Project Description

(a) Mercury measurements for the Bromine, Ozone, and Mercury Experiment (BROMEX) to be carried out in March 2012: Deployment and operation of Out-On-The-Ice system (OOTI) to measure fully speciated atmospheric mercury (i.e., GEM, GOM, and PHg) concentrations, along with ozone and site meteorology over the sea ice. Operation of the speciation system at an inland site Deployment of OOTI/DRI's Mercury Gradient system for the measurement of GEM gradients (4 heights) to quantify surface exchange fluxes of mercury over the sea ice.
