Abstract

Read online

What caused the end of the high ocean productivity in the tropics in late Miocene-early Pliocene is debated. Here, deep-sea sediment records reveal that productivity abruptly declined 4.6 million years ago, potentially linked to reduced seasonality and monsoon intensity that led to decreased nutrient supply to the oceans.
