	abstract = {Reconstructions of atmospheric Delta(14)C for the deglacial period reveal a 190 +/- 10\%. drop between 17.5 and 14.5 kyr before present, during the {\textquoteright}mystery interval{\textquoteright}. While it appears that the major contributor must be the mixing between an isolated low radiocarbon abyssal reservoir and the remainder of the ocean, a combination of (14)C measurements on coexisting benthic and planktic foraminifera shells and (13)C/(12)C measurements on benthic foraminifera make it difficult to identify a sufficiently large volume for this reservoir. An alternative scenario, based on higher (14)C production rates between about 38 and 18 kyr ago, would escape the need for a large, isolated reservoir prior to the mystery interval but instead would call for a better ventilated ocean afterwards. The addition of (14) C-deficient sedimentary carbon appears not to be an important contributor. While the unlikely explanation that the half-life of (14)C is 15\% greater than the accepted value (5730 yr) would eliminate the steady decrease in the (14)C/C over the last 40 kyr, it would not explain the steep drop which occurred between 17.5 and 14.5 kyr.
