There is some great content online about how to tackle the challenge of inferring climate history on Mars from polar ice deposits, and what future missions may be required to get the data needed to do this:

(Check out great videos from first workshop)

It was a very interesting and enriching experience to be part of the second workshop, and I look forward to following the progress on this into the future. Other workshop content is also available and these institutes are a remarkable way to exchange on some of the grand topics in space science. Thanks to all who facilitated and organized the effort.
