The total deposition fluxes of 210 Pb and 7 Be were determined at New Haven, Connecticut, and Bermuda over approximately the same annual period in 1977–1978. The 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 2 /y. The 210 Pb flux at Bermuda is 0.69 dpm/cm 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 7 Be fluxes at New Haven and Bermuda are 22.7 and 17.1 dpm/cm 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.

Pleistocene Sea Levels from Raised Coral Reefs of Haiti

The elevations and ages of a sequence of three uplifted Pleistocene coral reefs on the Northwest Peninsula of Haiti have been determined. With the assignment of a sea level of +6 meters (relative to the present day) at 130,000 years before present and constant uplift of the reefs, the data indicate that sea level stood -10 and -13 meters at 108,000 and 81,000 years before present, respectively. These results are in substantial agreement with those reported for Barbados and New Guinea and support the hypothesis of constant uplift for each area. Sea level data from raised reefs indicate that the interglacial marine oxygen isotope oscillations during oxygen isotope stage 5 are a result of 30 percent ice volume effects and 70 percent temperature effects.
