Dataset - Postglacial Relative Sea Level Change in the Caribbean and Pacific coasts of Colombia: Numerical Modeling and Sea Level Indicators

Published: 28 November 2022| Version 1 | DOI: 10.17632/7nhpbhvfnz.1


We provide simulations of the postglacial relative sea-level (RSL) change along Colombia's Caribbean and Pacific coasts in the Northern Andes. We used SELEN4 to model RSL change from GIA processes from -26 ka to the present with a resolution of 500 yrs. We include a compilation of sea-level indicators available from the literature.

1. SELEN4 MODELING (Spada & Melini, 2019): We used modified versions of the Green functions (surface and rotational) and the polar motion transfer function to account for our VM5 models.

RADIOCARBON CALIBRATION (Lougheed & Obrochta, 2016): We used the Matlab script 'PaniEtAl_RadiocarbonCal.m' and MS Excel files (e.g., 'MartinezEtAl_2010_Table2.xlsx') to calibrate radiocarbon dates. The naming of resulting calibration figures -PNG files- is: JB2000 (Jaramillo & Bayona, 2000) M2010 (Martínez et al., 2010) P1982 (Page, 1982) PJ1981 (Page & James, 1981) U2013 (Urrego et al., 2013) V2014 (Vélez et al., 2014) 3.
