Bioactive trace Metal distributions and Biogeochemical controls in the Southern ocean
Metal distributions Biogeochemical controls
2015/7/15
Extensive sampling in many regions of the Southern Ocean has
demonstrated that surface water concentrations of dissolved Fe are low enough
to limit phytoplankton growth. In contrast, there is curr...
Trace metal cycling in the deep water of the South China Sea: The composition, sources, and fluxes of sinking particles
Trace metal cycling in the deep water the South China Sea composition sources fluxes of sinking particles
2014/4/8
Moored sediment traps were deployed for 1 yr at depths of 120, 600, and 3500 m in the water column to investigate the trace metal (M) (Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) composition, sources, ...
The influence of river plume dynamics on trace metal accumulation in calanoid copepods
iver plume dynamics calanoid copepods
2014/4/17
The concentrations of Ag, Cd, Cu, Hg(II), monomethylmercury (MeHg), Pb, and Zn were measured and
modeled in calanoid copepods collected from the Hudson River plume in April 2005 and May 2006. Copepod...
Trace metal cycling in the surface water of the South China Sea: Vertical fluxes, composition, and sources
Trace metal cycling the surface water the South China Sea: Vertical fluxes composition sources
2014/4/16
We deployed floating traps in the surface waters of the South China Sea on four occasions at depths of 30 m,100 m, and 160 m from 2006 to 2007 to quantify vertical metal fluxes in the surface water an...
The trace-metal composition of size-fractionated plankton in the South China Sea: Biotic versus abiotic sources
size-fractionated plankton South China Sea
2014/4/22
We report the elemental composition (P, Si, Al, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) in the size-fractionated
plankton and suspended particulate matter (SPM) in the surface waters of the South China Se...
Effects of dust deposition and river discharges on trace metal composition of Trichodesmium spp. in the tropical and subtropical North Atlantic Ocean
dust deposition river discharges trace metal composition Trichodesmium spp. tropical subtropical North Atlantic Ocean
2014/5/4
We present the elemental composition (Al, Cd, Co, Cu, Fe, Mn, Mo, Ni, V, Zn, and P) of field-collected Trichodesmium populations. To distinguish the effects of river discharges (Amazon and Niger River...
Phosphorus and trace metal limitation of algae and bacteria in Lake Superior
Phosphorus and trace metal algae and bacteria Lake Superior
2014/5/14
We performed a set of nutrient-enrichment bioassay experiments using metal-clean protocols, testing for macronutrient and micronutrient limitation of algae and bacteria in western Lake Superior. Our a...
Trace metal assimilation and release budget in Daphnia magna
Trace metal assimilation release budget Daphnia magna
2014/5/26
The assimilation efficiency (AE), efflux rate, and release budget of Cd, Cr(III), Se(IV), and Zn by a freshwater zooplankton Daphnia magna were measured under different food concentrations. The AEs of...
