Soil core from coastal wetland

Detailed Description

Scientists collect soil cores in coastal wetland by removing a section of peat, the organic-rich material that makes up salt marshes. After the soil is removed, water quickly fills in the void. This water-logged environment underground is devoid of oxygen and is an important reason that salt marsh peat preserves a record of historical changes. Soil cores are an important research tool for discovering how management changes, such as tidal restoration in salt marshes, have made long-term impacts on coastal wetland resilience.
