GPR and Coring of Lake Sediments

Student: Jianguang Chen Co-investigator: Elliott Burden

GPR surveying of a km-scale post-glacial lake over a gold prospect revealed intriguing layering within the soft sediments. Long cores of the sediments were collected and physical and chemical properties of the muds were measured in the laboratory to find the cause of the GPR reflections and investigate chemical variability of the muds in time and space.
