| Definition | A stainless steel sediment sampler designed to retrieve soft-sediment samples from rivers, harbours and shallow marine areas. The samples retrieved are semi-disturbed from the surface layers. The grab is lowered using an attached 30 m cable or rod. It has two spring-loaded jaws which are in the open position when lowered. The jaws are closed when a drop-weight is dropped (cable operated) or a button is pressed (rod operated). The jaws overlap once closed to prevent any loss of sample. The Ekman grab can be supplied with a 1.5m rod or cable for use in very shallow water. It has a sample volume of 3.5 litres, weighs 7 kg, and its overall dimensions are 152 x 152 x 152 mm. | ||
