During the winter and spring seasons of 1989 and 1990, we collected samples of the background aerosol at Wrangel Island in the eastern Soviet Arctic. The samples were analyzed by optical transmission to determine the concentration of aerosol ``black`` carbon (BC), with results ranging from 5 to 167 nanograms per standard cubic meter. These results are compared with the continuous measurements at the NOAA/CMDL monitoring station at Barrow, Alaska for cases when meteorological trajectories connected the two locations with transit times of from one to two days. The preliminary results suggest that concentrations of aerosol BC are reduced at Wrangel relative to Barrow.
