Abstract
The variation of cosmic ray intensity and the sedimentation rates in the past can be determined under either of the following conditions: If the titanium deposition, in addition to being uniform in space, has remained constant in the past, then the titarium concentrations yield the sedimentation rate and therefore the age of the various sediment layers. The Be10 concentrations then determine the cosmic ray intensities at various ages. If the cosmic ray intensity has varied linearly with time, the total Be10 contents of a long core together with the present day deposition rate of Be10, yields the cosmic ray intensity as a function of time. Be10 concentrations at any particular depth then determine the sedimentation rate and the rate of deposition of titanium. The results of these two methods are presented.
