8) Store the <strong>peat</strong> samples <strong>in</strong> accordance with their <strong>in</strong>tended uses. For<br />
example, for <strong>peat</strong> <strong>carbon</strong> dat<strong>in</strong>g, the samples can be stored <strong>in</strong> a PVC<br />
pipe cut <strong>in</strong> half and covered with alum<strong>in</strong>ium foil. For the determ<strong>in</strong>ation<br />
of water content (% volume) and BD, the <strong>peat</strong> and water from the auger<br />
must be quantitatively transferred <strong>in</strong>to plastic bags (Figure 9) so that<br />
no fluid is spilled and the volume does not change (from 500 cm 3 ).<br />
Sometimes the 50 cm-long samples need to be cut <strong>in</strong>to 2–3 parts if, for<br />
example, there are differences <strong>in</strong> maturity or if there is a layer of clay or<br />
ash at certa<strong>in</strong> depths. Each piece of 10 cm length has a volume of 100<br />
cm 3 .<br />
