Cross-CZO Studies

A major goal of the LCZO is to promote synthesis within the geosciences and between the various institutions and students involved with the project.  While the focus and study areas of the LCZO are distinct to that of the Luquillo LTER and Puerto Rico NEON site, there are ample opportunities to collaborate with those groups.  Likewise, LCZO members have collaborations with the many  CZOs and various LTER sites in the study of carbon dynamics and quality (Plante, Silver, McDowell, Stroud Water Resource Center and others) and with the coastal site Delaware (Horton) as well as with an investigation of granite weathering with C. Rasmussen (Arizona CZO).

Cross-CZO Studies use LCZO as an "End Member"

Because the Luquillo CZO is located in a tropical montane environment it is an “end-member” system with respect to temperature, rainfall, chemical and physical erosion.  Therefore a major goal of the Luquillo CZO is to promote and foster cross-site research and exchange.  These activities are not limited to the CZO network but also include the NSF-supported LTER Network, the USFS- Experimental Forests, NSF-NEON, and more specialized networks like Cloudnet (www.ccc).  Current cross-site studies include investigations of deep critical zone structure using bore-holes and geophysics, use of isotopic tracers, testing soil-oxygen sensors and cloud mist collectors.
