Abstract
This study aims at the investigation of the spatial distribution and vertical profile of dissolved silver in the waters of the East China Sea, South China Sea and Philippine Sea. Results show that Taiwan Straits surface water and the coast of river silver concentrations are high to compare to the open ocean areas (the west Philippine sea and the north South China Sea). Silver concentrations range from 0.5~65pM. Silver distributions were characterized by decreasing long-shore southward and increasing near-shore concentrations near river mouths indicating anthropogenic inputs.even section vertical profiles of silver concentrations in the South China Sea and Western Philippine Sea show that silver concentrations are low in surface waters (< 7 pM) and relatively high (37 pM) in the deep waters. This nutrient-type distribution is further evidenced by the significant correlation of silver with silicate concentrations. Silver concentrations in the west Philippine sea gradually increase towards to the South China Sea, but they do not compare well to ours in the North Pacific deep water. Comparison to the northwest Pacific studies are discussed based on methodological differences.
