| Summary: | <p>Coastal subsidence owing to compaction of Holocene strata and deeper-rooted
components affects large delta plains such as the Tabasco delta in southern
Mexico (Gulf coast). For this system, GNSS3-PPP ground-truthed LiDAR imagery
of high-resolution dated beach-ridge series reveals considerable
differential subsidence on either side of the present Usumacinta-Grijalva
River mouth. Collected field-data allows for quantification of differential
subsidence over several time windows and reconstruction of relative
sea-level rise back to 5000 years ago. Observed differential subsidence of
1–1.5 m is regarded to be syn-sedimentary delta-subsurface compaction of
buried strata in response to the accumulating overburden of the prograding
beach-ridge complex.</p> |
