The Howland Integrated Forest Study (HIFS) is the location of numerous current and past studies dealing with the interactions between our chemical and physical climate, and forested ecosystems. This image shows a tower above the forest canopy that facilitates this research, and located near this tower is the site of studies dealing with climate change, biogeochemical cycling, and atmospheric deposition of nitrogen, sulfur, and other pollutants.   This site is under construction at this time.

There have been a number of research projects past and ongoing at the HIFS site.  Future modifications of this site will add additional information.  Here are a few links of potential interest. From the biogeochemical cycling plots: -Bar graph of precipitation (PPT), throughfall (TF), Oa horizon (Oa) and Bs horizon (Bs) soil solution composition. - Precipitation and Oa and Bs horizon SO4, NO3 and Cl time series. From other programs with work at Howland: the Howland Ecosystem Research web site NASA's Forest Ecosystem Dynamics Project The AmeriFlux program The Clean Air Status and Trends Network Maine DEP Ozone Monitoring Woods Hole Research Center Howland Program In the future, we will be posting data from the soil warming plots and related activities (see the GCTE site for a  CROSS BIOME SYNTHESIS OF ECOSYSTEM RESPONSE TO GLOBAL WARMING), including the Maine Gradient Study (MEGS) and other environmental work at this site.
