Google Map of the Topography of the Thermohaline Circulation of the Oceans.



With the above map, you can zoom in close to see how the submarine topography affects the Thermohaline Circulation of the oceans and its effect on our climate. 

One of the things that bothered me when creating my Google Map of Oceanic Trenches and Other Undersea Phenomena, is that NASA's Thermohaline Circulation map (shown below) that was featured on Wikipedia's Oceanography page did not seem to factor in the submarine topography shown in Google Map or any submarine volcanoes or thermal vents. So I just had to plot the Thermohaline Circulation in Google Map to see what the difference was and plot any submarine volcanoes and thermal vents along the path. The NASA map is oversimplified. It inadequately represents the area in Indonesia where the surface current weaves between the islands and how it aligns with nearby volcanoes. You don't see in NASA's map how the deep current sweeps down the west side of the mid Atlantic Ridge. The NASA map makes the North Atlantic deep water formation look more pointed than it really is. NASA's map looks like the currents are real smooth rather than twisting between topographic features. However, soon after publishing this map, I discovered a NASA video with a totally different current structure which in many areas conflicted with the map below. Thus, I had to revise my map to reflect the change.

One interesting point the map reveals is that those areas where the Thermohaline Circulation comes near to populated land masses have an impact on the Climate-Density Vulnerability Index. And, the impact of melting glacier fresh water flows in Greenland, and volcanic activity along the circulation can impact on climate change.
