Images from multiple satellites are used to support the BRomine, Ozone, and Mercury EXperiment (BROMEX) in Barrow during March 2012.  Launched by NASA and other international space agencies, these satellites can observe the Earth’s environment including sea ice.  Here, we present two demonstrations on how to use satellite images: (1) to identify leads in sea ice that is useful for whaling activities, and (2) to detect multi-year sea ice that has low salt content (drinkable water when melted).  For lead identification, we can use images from the NASA Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra and Aqua satellites.  We show how to download MODIS images in Google Earth kmz format from the BROMEX website to identify leads in sea ice and measure their distances to certain locations near Barrow.  For multi-year sea ice detection, we can use synthetic aperture radar (SAR) images from the Canadian RADARSAT-2 satellite or the European Envisat satellite.
