Abstract
THE preliminary results of an attempt to estimate sediment influx in a small upland lake using magnetic susceptibility measurements on whole unextruded sediment cores obtained from a grid covering almost the whole area of open water are reported here. The susceptibility variations, reinforced by a wider range of magnetic measurements on individual samples, provide a basis for core correlation over the whole lake. The speed with which such studies can be accomplished makes possible a much more secure empirical basis for calculations of total sediment input versus time than do conventional methods of core correlation and analysis.
