Objective: Understand and assess the impact of Arctic sea ice reduction on bromine explosion, ozone depletion, and mercury deposition in the Arctic environment.

• Satellites: OMI, GOME-2, SCIAMACHY, MODIS (Aqua/Terra), OLS, Oceansat-2, SSMIS, SMOS, TanDEM-X, Envisat ASAR, RADARSAT-2
  - Data used to target the surface and airborne assets
• Surface Components:
  - Icelanders (chemistry bouys) and SCPs (meteorological buoys) in the Chukchi Sea and Beaufort Sea; wind velocity, temperature, radiation
  - Tundra Site: Full mercury speciation, bromine/chloride/ozone suite, radiation tower, weather station, and snow tower

• Airborne Components:
  - Purdue Airborne Laboratory for Atmospheric Research (ALAR) Aircraft, measuring volatile organic compounds (VOCs) fluxes, vertical profiles
  - NASA P3 - flights coordinated with IceBridge; data collected for BROMEX over Barrow, AK

• Several bromine explosions and ozone depletion events have occured already, which have been measured by BROMEX
• Principal Investigator: Son Nghiem - Jet Propulsion Laboratory
• Co-Investigators: Matthew Sturm, Thomas Douglas, and Don Perovich - CRREL, Paul Shepson - Purdue University, William Simpson - University of Alaska, Ignatius Rigor - University of Washington
