Dear Colleague: The Denitrification Research Coordination Network (http://denitrification.org) is pleased to announce a workshop entitled "Denitrification in Managed Ecosystems" to be held May 12-14, 2009, at the University of Rhode Island Bay Campus, Narragansett, RI (nearest airport is Providence, RI). Denitrification is an important tool in managed ecosystems (e.g., artificial wetlands, riparian buffers, wastewater treatment facilities or holding ponds, etc.) designed to enhance removal of nitrogen or minimize export

I have started work on major revisions to the czen.org website. These revisions will make czen.org easier to use and improve functionality. However, while these changes are being made you might encounter odd behavior and strange functionality on the site. I am making every effort to limit the disruption during peak traffic hours, but I want to let you know what is going on just in case you experience any trouble. Feel free to contact me if you have any questions or if you have suggestions for site improvements.

A fundamental goal of CZEN is to encourage and promote interdisciplinary research among a network of sites, people and data that span environmental gradients. Until recently the fledgling network has worked to establish the most promising sites with only an eye toward the final goal. But recent awards by the National Science Foundation to support Critical Zone science proposals provide an important step in more quickly building the network. Researchers in the U.S. are encouraged to write proposals to pursue research that crosses the sites within CZEN.

Critical Zone Ontology, CZEN , (2008)

To Critical Zone scientists attending Goldschmidt in Vancouver: On Wednesday afternoon, July 16th at 2:30PM at the Goldschmidt meeting in Vancouver, we are planning a small meeting on the UBC Campus. The building and room location for this meeting is Irving K Barber Learning Center- Room 260. Because this is a public meeting, we encourage all interested in the growth of Critical Zone science to attend.
