Temperature of the North Atlantic Ocean
This movie takes us on a journey through the temporal and spatial variations of the North Atlantic Ocean temperature.
During the first part of the animation the depth distribution of temperatures can be seen, starting from the very cold (below 2 deg.C) bottom waters and progressing up to the surface, where water is warmed under the heating effects of the sun and atmosphere. The evolution of the upper ocean temperature is then shown over the course of 1 year. Temperatures are higher in the Subtropical region and in the western Atlantic, where the Gulf Stream stands out as a pronounced narrow warm current flow northwards along the North American coast. The coldest waters are seen further north at the periphery of the Subpolar gyre progressing south along South Greenland and West Canada.
The second part of the animation shows us the vertical distribution of ocean temperature through depth-longitude sections. Moving from south to north, the latitudinal variations of the vertical distribution can be appreciated. A stop is made at a latitude north of the Gulf Stream and the time evolution over the course of 1 year is again repeated. Large amplitude fluctuations can be seen only in the top 1000m of the water column.
