Welcome to the Luquillo CZO Data Repository

Welcome to the Luquillo CZO data repository. Here you can find out about ongoing research in the CZO and find data related to these projects. If you have any questions about how to use the site or any other general questions please contact lczo-help@sas.upenn.edu

CZO datasets are a powerful resource for developing and testing Earth system models. CZOs produce a large volume of data from a wide range of physical, chemical, and biological disciplines as well as spatial and temporal scales. This "flood" of disparate observational data partly reflects a new generation of integrated measurements. For example, most CZOs are using LIDAR imagery, copious isotopic samples, and low-cost sensors; others are also using eddy correlation and embedded sensor networks.

About the Luquillo CZO:

The Luquillo Critical Zone Observatory (LCZO) is located in Luquillo Mountains of northeastern Puerto Rico. The multi-disciplinary team of geoscientists working at the site are addressing a set of specific hypotheses that are related to the following overarching questions: How do critical zone processes and the flow and transformations of material differ in landscapes with contrasting bedrock but similar climates, land use, and geologic histories? What are the implications of these differences for the long term sustainability of water and soil resources?

Specifically, the observatory is quantifying and comparing critical zone (CZ) processes in landforms and watersheds underlain by three different rock types, granodiorites, volcaniclastics, and their associated contact metamorphic rocks. Previous research has demonstrated that these are some of the most rapidly eroding watersheds in the world. There are also dramatic, but poorly quantified, contrasts in CZ processes between areas underlain by these bedrocks. Individual research project include studies of deep weathering, soil formation and soil carbon accumulation, riparian zone dynamics, fluvial geomorphology, and meteorology. Infrastructure includes weather stations, instrumented soil pits and riparian zones, and stream flow gages.

The principal researchers and students involve in the Luquillo Critical Zone Observatory are from the UPENN, the Pennsylvania State University, the University of California at Berkeley, the University of New Hampshire, the University of Puerto Rico, the US Geological Survey, and the US Forest Service International Institute of Tropical Forestry. The Observatory will also provide facilities for collaborators from a host of US and International Universities and Research Centers.

The following acknowledgment should accompany any publication or citation of these data:

Logistical support and/or data were provided by the NSF-supported Luquillo Critical Zone Observatory (EAR-0722476) with additional support provided by the USGS Luquillo WEBB program and the USDA Forest Service International Institute of Tropical Forestry.

The user of Luquillo CZO data agrees to provide proper acknowledgment with each usage of the data. Citation of the name(s) of the investigator(s) responsible for the data set, in addition to the generic statement above, constitute proper acknowledgment. Author(s) (including Luquillo CZO investigators) of published material that makes use of previously unpublished Luquillo CZO data agree to provide the Luquillo CZO data manager with four (4) copies (preferably reprints) of that material for binding as soon as it becomes available. The user of Luquillo CZO data agrees not to resell or redistribute shared data. The user of these data should be aware that, while efforts have been taken to ensure that these data are of the highest quality, there is no guarantee of perfection for the data contained herein and the possibility of errors exists.
