image: Trichodesmium forms colonies of a wide variety of shapes are clearly visible to the naked eye (the diameter of the test tube is about the same as a US$ quarter). These remarkable organisms drive a previously unknown redox cycle of phosphorus in the upper ocean. This material relates to a paper that appeared in the May 15, 2015 issue of Science, published by AAAS. The paper, by B.A.S. Van Mooy at Woods Hole Oceanographic Institution in Woods Hole, MA, and colleagues was titled, 'Major role of planktonic phosphate reduction in the marine phosphorus redox cycle.' view more
