I prefer my tree cores to be black oaks, middle-aged, with some nice big rings to show me. Alright, fine, I can deal with some smaller rings every now and then. As long as they’re some nice marker rings. Unfortunately, the trees don’t seem to be trying to impress me.]]> http://blogs.ei.columbia.edu/2013/03/28/ill-go-on-a-cross-date-if-you-show-me-some-rings/feed/ 0 http://blogs.ei.columbia.edu/2012/12/05/tree-rings-and-teachable-moments/ http://blogs.ei.columbia.edu/2012/12/05/tree-rings-and-teachable-moments/#comments Wed, 05 Dec 2012 20:42:47 +0000 Guest Blogger http://blogs.ei.columbia.edu/?p=32783 Nicole Davi, a postdoctoral scientist at the International Research Institute for Climate and Society and the Lamont Doherty Earth Observatory, thinks tree rings are an ideal way to motivate students to collect and analyze data as well as to learn about climate change.]]> http://blogs.ei.columbia.edu/2012/12/05/tree-rings-and-teachable-moments/feed/ 0 http://blogs.ei.columbia.edu/2012/06/17/finally-some-true-turkish-delight-discovery-of-some-tasty-oaks/ http://blogs.ei.columbia.edu/2012/06/17/finally-some-true-turkish-delight-discovery-of-some-tasty-oaks/#comments Sun, 17 Jun 2012 15:53:32 +0000 Neil Pederson http://blogs.ei.columbia.edu/?p=28096 After a few days of mild frustration, the sampling of potentially old umbrella pine lifted our spirits and put us in a good frame of mind to conduct our last day of research in the temperate rainforest region of northeastern Turkey.

Here altitude drops from more than 3900m to sea level in a less than 30 miles. Both the orographic effect of mountains and the lake effect (well, better sea effect) cause very high precipitation allowing for rich and productive temperate forest to grow.]]> http://blogs.ei.columbia.edu/2012/05/15/what%e2%80%99s-a-tree-like-you-doing-in-a-place-like-this-or-west-meets-east/feed/ 2 http://blogs.ei.columbia.edu/2012/05/11/tree-ring-science-in-a-log-yard/ http://blogs.ei.columbia.edu/2012/05/11/tree-ring-science-in-a-log-yard/#comments Sat, 12 May 2012 03:31:04 +0000 Neil Pederson http://blogs.ei.columbia.edu/?p=26527 The cool, snowy weather really put a crimp in our plans.

What kind of a tree might that be? As with many things, one person's charismatic megaflora is another person's tree. For myself, a tree that would draw and hold my attention as a younger person/student is very different than my current definition of a charismatic tree. ]]> http://blogs.ei.columbia.edu/2012/03/18/charismatic-megaflora-what-do-old-trees-look-like/feed/ 4 http://blogs.ei.columbia.edu/2012/02/12/year-without-a-winter/ http://blogs.ei.columbia.edu/2012/02/12/year-without-a-winter/#comments Sun, 12 Feb 2012 22:08:45 +0000 Neil Pederson http://blogs.ei.columbia.edu/?p=22727 No, of course not. Do not suggest anything like that to Alaskans, or Europeans where hundreds have died, or Inner Mongolians, or Koreans.
