Ekman grab

An Ekman grab is a specialized tool used by scientists to collect sediment samples from the ocean floor. It consists of two hinged arms with open jaws that are lowered to the seabed. Once dropped, the jaws close when the device is pulled upward, capturing a small amount of sediment. This sample helps researchers analyze the composition, layers, and properties of seabed materials, providing important information for fields like geology, ecology, and environmental monitoring. It’s a reliable and efficient way to obtain sediment samples from challenging underwater environments.
