Data Catalog

Each Cedar Creek research project is assigned an “experiment number”, such as “e001”. The data from each research project is indexed under that project’s experiment number. Cedar Creek research is grouped into two categories. Core LTER Data is data generated though research funded by LTER and is provided in accordance with the LTER Network Data Access Policy. Other Cedar Creek data is generated through many different funding sources, We strive to provide access to data from research not funded through LTER using the same LTER policy guidelines, but due to the historical nature of much of this data, we cannot guarantee these data are complete. All data may be searched for by experiment number, core area of research, keyword, and/or investigator. Use of data must be in accordance with the conditions agreed to in the Cedar Creek Ecosystem Science Reserve Data Access Policy.
