    Íslenskur jarðvegur telst til eldfjallajarðar (Andosol) að langmestum hluta, en eldfjallajörð er jarðvegur sem myndast á eldvirkum svæðum heimsins. Eldfjallajörð hefur afar sérstæða eiginleika sem greina hana frá öðrum jarðvegsgerðum. Útbúin var einföld flokkun fyrir íslenskan jarðveg, sem m.a. byggist á alþjóðlegum flokkunarkerfum en einnig á vinnu Björns Jóhannessonar og Þorsteins Guðmundssonar. Flokkunin gerir greinarmun á i) jarðvegi auðna (glerjörð sem skiptist í melajörð, malarjörð, sandjörð og vikurjörð; ii) jarðvegi gróins lands með sortueiginleika (sortujörð, sem skiptist í brúnjörð, votjörð og svartjörð), iii) lífrænni mójörð og að síðustu iv) öðrum jarðvegi sem er margvíslegur að gerð. Í síðasta flokknum er bergjörð útbreiddust, en auk þess má nefna frerajörð sífrerasvæða og kalkjörð. Jarðvegskortið var unnið á grundvelli sniða og jarðvegssýna sem safnað hefur verið víða um landið. Kortið er á vektora formi og í mælikvarða 1:500 000. Það er m.a. hluti evrópska jarðvegskortsins. A soil map of Iceland: The Soil map classification separates between; 1) andic soils, which are Brown Andosols, Gleyic Andosols and Histic Andosols; 2) Vitrisols, soils of deserts, which are divided into Cambic Vitrisols, Gravelly Vitrisols, Arenic Vitrisols and Pumice Vitrisols iii) Histosols, and iv) other soil types such as Cryosols and Leptosols. The classification system is in part based on WRB system and Soil Taxonomy and earlier work by Björn Jóhannesson and Þorsteinn Guðmundsson (see English Summary and 1. table in http://www.moldin.net/uploads/3/9/3/3/39332633/jardvegskort_2.pdf). The map is in a coarse scale (1:500 000) and is not intended to use for particular points on the landscape. It is rather an overview. It has been incorporated into the EU soil database and the Circumpolar soil map.

    Dreifing hvítabjarna sem sést hafa á Íslandi í mismunandi mælihvarði. Þekja ni_G500v_hvitabjorn, punktalag. [Distribution of polar bear sightings in Iceland in different scales. Point layer ni_G500v_hvitabjorn.] Ekki er hægt að tala um hvítabirni sem íslenska tegund en þó hafa þeir tekið hér land af og til og teljast því til flökkudýra. Upplýsingar eru til um rúmlega 560 hvítabirni sem skráðir hafa verið hérlendis frá upphafi landnáms. Síðast varð vart við hvítabjörn við Höfðaströnd í Jökulfjörðum 2024. Viss ónákvæmni er þarna um að ræða því vafalaust hafa einhver dýr gengið hér á land án þess að menn hafi haft þar vitneskju um eða skráð sérstaklega. [Polar bears are not native to Iceland, although they do occasionally turn up in Iceland and are thus classified as vagrants. Information exists on just over 560 polar bears recorded as having arrived in Iceland from the beginning of human settlement on the island to the present day. This is a somewhat imprecise figure, since polar bears have undoubtedly come ashore without their presence going noticed, while bear sightings and encounters were not always documented in the past. The last polar bear observation was at Höfðaströnd, Jökulfjörður, Westfjords, in 2024. Table entries are in Icelandic.] Nákvæmni tíma [Accuracy of time]: varies depending on the source. If only the year of the sighting is known, you find this year under fitjueigindi 'ártal 1' (artal1). In case there are more details known, there are as well entries for fitjueigindir 'dags hvítabjarnakomur' (dagsHvitabjarnakomur) or 'ártið' (artid). If the year is not quite definit, there is an entry in fitjueigindi 'um' (um). Entries in both fitjueigindir 'ártal 1' and 'ártal 2' (artal1, artal2) define a timespan for the sighting. Nákvæmni staðarins [Accuracy of location]: varies depending on the source. All sightings for Íceland are grouped in the center of Iceland and the value for fitjueiginde 'nákvæmni XY' (nakvaemniXY) is '9000'. Sightings for Norðurland are grouped on Tröllaskagi, sightings for Norðvestur are placed in the center of the Vestfjords, sightings on Melrakki are grouped just off the north coast (nakvaemniXY = 3000 or 2000). If only the area is know, the data is placed in the center of the corresponding 10-km-reit (nakvaemniXY = 1000). If the location is known in detail, t.d. bæ, the entry for 'nakvaemniXY' is '100'. Sometimes the sources do not state the location of the sighting but the farm where the animal was processed [unnin]. And one has to keep in mind that a 'dot' in the data set can also represent an animal that has been in Iceland for a longer period of time and has traveled a longer distance. If there are several sightings for the same place or area, the entries are scatterd using a 1-km-reit system. Entries on age, sex, and size or weight are often missing. Fitjueigindi 'RM númer' (RMnumer) corresponds with the Natural History Collection of Náttúrufræðistofnun.

    The dataset comprises regional airborne radiometric measurements acquired in Greenland during 1975–1982 as part of systematic geophysical mapping programmes. The measurements were collected using aircraft-mounted gamma spectrometers and record natural gamma radiation from potassium (K), thorium (Th) and uranium (U). The surveys covered large parts of Greenland and were conducted to support regional geological mapping and mineral exploration. The data constitute a historical geophysical reference dataset for analyses of near-surface lithological variations and the distribution of radioactive elements.

    The dataset represents a layered 3D geological model of the Danish subsurface based on integration of reflection seismic data, borehole data, wireline logs and lithological information. The model comprises 17 stratigraphic units from the Upper Permian to the Danian and is structured as a layered digital elevation model (LDEM) consisting of 17 grid surfaces with a spatial resolution of 400 x 400 metres. The underlying data have been interpreted from seismic profiles and calibrated against deep wells, enabling the construction of depth and isochore maps for each unit. The dataset covers onshore Denmark and the inner Danish waters and represents the structural and stratigraphic framework of the Danish Basin and the northern part of the North German Basin. The model provides a basis for analysis of the geological evolution and spatial variability of the subsurface.

    The dataset contains aeromagnetic measurements acquired during 1993–1996 in East and North-East Greenland as part of the AWI-AEROMAG project conducted by the Alfred Wegener Institute (AWI). The measurements represent regional airborne magnetometry and include total magnetic field intensity corrected for diurnal variations and the main geomagnetic field. The survey was carried out to support geological mapping and tectonic analysis of eastern Greenland. The dataset constitutes an important geophysical reference for studies of crystalline basement rocks, sedimentary basins and structural features in the region.
