image: The scientists used a CTD (conductivity, temperature, depth) rosette to collect water samples during a research cruise in October 2011 along a 2,500-mile stretch in the Pacific Ocean, from Hawaii to Samoa. The transect cut across regions with widely different concentrations of nutrients, from areas rich in iron to the north to areas near the equator that are rich in phosphorus and nitrogen but devoid of iron. This material relates to a paper that appeared in the 5 Sept. 14, issue of Science, published by AAAS. The paper, by M.A. Saito at Woods Hole Oceanographic Institution in Woods Hole, MA, and colleagues was titled, 'Multiple nutrient stresses at intersecting Pacific Ocean biomes detected by protein biomarkers.' view more
