On-line technique for preparingand measuring stable carbon isotopeof total dissolved inorganic carbonin water samples ( d13CTDIC)
carbon isotope composition Total Inorganic Carbon
2015/9/10
A fast and completely automated procedure is proposed for the preparation and determination of d13C of total
inorganic carbon dissolved in water ( d13CTDIC). This method is based on the acidification...
Groundwater-derived dissolved inorganic and organic carbon exports from a mangrove tidal creek: The missing mangrove carbon sink?
Groundwater-derived dissolved inorganic organic carbon exports mangrove tidal creek
2014/4/2
A majority of the global net primary production of mangroves is unaccounted for by current carbon budgets. It has been hypothesized that this “missing carbon” is exported as dissolved inorganic carbon...
Removal of dissolved inorganic carbon in the Yellow River Estuary
