Seeing rivers from underwater

3/25/2013

 
A cool set of underwater photographs of rivers from National Geographic.  One of our study sites (Blue Hole Spring in the Ichetucknee River, FL) is included.

I will note that Blue Hole has fairly high nitrate concentrations, despite it's otherwise excellent condition.  Which is an example of why we think that nitrate contamination may not be the whole story in Florida Springs.

Durham is a great place to live

1/18/2013

 
This brief tour of Durham in the NY Times gives some sense of how much is going on here.  And they didn't even do it during baseball season.  I'll also say that 36 hours is not nearly enough time to visit all of the great places to eat in town.  But they do mention some of my favorites.

Two articles about urban homogenization

11/29/2012

 
Two pieces have just been published about our Urban Homogenization work. The first, by science reporter Maggie Koerth-Baker, provides a layperson's overview of the urban homogenization hypothesis and some of the patterns that initially motivated our proposal.  It will be published on Sunday in the New York Times magazine, and is online here.  The second piece is an article written by Laura Ogden, an anthropologist and one of our collaborators on the project.  Laura's piece addresses the peculiar social and ecological geography of south Florida, and the differences between front yards and back yards.  The article was written for Miami Rail, a local alternative newspaper, but you can read it on the Art Practical website here.

    Welcome!
