Collecting particles from the ocean

A majority of samples analyzed onboard examine metals and nutrients dissolved in seawater, which requires the water to be filtered before analysis.However, metals and nutrients attached to particles can also tell an interesting story. A group of students from Woods Hole Oceanographic Institute is devoted to collecting particulate samples from the ocean surface to the ocean floor. The samples are collected using specialized pumps that pass large volumes of water through filters to pull out larger particulates (see photo series below). In this picture, the filters are housed in the plastic containers with red and orange tape on top. Under clean conditions, the filters are removed and processed, then re-loaded for the next round of sampling.
