Strontium dating of foraminifera, shells & corals

Strontium dating (as enabled by the 87Sr/86Sr ratio of marine carbonates) can be used to date various marine samples based on the premise that the mixing of oceanic strontium occurs relatively rapidly through time compared to the residence time of oceanic strontium. This creates a uniform global marine 87Sr/86Sr ratio at a given point in time; the fluctuations over millions of years represent a ...

How do humans impact cyanobacteria thousand years ago?

We often look at how algae affect humans. Whether by analyzing how toxic blooms harms us or by looking at the health benefits of including edible ones in our diets, countless areas benefit from a ...
