GEOTRACES—A Global Study of the Marine Biogeochemical Cycles of Trace Elements and Their Isotopes
Marine Biogeochemical Cycles Trace Elements Their Isotopes
2015/7/28
Since the late 1990s there has been a growing impetus for a comprehensive global study of the marine biogeochemical cycles of trace elements and their isotopes (TEIs). This has led to the development ...
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...
Nanofibrils and other colloidal biopolymers binding trace elements in coastal seawater: Significance for variations in element size distributions
Nanofibrils other colloidal biopolymers binding trace elements in coastal seawater:Significance variations in element
2014/4/16
Colloidal size spectra of Fe, Cu, Ag, La, and Pb were determined by asymmetrical flow field–flow fractionation coupled to high-resolution inductively coupled plasma mass spectrometry, in samples from ...
Contrasting biogeochemistry of six trace metals during the rise and decay of a spring phytoplankton bloom in San Francisco Bay
biogeochemistry six trace metals during the rise decay of a spring phytoplankton bloom San Francisco Bay
2014/4/22
The spring 2003 phytoplankton bloom in South San Francisco Bay (South Bay) affected the cycling of Mn, Co, Zn, Ni, and Pb, but not Cu. We followed this diatom bloom for 2 months, capturing a peak in c...
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...
Long-term changes in legacy trace organic contaminants and mercury in Lake Ontario salmon in relation to source controls, trophodynamics, and climatic variability

2014/5/5
We used long-term (20+ yr) datasets to determine how the sum of 209 polychlorinated biphenyl congeners
([SPCB]), dodecachloropentacyclodecane ([mirex]), para-para dichlorodiphenyltrichloroethane ([ p...

Photo-oxidation dissolved organic matter in river water trace element speciation
2014/5/4
To investigate the effect of photodegradation of fluvial dissolved organic matter (DOM) on dissolved trace element distributions, we performed a 3-week incubation of water from the lower Pearl River (...
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...
Natal trace-elemental signatures in the otoliths of an open-coast fish
