Mid-Pacific microatolls record sea-level stability over the past 5000 yr
There has been geographical variation in sea level since rapid postglacial melting of polar ice ceased ~6 k.y. ago, reflecting isostatic adjustments of Earth and ocean surfaces to past (and ongoing) redistribution of ice and water loads. A new data set of over 100 fossil microatolls from Christmas (Kiritimati) Island provides a Holocene sea-level record of unparalleled continuity. Living reef-flat corals grow up to a low-tide level. Adjacent fossil microatolls, long-lived Porites corals up to...[Show more]
