary deposits is usually smaller than one square kilometre and therefore the most common deposit type in the area is shown in the polygon. In places, deposits smaller than a square kilometre that are significant from a superficial perspective have been noted. As a rule, the narrowest point of the deposit polygon was 0.5 km and in important cases, for example on eskers, 0.3 km. As an exception, the size of small eskers has been exaggerated. Coordinate reference system of the Superficial deposits of Finland 1:1 000 000 was transformed in October 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 water layer which were used in the OneGeology-Europe project was replaced in 2015 with the more accurate water layer of the Topographic database 1:55 0000-1:500 000 (DVE3) from ICT Agency HALTIK.
