Field Sampling Tools
Figure 2. Field cleaning supplies and equipment.
Figure 3 depicts tools used for non-cohesive soils, such as sand or gravel.
The device to the rear of the image is called a cookie cutter. It forms a 4.5-cm-
diameter by 2-cm-high puck when placed on the ground and twisted. The puck
can then be scooped into the compositing bag with one of the stainless steel
sample scoops (AMS Part numbers 428.0206). Not shown is a hammer corer
available from AMS (Part number 404.61) that is used to obtain short (<12-cm)
cores in very rocky soils. This is an all-stainless device with which we have had
very good results.
