| Definition | A simple clam-shell sediment grab penetrating approximately 20cm with a typical sampling area of 0.1m2 (but grab sizes can vary). On descent two levers with buckets at their ends are spread like open scissors that unlock on hitting the seabed. When pulled upwards the two buckets close and grab a sample. This is subject to more disturbance than by Craib or box corers. |
