Distribution of 3H and 14C in the Pacific Ocean and its connection with climate change
Abstract:
Tritium 3H (T1/2 = 12.3 y) and radiocarbon 14C (T1/2 = 5730 y) have been long recognized as powerful tools to trace movement of seawater masses, and various physical, geochemical and biological processes in the oceans. During the last three decades, their content in the Pacific Ocean surface and deep waters have been screened several times. Based on these datasets, we investigated spatial and temporal changes in 3H and 14C concentrations in the Pacific Ocean over the last thirty years. The main goal of the study was to evaluate whether the distribution patterns of the radionuclides of interest were potentially modified within the prevailing climate change, which has been affecting, e.g., stratification of global ocean.
