Abstract The China Seas include the South China Sea, East China Sea, Yellow Sea, and
Bohai Sea. Located off the Northwestern Pacific margin, covering 4700000 km 2 from …

This paper aims to provide an overview of regional carbon fluxes and budgets in the
marginal seas adjacent to China. The “China Seas” includes primarily the South China Sea …

In this study, we utilize 234Th/238U disequilibrium to determine particulate organic carbon
(POC) export from the euphotic zone in the South China Sea. Depth profiles of 234Th, total …

We have investigated the effect of eddies (cold and warm eddies, CEs and WEs) on the
nutrient supply to the euphotic zone and the organic carbon export from the euphotic zone to …

The spatiotemporal evolution of both U and Th isotopes in a mine effluent highly polluted by
acid mine drainage (AMD) was evaluated. The acidic tributary, which born from the outflows …

Next to the city of Huelva (SW of Spain), around 100 Mt of phosphogypsum (PG) are stored
in stacks on the salt-marshes of the Tinto River estuary covering a surface of about 1000 ha …

In order to examine the sources of plutonium (Pu) and elaborate its scavenging and
accumulation processes, 240 Pu/239 Pu atom ratios and 239+ 240 Pu activities in the water …

To understand carbon cycling in marginal seas better, particulate organic carbon (POC)
concentrations, POC fluxes and primary production (PP) were measured in the East China …

210Po, 210Pb and Be isotopes (eg 7Be and 10Be) have long been used as proxies of
particle/sediment dynamics, carbon cycling, and oceanographic investigations of coupled …

Abstract The Odiel and Tinto rivers show singular characteristics due to the significant acid
mine drainage (AMD) generated in the first section of their basins and the phosphogypsum …
