Figure F35. Downhole profiles of carbonate, total organic carbon (TOC), and total nitrogen (TN) from Southeast Newfoundland Ridge Sites U1407–U1410. A common feature is that organic matter increases substantially around the middle/late Eocene boundary (yellow shading), whereas carbonate content decreased simultaneously. PETM = Paleocene/Eocene Thermal Maximum, OAE 2 = oceanic anoxic Event 2. The numbers next to OAE 2 indicate maximum TOC and TN values identified (out of scale).
