Phytoplankton productivity and export sequester climatically significant quantities of
atmospheric carbon dioxide as particulate organic carbon through a suite of processes …

Groundwater is essential for regional ecological-economic system and is an important
resource of drinking water, especially in the Chinese Loess Plateau (CLP), where is a typical …

Groundwater-derived solute fluxes to the ocean have long been assumed static and
subordinate to riverine fluxes, if not neglected entirely, in marine isotope budgets. Here we …

Trace metals and metalloids in aquatic ecosystems may lead to adverse effects on the
survival of fish, especially in the sensitive life stages of vulnerable species. It is still unknown …

Serpentinites in subduction zones are important fluid reservoirs for crust-mantle interaction
and arc magma formation. The serpentinite-derived fluids can carry fluid-mobile elements …

Mid-ocean ridge (MOR) hydrothermal vent fluids are enriched with dissolved barium, but
due to barite (BaSO 4) precipitation during mixing between Ba-bearing vent fluids and SO 4 …

Barium (Ba) isotope variations offer the potential to trace environmental processes, including
long-term changes in river discharge and marine export production. Riverine inputs are an …

Stable barium (Ba) isotopes are emerging as tracers for the recycling of crustal material into
the mantle. Small but significant Ba isotope variations have been found in global MORB (δ …

The compositions of ocean island basalts (OIB) can record signatures of ancient subducted
crust that has been recycled through the mantle. Based on their radiogenic isotope, major …

In order to better understand how stable metal isotope signals in large rivers can be used to
constrain present and past weathering, the seasonal riverine Mgsingle bond Sr isotopic …
