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.

The service contains GEBCO, VMAP0 data at higher zoom levels, and data from the national mapping authorities of Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and USA. The service has been designed for use within the ArcticSDI Geoportal.

The data set shows data on ship traffic in the period 1 July 2016 to 30 June 2017 distributed in a grid of 250 x 250 meters. The data show all ships with class A AIS transponders. The data source is Havbase. The stronger the color the more passes of the route in the period. This provides a good overview of the large traffic flows.

The map shows where the ice edge is now, meaning the boundary between solid ice and floating ice. The Norwegian Meteorological Institute updates the map every working day, Monday to Friday.

This file contains output from Control member. Contains most forecast parameters on surface, model level and pressure levels The Norwegian Meteorological Institute has provided forecasts of the weather in the High North for a long time. Our Development Centre for Weather Forecasting has developed a high-resolution model that forecasts the weather in this area for the next three days. The model is called AROME-Arctic and has been running since November 15th, 2015. The geographic resolution is 2.5 kilometres, which is the same as in the model that the Norwegian Meteorological Institute uses to forecast the weather elsewhere in Norway. AROME-Arctic gives a detailed representation of processes on the ground and in the atmosphere. In addition to Svalbard and northern Norway, the model also covers a large area of sea, which is a challenge due to the sparsity of observations. Thus, satellite observations are particularly important for this model.
