Hydrography (HY) Iceland is one of 12 themes in the European Location Project (ELF). The purpose of ELF is to create harmonised cross-border, cross-theme and cross-resolution pan-European reference data from national contributions. The goal is to provide INSPIRE-compliant data for Europe. A description of the ELF (European Location Project) is here: http://www.elfproject.eu/content/overview Encoding: INSPIRE version 4

The "Effective Drainage Area of the AAFC Watersheds Project - 2013" dataset is a geospatial data layer containing polygon features representing the areas of the Agriculture and Agri-Food Canada's (AAFC) Watersheds Project that could, for the entire project areas, be expected to contribute to surface runoff under average runoff conditions.

Local diatom species richness of Arctic diatom assemblages from stream scrapes, showing (left) richness as a function of latitude, and (right) site-specific richness. A LOESS smoother (blue line) with a span of 0.75 and a 95% confidence interval (grey shading) was applied to the data (left) to better highlight the general trend. Coloured circles on the map indicate species richness at the sampling sites. State of the Arctic Freshwater Biodiversity Report - Chapter 4 - Page 37 - Figure 4-10

Figure 3-6. The hypothesized effects of rising mean water temperature on biodiversity (as total species number) of Arctic freshwater ecosystems. A pulsed increase in gamma biodiversity (a) results from the combination of high eurythermal invasion and establishment and low stenothermic loss with increasing water temperature. A pulsed decrease in gamma biodiversity (b) results from the combination of low eurythermal invasion and establishment and high stenothermic loss. Rapid increases (c) and slow increases (d) in species diversity occur, respectively, with high eurythermal invasion and establishment coupled with high stenothermic loss or low eurythermal invasion and establishment and low stenothermic loss as temperatures increase. For simplification, barriers to dispersal have been assumed to be limited in these models. State of the Arctic Freshwater Biodiversity Report - Chapter 3 - Page 23 - Figure 3-6

EN: Lake and coastal waterbodies in Iceland. "Lake" means a body of standing inland surface water. "Coastal water" means surface water on the landward side of a line, every point of which is at a distance of one nautical mile on the seaward side from the nearest point of the baseline from which the breadth of territorial waters is measured, extending where appropriate up to the outer limit of transitional waters.

"Stöðuvatn" er kyrrstætt yfirborðsvatn. "Strandsjór" er yfirborðsvatn landmegin við línu sem dregin er einni sjómílu utan grunnlínu landhelginnar og nær inn að ytri mörkum árósavatns.

EN: Boundary of River Basin District(s) of Iceland as reported to WISE on 22.12.2018."River basin district" means the area of land and sea, made up of one or more neighbouring river basins together with their associated groundwaters and coastal waters, which is identified under Article 3(1) as the main unit for management of river basins.For further description of dataset fields and field values see GML schema here. http://dd.eionet.europa.eu/schemas/WFD2016/GML_RiverBasinDistrict_2016.xsd IS: Vatnaumdæmi Íslands miðað við skil inn í WISE upplýsingakerfið þann 22.12.2018.

Vatnsföll eru gjarnan flokkuð í þrjá flokka, dragár, lindár og jökulár eftir rennslisháttum. Mörg eru vatnsföllin þó af blönduðum uppruna vegna margbreytileika vatnasviða þeirra. Gagnasettið sýnir greiningu vatnasvæða í vatnafarsflokka, eftir því hvernig svæðið bregst við úrkomu og miðlar henni, og rennslisháttum vatnsfalla sem eiga uppruna sinn á viðkomandi svæði.
