PNRA (Paleoceanographic Data from the North Atlantic Region)

PNRA (Paleoceanographic Data from the North Atlantic Region) involves studying ancient ocean conditions in the North Atlantic by analyzing natural recorders like sediment cores and fossilized microorganisms. These data help scientists understand past climate changes, ocean currents, and environmental shifts over thousands to millions of years. By examining chemical compositions, microfossils, and sediment layers, researchers reconstruct how the ocean and climate have evolved, providing insights into future climate trends and the impacts of natural variability on Earth's systems.
