“…In South Africa, Compton [44] studied Langebaan Lagoon, a salt-marsh lagoon on the southwest coast to produce a 9000-year Holocene RSL record, which is in general agreement with a previous study of beach rock by Ramsay [149]. In Langebaan Lagoon, RSL rose in the early Holocene at a rate of 4.2±0.8 m/ka between 9 and 6 ka (Figs.…”

Holocene relative sea-level (RSL) records exhibit spatial and temporal variability that arises mainly from the interaction of eustatic (land ice volume and thermal expansion) and isostatic (glacio-and hydro-) factors. We fit RSL histories from near-, intermediate-, and far-field locations with noisy-input Gaussian process models to assess rates of RSL change. Records from near-field regions (e.g., Antarctica, Greenland, Canada, Sweden, and Scotland) reveal a complex pattern of RSL fall from a maximum marine limit due to the net effect of eustatic sea-level rise and glacio-isostatic uplift with rates of RSL fall as great as −69±9 m/ka. Intermediatefield regions (e.g., mid-Atlantic and Pacific coasts of the USA, Netherlands, Southern France, St. Croix) display variable rates of RSL rise from the cumulative effect of eustatic and isostatic factors. Fast rates of RSL rise (up to 10±1 m/ka) are found in the early Holocene in regions near the center of forebulge collapse. Far-field RSL records exhibit a midHolocene highstand, the timing (between 8 and 4 ka) and magnitude (between <1 and 6 m) of which varies among South America, Africa, Asia, and Oceania regions.

“…Ramsay and Cooper (2002) described the Late Quaternary sea5 level changes for a 180km stretch of coastline in eastern South Africa. Although not without problems, e.g., use of wood fragments as index rather than limiting points and combination of uncalibrated radiocarbon chronologies with those of uranium series, evidence from South Africa broadly corresponds to the records from the Caribbean (Ramsay, 1995;Illenberger, 1996;Ramsay and Cooper, 2002).…”

“…The Southern Hemisphere exhibits well-docu -mented, higher-than-present Holocene sea-level events, as can be found in South Africa (e.g., Miller et al 1993, Ramsay 1995, Australia (e.g., Belperio 1995, Baker andHaworth 2000), and South America (Porter and Stuiver 1984, Isla 1989, Cavalotto et al 2004. and Suguio (1993) have presented several sea-level curves for the Brazilian coast based on more than 700 radiocarbon dates.…”

The present paper aims to investigate the relative sea-level and the coastal evolution during the Holocene in the Rio de Janeiro coastline, based on geological and biological indicators. Using topographic survey, excavation and coring, and 14 C dating of these coastal deposits and beachrocks outcrops, we have reconstructed a sealevel curve for the Holocene. For the first time on the Brazilian coast it was identified a negative record of relative sea-level during Late Pleistocene and Early Holocene transition. After the transition, a relatively rapid increase of sea-level began. At approximately at 8500 cal yr BP, the sea-level was 0.5 m below the current level, was overtaken for the first time in the Holocene, at approximately 7500 cal yr BP. The maximum level of +2.5 m was reached between 4770 and 4490 cal yr BP. At the point of maximum transgression, the sealevel began a general behavior of lowering until the present. These results confirm other data already obtained elsewhere along the Atlantic coast of South America. The results of this study are consistent with previous researches and they help to refine the Holocene sea-level record along the Brazilian coast.
