Good luck with your ice core data projects this weekend. Let us know if you run into problems. The point is to learn how to deal with and look at real data from one of our climate proxies, in this case, ice! Some banging of the head against the wall is required, but if you start getting a headache contact us, post on the blog, contact classmates and hopefully we can have some fun with this.
The assignment, figure of Vostok del18O periodicities that we discussed at the end of class and the code that generated said figure are all up on the class wiki.
Cheers (with plenty of ice in your glass),

Im having a hard time finding what standard the dO18 values are compared to (in Mt. Logan data and Dasuopu data).
GROUP NOTES
I think we can combined our graphs and only need one. If we focus on d18O and sulphate from each ice core from similar years (1730-1990). That way we can build one graph with the same x-axis time (years), two series on y1-axis d18O (per mil), and two series on the y2-axis sulphate (ppb).

Right that is what I was thinking aswell. I am going to make a variety of charts and email them out to see if I was on the right track.
ReplyDeleteA note to everyone: A couple people have been having trouble getting Excel to interpolate where the time sequence does not match up between cores. If you are just trying to take up space between points (even interval points like one year)then you can fill in empty cells with =NA() and then the plot will be continuous. Hope the project is going along ok for all!
ReplyDeleteThank you for the important note about filling empty cells with =NA(). Just found Lynda.com on UNM's home page right column that has two tutorials on graphing - for free.
ReplyDeleteIt's a shame that the lecture (and all similar lectures) was not taped for those of us who could not attend.
