Planktonic foraminifer micropaleontologist Arun Singh (Banaras Hindu University, India) sieves sediment to wash away the smaller particles (which include clay and nannofossils) from the foraminifers that he is interested in. Foraminifers are roughly the size of sand grains—much larger than the nannofossils being washed down the drain! (Credit: Bill Crawford, IODP JRSO) [Photo ID: exp355_042]
