Ekman Grab

This is the grab to choose for soft 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. The specialized function of this dredge 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.
