Abstract

Geological history of marine phosphate Phosphorus is generally thought to be a limiting nutrient of primary productivity in the oceans, and is important in regulating the redox state of the ocean–atmosphere system. Planavsky et al. use the ratio of phosphorus to iron in iron-oxide-rich sedimentary rocks through time to evaluate the evolution of the marine phosphate reservoir. They find relatively constant phosphate concentrations during the past 542 million years of Earth's history. The data are also indicative of high dissolved phosphate concentrations in the aftermath of the 'snowball Earth' glaciations around 700 million years ago, which could have led to high rates of primary productivity, organic carbon burial and an increase in atmospheric oxygen levels, paving the way for the rise of metazoan life.
