Reinterpretation of oceanic 230Th profiles based on decadal export productivity (2003–2010)

Abstract Understanding 230Th distributions in the global ocean is important to support and guide the use of this important radioactive nuclide in multiple aspects of oceanographic research, and this issue is now revisited. Based on estimates of export productivity (EP) over 2003–2010 and assuming 23...
