Assessing the uses of 230Th, 232Th and 231Pa as proxies in the past and modern ocean

Assessing the uses of 230Th, 232Th and 231Pa as proxies in the past and modern ocean

<p>Thorium-230 and protactinium-231 have been widely used as proxies of oceanic processes in both modern and past marine environment. Their application as such proxies is, however, limited by sparse data from the modern ocean with which to characterize their distribution and behavior. This the...
