The Ekman grab set is used for sampling of soft sediment, free from debris and plant growth. There is a rod (4.9 feet / 1.5 meter) available for the rod-operated use of the Ekman grab in shallow water.
This grab is intended for use in soft sediment and has a capacity of 3.5 liter. Its dimensions are 5.9 x 5.9 x 5.9 inch (152 x 152 x 152 millimeter) and the entire instrument is made of inert stainless steel. Thanks to the overlapping flaps, nothing will be lost of the sample.
For the use of the Ekman grab with rod in shallow water, a rod of 1.5 meter length is also available. The Ekman Grab set is equipped with a drop-weight system, so that sampling can be carried out at any depth.
Two thin hinging flaps are open while the grab is lowered. The spring-loaded flaps close when a drop-weight is dropped (cable operated) or a button is pressed (rod operated). Samples can, therefore, also be taken from very soft top layers. The pressure of the sample prevents much loss of material. Nevertheless, please note that small stones or stalks may prevent the grab from closing properly.
