Dear authors:
As you have seen, the reviewers' comments were quite detailed and offer a number of suggestions on how to improve the manuscript, particularly the flow of the paper. Both reviewers indicated that the individual sections are not well connected. Please consider all the comments of the reviewers carefully when you are re-structuring your manuscript. Please provide also a letter stating point-by-point how you dealt with the reviewers' comments in the revised paper.
Your revised paper will be sent out to the same reviewers again.
Please let me have your revised manuscript at your earliest convenience.
Best wishes, Gerhard Herndl

Reviewer 1 offers some minor comments. I request that you take again a look at your revised version and amend and correct these minor issues. After receiving the final version of your manuscript with the requested minor changes, I will accept the manuscript right away.
