In other words, they are not there to learn, they are there to prove, and that affects their interpretations and conclusions.
I think that's a jaded comment, sorry. Most of the work done on the cores will be basic research: measuring the oxygen isotopes, conductivity, sulfur content etc. in each layer, and then analyzing that data. Correlating it with known causes, known cycles and seeing what doesn't fit. Then the job of science is to try and figure out what doesn't fit and finding a way to make it fit.
I think the guys doing the drilling and analyzing the core won't be in the business of interpreting. That'll be left to the folks back home in their warm comfy offices.
