Figure F35. Carbonate, total organic carbon (TOC), and total nitrogen (TN) depth profiles at Southeast Newfoundland Ridge Sites U1407–U1410. Organic matter increases substantially around the middle/late Eocene boundary (yellow shading), whereas carbonate content decreases in the same interval. PETM = Paleocene/Eocene Thermal Maximum, OAE 2 = Oceanic Anoxic Event 2. The numbers next to OAE 2 indicate maximum identified TOC and TN values (out of scale).
