File talk:Approximate chronology of Heinrich events vs Dansgaard-Oeschger events and Antarctic Isotope Maxima.png

--Dbasse63 (talk) 05:33, 23 October 2020 (UTC) For the benefit of those of us who are not technically proficient in the finer points of the glaciation periods and the North Greenland Ice Core Project it would be very helpful to add an explanation or legend that indicates exactly what the various vertical bands, different shadings and the letter/number combinations mean. A legend would be most helpful. I am sure there is significant and important information contained in this graph/diagram, but it is very opaque to the non-technical reader.
