Before publishing some tidying up is need, especially the units used for time need attention:

In the text you are using ‘ka’, ‘ka PB’, ‘yr’, ‘year’, ‘years’, and in the figures ‘Year (ka BP)’ as axes label, and ‘ka’ as well as ‘ka BP’ and ‘ka years’ within the figures.

Please be consistent throughout, us ‘a’ [annum] as unit for time and ‘ka’ where appropriate. Please refrain from using ‘BP’. This should be reserved for uncalibrated (and thus wrong) radiocarbon years. Please replace ‘year’ as axes label with ‘age’.

Figure 1; Figure caption b): replace ‘vegetation’ with ‘land use’; ‘in the study region’ is needed only once
Figure 2; Figure caption: Reword – you show the relative sea level not its variation
Figure 3: change ‘radical lines’ to ‘radial lines’

In Figure 8 please plot data points only and do not connect points with a line. Reword the figure caption: you do not show a comparison – you just show 4 different graphs next to each other
