Rapid sea-level changes at the close of the last interglacial (substage 5e) recorded in Bahamian island geology: comments and reply
Article Abstract:
A.C. Neumann and P.J. Hearty have provided evidence in the Bahamian geologic record for rapid sea-level change at the end of the last interglacial. The major issue of their work is that sea level was at approximately +2 m for most of the 5e highstand, but that is rapidly increased to +6 m briefly at the end of that highstand and then dropped rapidly shortly thereafter. However, their article had several inconsistencies, extreme estimates of erosion rates and unlikely models to support a rapid increase and drop in sea level at the end of substage 5e.

Continuous record of reef growth over the past 14 k.y. on the mid-Pacific island of Tahiti: comment
Article Abstract:
The authors of 'Continuous record of reef growth over the past 14 k.y. on the mid-Pacific island of Tahiti' base their hypothesis of the age and elevation of drowned breakwater coral reefs in the Indo-Pacific on the establishment of a link between a coral algae community in Tahiti and sea level and statistics from a companion study. The accuracy of using that coral-algae community to determine sea level is questioned and inconsistencies in the data that affect accuracy of sea level interpretation are discussed.

Return of the coral reef hypothesis; basin to shelf partitioning of CaCO3 and its effect on atmospheric CO2: comment and reply
Article Abstract:
A comment and reply on the theory describing basin to shelf partitioning of CaCO3 and its effect on atmospheric carbon dioxide is presented. The comment presents an alternative explanation to the reaction of carbonate platforms or coral reefs to sea-level change. A comparison of CaCO3 dissolution after the emergence of coral reefs and CaCO3 deposition during their submersion provided data that approximates that found in the model that uses the combination of deep and shallow water CaCO3 activity.
