Mid holocene

Abstract

Broadly speaking, reef accretion in both the Indo-Pacific and Caribbean regions is dominated by ice-sheet-meltdriven sea-level changes through the Holocene. Differences in reef morphology between the two regions, including the amount of framework coral and the extent of reef flats, reflect relatively small-scale variations in regional RSL, which occurred since the mid Holocene. These differences are due to long-lived global-scale isostatic processes which cause sea-floor subsidence (RSL rise) in some regions and RSL fall in others since the mid Holocene.
