Arctic LTER long-term datasets include monitoring data and data from whole ecosystem manipulations in tundra, lakes, and streams. 

All datasets are archived at the Environmental Data Initiative (EDI) while most collaborating project datasets are archived at the NSF Arctic Data Center (ADC) as required by their project's data plan.  To find these data there are several search portals:

• Toolik Field Station's DataOne data portal.  (Including Arctic LTER datasets in EDI and ADC data portals).
• Customized catalog of Arctic LTER datasets in EDI.
• EDI Data Search See EDI's Finding Data for help on searching. Tip: use the Advanced Search, select Arctic LTER from the Sites tab, and choose parameters from the other tabs.
• Arctic Data Center Search
• DataONE Data Search
• Google Data Search
