• Anions/cations: Cl, SO4, Ca, K, Na, and Mg
• Physical variables: temperature, pH, conductivity, 
• Discharge: continuous discharge records from D. Genereux, North Carolina State University. 
• Frequency: weekly
• Period: since 2001.

Ecological data

• As part of specific ecological studies, we had been collecting data on a variety of ecosystem processes, such as leaf litter decomposition, microbial respiration, and invertebrate and fish diversity. 
• Our ecological data can be found in our community in Zenodo.org.  Recent data is available upon request.

Long-term data repository

• Our stream chemistry data is deposited in the databases of the Luquillo LTER program in Puerto Rico for long-term storage and access.
• Our ecological data, meeting presentations, and student theses are deposited in Zenodo.org.
• Copies of publications, recent data, and data that are in the process of publication is available upon request. Please contact us for further information (alonso.ramirez at ncsu.edu).
