Mapping the abundance of 13C in leaf-wax components in surface sediments recovered from the seafloor off northwest Africa (0–35°N) reveals a clear pattern of delta13C distribution, indicating systematic changes in the proportions of terrestrial C3 and C4 plant input. At 20°N latitude, we find that i...
