A new relative sea level curve for the Robeson Channel area contrasts with previously published curves for the area by inferring that rapid emergence may have commenced at ca. 7400 BP, as much as 1200 yr earlier than previously predicted. Subsequently, uplift may have occurred at much lower rates from ca. 6000 BP to present. A comparison of shell dates used for the relative sea level curve and dates on disseminated total organic carbon (TOC) fractiop from lacustrine and marine sediments from sediment cores from emerged coastal lakes shows wide discrepancies. Furthermore, several inifmite TOC dates (>27,7SO to >40,600 BP) from glaciomarine sediments may imply that the region was ice-free during the last glacial maximum, but the validity of the TOC dates from the sediment cores is questionable due to variable contamination with redeposited detrital organic matter.
