Ekman Grab | Water Samplers | Water Sampling Equipment

This is the grab to choose for soft, finely divided littoral bottoms that are free from vegetation, such as sticks and decayed leaves (or with short, erect vegetation only) as well as intermixtures of sand, stones, and other coarse debris. Its specialized function is the taking of quantitative and qualitative samples of macroscopic bottom fauna to determine the productivity of soft bottoms, particularly those composed of finely divided muck, mud, ooze, submerged marl and fine peaty materials. Versatile and durable, it is suited for preliminary as well as more precise observation. It is not recommended for rocky or sandy bottoms or moderate macrophyte growth because small pebbles or macrophyte stems prevent proper jaw close.

Two thin, hinged overlapping lids on top open during descent to let water pass through. They close during retrieval and are held shut by water pressure to reduce washout. The closing springs easily unhook from their loaded position for safe handling during transportation and storage.

An important and distinguishing feature of the Wildco design is the messenger-operated Twin-pin scoop release mechanism. This release is very reliable, has few working parts and is the best of its type in the field.

To operate, attach to a line and pass through the trip mechanism. Set the springs over the knobs and pull the jaws completely apart. Lower the dredge till it rests on the bottom and send a messenger down the line, allowing the springs to close the scoops.
