Dissolved inorganic radiocarbon in the North Pacific Ocean and Sargasso Sea
We present radiocarbon measurements of dissolved inorganic carbon (DIC) in depth profiles from reoccupations of our central North Pacific Ocean and Sargasso Sea (SS) sites. From 1985 to 1999, an increase in Delta C-14 values of 6-17 parts per thousand was measured between 1150 and 2400m depth in the...
