Relative sea level chronology determined from raised marine sediments and coastal isolation basins, northeastern Ellesmere Island, Arctic Canada

A new relative sea level curve for the Robeson Channel area constrasts with previously published curves for the area by inferring that rapid emergence may have commenced at c7400 BP, as much as 1200yr earlier than previously predicted. Subsequently, uplift may have occurred at much lower rates from...

Description
Summary:A new relative sea level curve for the Robeson Channel area constrasts with previously published curves for the area by inferring that rapid emergence may have commenced at c7400 BP, as much as 1200yr earlier than previously predicted. Subsequently, uplift may have occurred at much lower rates from c6000 BP to present. A comparison of shell dates used for the relative sea level curve and dates on disseminated total organic carbon (TOC) fraction from lacustrine and marine sediments from sediment cores from emerged coastal lakes shows wide discrepancies.
