Figure F2. Subsidence estimates for North Atlantic DSDP records with an interpretation of the carbonate compensation depth (CCD) history from Tucholke and Voigt (1984). Red dashed lines report the calculated subsidence history of the base of J-Anomaly Ridge, DSDP Site 384 on the crest of J-Anomaly Ridge, and the tops of the Southeast Newfoundland Ridge (SENR) seamounts. In contrast to this CCD reconstruction, our seismic data suggest that carbonate sediments extend nearly to the base of J-Anomaly Ridge during the Paleogene (yellow area), see Figure F1.
