Kind-of Comment 23 & 32: Icy cherries?

I think this is for @lawinslow. I'm curious to see what you get.

This blog looks super cool, not sure if you'll find this post useful for your analysis, but a gam might help pull out weird relationships.

Comment 23

1. Comment: It's difficult to know how important the results are; since only two data sets were analysed/available it's difficult to know how representative the study locations are of other lakes and rivers. It's also possible that these two data series have biases in event definitions between older and newer data and possible that there are anthropogenic influences, such as warm water discharges that could bias results. The authors did give evidence of consistency with other types of data series from previously published work. Previous related work is well cited.

Cherries might help with this.

Comment 32

1. Comment: Line 77-How can you be sure that direct human influences such as warm water discharges or mechanical ice break-up are not at least partially responsible for trends? Also, how do you know that the definition of ice dates at both sites have stayed constant over time, particularly for the older periods? This is particularly important since only two time series are analyzed in this article.

@lawinslow I think it's fair to say that if we haven't analyzed cherries yet, we won't be doing it at all.
