Sediment sampling techniques

Sediment sampling techniques are methods used to collect soil or mud from the bottom of rivers, lakes, or oceans for analysis. Common techniques include grab sampling, where a device scoops up sediment from the surface, and core sampling, which extracts a cylindrical section of sediment to study layers over time. Scientists may use these samples to understand pollution levels, track ecosystem changes, and assess geological history. The collected sediments are analyzed in labs for various properties, such as composition and contaminants, providing valuable insights into environmental health and changes.
