We were just walking into the Northeast Natural History Conference, along with Dario and Jackie from the Tree Ring Lab. When I pictured my freshman year of college last summer, I pictured a lot of things. I did not picture getting to go to a conference to present a poster on my own research.]]> http://blogs.ei.columbia.edu/2013/05/06/out-of-the-woods/feed/ 0 http://blogs.ei.columbia.edu/2013/04/05/visual-skateboarding/ http://blogs.ei.columbia.edu/2013/04/05/visual-skateboarding/#comments Fri, 05 Apr 2013 23:57:27 +0000 Guest Blogger http://blogs.ei.columbia.edu/?p=35454 “You can do math on excel?” I ask. I immediately imagine a face-palm response, but Dario, one of my advisors, is nice enough to hide it. I’ve collected tree core samples, I’ve prepared them and cross-dated them. Now what? Oh, right.

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/2012/11/04/the-zen-of-sanding/ http://blogs.ei.columbia.edu/2012/11/04/the-zen-of-sanding/#comments Sun, 04 Nov 2012 16:56:13 +0000 Guest Blogger http://blogs.ei.columbia.edu/?p=31837 By Ana Camila Gonzalez “But can’t you see the rings already?” I ask, wondering why I’ve been asked to sand a sample- it sounds to me like one would damage a sample by subjecting it to the mechanical screech of a sander.   “Yes, but under the microscope they look foggy if you don’t sand [...]]]> http://blogs.ei.columbia.edu/2012/11/04/the-zen-of-sanding/feed/ 2 http://blogs.ei.columbia.edu/2012/09/21/dipping-your-feet-in-the-water-a-first-years-experience-with-fieldwork/ http://blogs.ei.columbia.edu/2012/09/21/dipping-your-feet-in-the-water-a-first-years-experience-with-fieldwork/#comments Fri, 21 Sep 2012 14:07:48 +0000 Guest Blogger http://blogs.ei.columbia.edu/?p=30765 My feet are soaking wet and I’m playing a game of Marco Polo, but I’m nowhere near a pool.

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
