Imprints: Sifting through microfossils with Rajani Panchang Everything Environment by Mongabay India

Looking at sediment under a microscope is a window into past environments and climates. In a dot of sediment, you may find thousands of microfossils - tiny remains of bacteria, protists, fungi, animals, and plants.
Rajani Panchang, an oceanographer and micropaleontologist, uses microfossils from oceans, of tiny marine organisms, to interpret how the climate and environment may have been when they were alive. Such work gives us ideas about the chemistry and temperature of the ocean, ocean currents and wind patterns of the past.
Paleoclimate research eventually feeds into reports that give us the large picture of climate change and our means of recovery. It starts with studying sediments.
