sediment coring

Sediment coring is a method used by scientists to collect samples of sediment layers from the bottom of oceans, lakes, or rivers. A corer is a long tube that is inserted into the sediment to extract a cylindrical sample, capturing layers of soil, organic matter, and microorganisms. By analyzing these samples, researchers can learn about past environmental conditions, climate changes, and ecological histories over time. This information helps us understand how ecosystems have evolved and predict future changes, making sediment coring an important tool in environmental science and climate research.
