Kartet viser utbredelsen av steinkobbe. Latin name: Phoca vitulina. Family: Phocidae. Distribution: Sub Arctic waters along the east and west coasts of both the North Atlantic and north Pacific. In Norway they occur in colonies along the Norwegian mainland coast and on Prins Karls Forland in Svalbard. The harbour seals occur mainly in nearshore areas that are protected against wave action.

DK model 2019 – Calibration statistics comprises spatial and statistical results from the calibration and evaluation of GEUS’ national hydrological model for Denmark. The dataset documents model performance for groundwater heads and stream discharge, including statistical measures such as RMSE and mean error for groundwater heads as well as WBE, summer WBE and KGE for streamflow simulations. The calibration was carried out using dynamic model runs and inverse parameter estimation with PEST based on observed groundwater heads and daily discharge data for the period 2000–2010. The dataset is intended for assessing the suitability of DK model 2019 for regional analyses, screening and further use. The calibration statistics describe model performance at national and regional scales and should not by themselves be used as documentation of local-scale model accuracy.

Nationwide geophysical database for environmental and raw material data, also known as GERDA (GEophysical Relational DAtabase). The database contains various types of geophysics, including geoelectrics, electromagnetics, borehole logs and seismic. All data is freely available for download on the GEUS website. The database is updated continuously.

The dataset presents Bouguer gravity anomalies on land and free-air gravity anomalies in Danish marine areas based on gravity measurements from the national gravity database. The Bouguer anomaly is terrain corrected and is used to investigate variations in subsurface mass distribution, while the free-air anomaly at sea reflects variations in the gravity field without full terrain correction. Gravity anomalies are expressed in milligals (mGal). The dataset was produced by DTU Space and represents a consolidated gravimetric foundation for geological and geophysical analyses in Denmark.

The North Atlantic current (red arrows) originates in the hot and salty Gulf Stream which flows out of the Mexican gulf and follows the east coast of the USA. When this current leaves the continental shelf and moves across the North Atlantic itâs often called the North Atlantic current. The North Atlantic current provides a significant amount of heat transport to northern Europe. This heat transport is greatest in winter because the current velocity is greater in that part of the year. The North Atlantic current keeps a very constant temperature and salinity throughout the year. It gradually looses heat and salinity as it flows towards the north east and gets mixed with colder and less salty water. At the south western part of the map where the current leaves the American continental shelf the surface temperature is 15-20 oC and the salinity is approximately 36. When it reaches the inlet to the Barents Sea the surface temperature is reduced to 5 oC in the winter and 10 oC in the summer, while the salinity stays at 35 throughout the year.The North Atlantic current continues into the Polar seas through the Fram Strait west of Svalbard and into the Barents Sea (pink arrows). When it reaches these areas its quickly chilled to 2-3 oC and the salinity sinks towards 34.7.The cooling of the North Atlantic current happens when it comes into contact with the colder and less salty Arctic current (blue arrows) that flows south west towards Svalbardâs east coast, south out of the Fram Strait and south out of the Davids Strait between Greenland and Canada. This current has salinity below 34 and the temperature is between -2 oC and +2 oC. In the same way as the North Atlantic current cools on the way north east the Arctic current heats up on its way towards the south west. The Arctic current does however give a significant colder climate around the coast of Greenland and along the Canadian Labrador- and Newfoundland-coasts compared to Europe coasts.Close to the coasts both on the eastern and western side of the North Atlantic there are lighter coastal currents with salinity between 25 and 34 (green arrows). In these areas both the temperature and salinity varies greatly throughout the season. They are warmer then the North Atlantic current during the summer and colder during the winter. In the same way the salinity varies greatly throughout the year because of the varying freshwater runoffs from land.

DK model 2019 – Simulation results comprises calculated hydrological results from GEUS’ national hydrological model for Denmark. The dataset contains derived results from model runs with DK model 2019, including calculations of water balance, groundwater recharge, impacts of water abstraction, groundwater drawdown, streamflow impacts and changes in flow-related indicators. The results include, among other outputs, comparisons between scenarios with current abstraction and reference scenarios without abstraction. The dataset is used for regional assessment of hydrological conditions, screening of water resource and impact conditions, and documentation of model-calculated results. The results are model-based and should be used with due consideration of the regional purpose, model uncertainties and limitations of DK model in relation to local-scale applications.
