Project Description

DRI investigates the fate of mercury on snow in polar (Summit Station, Greenland) and alpine areas (Niwot Ridge, Rocky Mountains). The goal of this research is to evaluate how both perennial snow surfaces (e.g., Greenland/Antarctica ice sheet: ~14 million km2 surface) and seasonal snowpacks (e.g., in the Rocky Mountains, Sierra Nevada) interact with the lower atmosphere (i.e., deposition and emission processes) and affect Hg inputs to ecosystems via snowmelt.

Summit is a year round station located in the middle of the Greenlandic ice sheet.

 Summit Research Station to continuously monitor snow air chemical composition up to 2 meters depth. Research Station on Niwot Ridge in the Rocky Mountains.
