| description | Ocean sediments give information on the paleoclimatic evolution in the geological past which gives
detailed information on both the age of the sediments and both paleoceanographic and paleoclimatic
conditions during sedimentation. One possible way to date sediments is with 210Pb method which
can be used to date sediments up to 100 years. In this study, two core samples labelled as JB15 and
JB17 were collected using pledging corer, analysed and measured for the activity of 209Po and 210Po
using the alpha spectrometer. Applying the methods, average sedimentation rates for JB15 and JB17
were calculated as 0.38 cmyr-1 and 0.43 cmyr-1, respectively. Assuming that the sedimentation rate
values are accurate, this might imply that the sediments at the depth of 30 cm were deposited 70
years ago. |
