Anomalous Thermal Behavior of an Amorphous Organic Sediment

  • Richard McGaw


Using transient heating in the cylindrical probe configuration, the thermal conductivity of four organic lake sediments was measured. Each specimen contained over 90% water as a fraction of total weight. Organic matter in three of the specimens was fibrous and not greatly decomposed; at a temperature of 5C, thermal conductivity of these ranged from 2–5% higher than that of pure water. A fourth specimen was gelatinous and gave conductivity values from 1% to 20% less than that of water, with an apparent dependence on heat input. The insitu environment of this specimen was known to be different from that of the others.
