Addendum:


Comments of the C.A.S.E. meeting, Kiel (GeoMar) April 29th and 30th, 2013.
John T. Andrews, University of Colorado

May 10th, 2013

For a number of reasons I was not abled to attend the 1st two C.A.S.E. meetings, but was present at the 2012 meeting in Amsterdam.  As might be expected, the graduate student presentations had improved significantly in terms of both content and interpretation. What has struck me over the time of my involvement with C.A.S.E. is how fortunate are these PhD students---because of the “course” structure of C.A.S.E. it is difficult to imagine that there are any paleoclimate oriented  students within the EU who have had a better and more thorough training. What was notable  was the camaraderie shown by the group, and one hopes that in say 5 years or so that several of these young scientists will be working together on Arctic or other related paleoclimate issues. These future associations will be a robust measure of the long-term success of the C.A.S.E. experiment. It will also be interesting to see whether the current group of senior investigators will continue some degree of co-operation on common research issues once C.A.S.E. is finished---I would hope that will be the case.

There was one area of the presentations, and possibly the training, that I think could be improved, and that is in the area of quantitative data analysis. As I taught both undergraduate and graduate courses at the University of Colorado in “Data analysis for Earth Scientists” this is an area of especial interest for me, hence I admit that my comments might be somewhat biased or even opionated! My concern is not just for the C.A.S.E. PhD students but at a more general level, including U. Colorado. We have entered a “data rich” environment in Earth Science and in paleoclimate studies. The graduate presentations all indicated that they had amassed a great deal of data from a variety of laboratory analyses. The data were well presented but I was struck by the contrast between the rigors of the laboratory techniques and many of the relatively unsophisticated subsequent statements----i..e. use of terms such as “quiet similar” and I am not sure that I ever heard “null hypothesis.” This issue became more evident in the final discussions of how to integrate the various data sets on common cores, especially if the sampling and data were not generated from the same levels (=depths) in the core(s). All of us are lucky in today’s environment, in that for most purposes there are a variety of excellent statistical packages available for both Apple and Windows’ users. There are, however, still a number of critical issues that are frequently ignored or not even mentioned in many common packages (SPSS etc), such as the “closed array” issue (also termed the constant sum issue), which simply notes in % data that if one species is increasing, one or more others must decrease, hence correlations must be handled with care.


I would also note that nearly all the presentations deal with the variations of data through time, hence some understanding and usage of time-series analyses would be extremely useful, even the application of the simple “runs test”. It is probable that several students already have these tools but it did not come across very clearly in the presentations.


I suspect, hope, that this area will be more adequately addressed in the dissertations.

However, apart from this caveat, I thought the presentations were very effective and some of the graphics were striking.


Congratulations to the PIs and the graduate students---I learned a great deal.
