With this map you can zoom in close to see how the submarine topography affects the Thermohaline Circulation of the oceans and it's 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.
