# A study of selected ecosystem parameters potentially sensitive to air pollutants in the Olympic Peninsula, 1984-1987 ## Dataset - **Database Code:** TL003 - **Title:** A study of selected ecosystem parameters potentially sensitive to air pollutants in the Olympic Peninsula, 1984-1987 - **Abstract:** To establish rates of ecosystem processes in a near pollutant free environment and measure yearly patterns of variability of these processes. The methodologies used in this study range from standard to untested designs. All procedures are being tested and scrutinized. Our goal is to make suggestions about the kinds of processes and procedures to measure and use for accurate baseline data collection. Leaf, needle, and branch decay is measured to determine the annual decay. Canopy litter input is collected and measured at monthly intervals. Determine patterns and rate of this fine litter input. Determine components of input, i.e. proportion needles cones, bark, fine branches, etc. Subproject is a study of ecosystem processes potentially sensitive to airborne pollutants. This study provides baseline data and measurement of natural variability in ecosystem functioning and productivity in a pristine area. - **Keywords:** decay rates; litterbags; decomposition; litter decomposition; biological processes; litterfall; primary production; atmospheric deposition; inorganic nutrients; litter; organic matter; acid rain; ecosystems; Long-Term Ecological Research (LTER); natural variability; ecosystem processes; primary production; inorganic nutrients; organic matter - **Temporal coverage:** 1984-06-19 to 1987-01-01 - **Principal Investigator:** Mark E.
