marine sediment cores

Marine sediment cores are cylindrical samples taken from the ocean floor, which capture layers of sediments deposited over time. By drilling into these layers, scientists can analyze the Earth's history, including climate changes, ocean conditions, and biological activity. Each layer represents a specific period, preserving fossils, organic materials, and chemical signatures. Studying these cores helps researchers understand past environments, how they have changed, and predict future trends, providing valuable insights into climate change, ecosystem health, and Earth's geological processes.
