Gravity marine sediment sampling
WebOSIL’s Gravity Corer is a simple and reliable instrument for collecting sediment cores from coastal and deepwater sites for sample analysis. The corer uses the pull of gravity to penetrate the seabed with it’s carbon steel core barrel, which can collect samples of up to three metres in length. WebSediment traps are containers that scientists place in the water to collect particles falling toward the sea floor. The traps collect tiny sediment or larger accumulations called marine snow - made up of organic matter, dead sea creatures, tiny shells, dust and minerals. Analyzing the samples helps scientists understand how fast nutrients and ...
