Atmospheric Deposition Monitoring
Voyageurs NP has a NADP/NTN wet deposition monitoring station in the park since 2000 (site #MN32 (Sullivan Bay)) and a CASTNet dry deposition monitoring site since 1996 (site #VOY413). Trend data are not yet available from these sites. However, data has been collected at the NADP/NTN site at Fernberg, Minnesota (site #MN18 (Snowbank Lake)), approximately 50 miles southeast of Voyageurs NP, since 1980.
