10 Be in Arctic Ocean sediments
The 10 Be deposition rate in two Arctic Ocean cores, ~80°N, was measured to be ≤0.6 atoms cm -2 sec -1 , much less than the 10 Be deposition rate reported for other oceanic regions. Possible causes for the low10Be deposition in the Arctic are: (1) latitudinal variation in the10Be delivery rate from...

Summary: | The 10 Be deposition rate in two Arctic Ocean cores, ~80°N, was measured to be ≤0.6 atoms cm -2 sec -1 , much less than the 10 Be deposition rate reported for other oceanic regions. Possible causes for the low10Be deposition in the Arctic are: (1) latitudinal variation in the10Be delivery rate from the stratosphere; (2) the presence of an ice cover on the Arctic, which may inhibit the transfer of atmospherically supplied10Be from sea surface to sediments; and (3) locally low scavenging efficiency of sedimentary particles for 10 Be in the Arctic. |
