Description
|
The sediment material was collected in New Caledonia, immediately frozen and then freeze dried. The sediment was first sieved at 500 µm, ground, and then sieved at 125 µm followed by mechanical homogenization of the collected fraction. The sieving cut-off value (125 µm) was selected to ensure that the physical properties of the material are sufficiently uniform, whilst retaining sufficient material to make an adequate number of units. Aliquots of about 15 g were packed into amber glass bottles with polyethylene caps and sealed in plastic bags. The sample material was labeled IAEA-456.
