Research Abstract |
Isotopic ratios of heavy elements are widely noticed as novel measures in marine chemistry. In the present study, we have analyzed seawater samples collected from the Pacific, Southern and Atlantic Oceans, confirming that the isotopic composition of dissolved molybdenum is uniform throughout the global ocean. We developed a precise method for isotopic analysis of dissolved copper in seawater. We also optimized an isotopic analysis method for molybdenum and tungsten in sediments. The isotopic ratios of these elements are promising as a tracer of biogeochemical cycling and a proxy in paleoceanography.
