Dataset Contact Methods Sampling Description Field sampling involves collecting sediment using a coring tube. Method Step Description Field methods involve collecting sediment using a coring tube. Instrumentation Coring tube Method Step Description Lab methods include collecting all sediment material by extruding the core upwards in stratigraphic intervals. An aliquot is taken from each interval and placed in pre-weighed and dried crucible. Crucibles with aliquots are set to dry for 24 hours in a furnace at 105 degrees Celsius, allowed to cool, and then weighed for dry weight measurements. The process continues for two subsequent rounds in the furnace at 550 degrees Celsius for 3 hours and 1000 degrees Celsius for 1 hour to obtain organic matter and inorganic carbon mass respectively. The interval not used for the aliquot is then frozen, freeze-dried, and homogenized. This material is placed in pre-weighed gamma tubes and weighed. Gamma tube intervals are counted using a germanium detector to detect Radium 226 and Lead 210 levels. Instrumentation Furnace free-dryer mortar and pestle germanium detector Method Step Description Statistical methods include standard deviation and the means.
