The total deposition fluxes of /sup 210/Pb and /sup 7/Be were determined at New Haven, Connecticut, and Bermuda over approximately the same annual period in 1977-1978. The /sup 210/Pb flux has remained virtually constant at New Haven from 1973 to 1978, the flux in the 1977--1978 period being 1.2 dpm/cm/sup 2//y. The /sup 210/Pb flux at Bermuda is 0.69 dpm/cm/sup 2//y. This lower flux than expected from model calculations is due to the establishment of a blocking high pressure cell during the summer which deflects continental air. The /sup 7/Be fluxes at New Haven and Bermuda are 22.7 and 17.1 dpm/cm/sup 2//y, values consistent with western North Atlantic oceanic standing crop measurements, but higher than some other estimates. Where the difference cannot be attributed to differences in sampling it is ascribable to regional differences compatible with the oceanic data.
