Goal: Phython code developed calibrated radiocarbon ages in surface marine sediments. The ages can be corrected using regional marine surface reservoir ages expressed as R (R = 14C from the ocean - 14C from the atmosphere), which represents the deviation from the SHCal20 curve at a given time, using the python library iosacal 0.6.0 (Costa et al., 2022, https://pypi.org/project/iosacal/). All calibrated ages are reported as years Before Present (BP, considering present the year 1950). We considered foraminifera with radiocarbon ages >1950 (Post-radiocarbon boom period) or samples with radiocarbon ages smaller than the average of the different regional modern reservoir ages calculated for as specific region as recent.

Imputs:
- raw 14C ages with errors
- SHCal20 Southern Hemisphere Calibration, 0–55,000 Years cal BP (Hogg et al., 2020) https://www.cambridge.org/core/journals/radiocarbon/article/shcal20-southern-hemisphere-calibration-055000-years-cal-bp/2C20CF55E1251FD2822B009EB795C080
- regional marine surface reservoir ages expressed as R
Necesary libraries to be imported to run the code:
- pandas
- numpy
- python library iosacal 0.6.0 (Costa et al., 2022, https://pypi.org/project/iosacal/)
