34 ka B.P. was similar to the timing of one’s Mono Lake travels (22), suggesting this particular journey is in charge of the new ?14C peak (Fig. 3).
The newest wider reduction in ?14C during the it interval **you will plausibly come from increasingly broadening ocean venting. **Virtually any products becoming equivalent, the brand new smaller the new collection date, the fresh new less time for 14C in order to decay, the greater 14C inside the deep seas and you will, from the mass balance, the lower this new ?14C of your own conditions. Presuming the typical deep water ages of one thousand years within eleven ka B.P. and you will a good sixty:1 proportion out-of deep-water so you’re able to atmospheric carbon, new decrease in atmospheric ?14C more now several months would be informed me of the a progressive change for the deep water age from around 3000 ages within twenty five ka B.P.
