Talk:German Continental Deep Drilling Programme

Possible improvements to article
A graphic of the temperature plot would be a useful addition. Also some discussion as to why the thermal gradient in Earth's outer crust is at least 20 times steeper than in the hot regions of the mantle. There is nothing like a linear conduction plot all the way from the core. If you look at data from in the deeper half of this 9Km deep borehole* and extrapolate it to the surface you do indeed get close to the mean daily minimum temperatures of the surface. The article could address the issue: How does it "know" down there what temperature to aim at?

The text is really quite good
But, Germanic idiom is pervasive and more than I can fix myself in a quick once over, so flagged for a copy edit, which would be quicker by someone who knows the subject to begin with. &mdash; MaxEnt 01:00, 25 November 2017 (UTC)
