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...
Observing Biogeochemical Cycles at Global Scales with Profiling Floats and Gliders: Prospects for a Global Array
Biogeochemical Cycles Global Scales

Chemical and biological sensor technologies have advanced rapidly in the past five years. Sensors that require low power and operate for multiple years are now available for oxygen, nitrate, and a var...
Benthic biogeochemical cycling, nutrient stoichiometry, and carbon and nitrogen mass balances in a eutrophic freshwater bay
Benthic biogeochemical cycling nutrient stoichiometry
2014/4/18
Green Bay, while representing only ,7% of the surface area and ,1.4% of the volume of Lake Michigan,
contains one-third of the watershed of the lake, and receives approximately one-third of the total...
Zinc isotope composition of settling particles as a proxy for biogeochemical processes in lakes: Insights from the eutrophic Lake Greifen, Switzerland
Zinc isotope composition a proxy for biogeochemical processes
2014/4/17
The isotope composition of zinc (Zn) was determined in settling particles collected monthly over a year in the
hypolimnion of the eutrophic Lake Greifen (Switzerland) in order to explore the potentia...
Coupling of near-bottom seston and surface sediment composition: Changes with nutrient enrichment and implications for estuarine food supply and biogeochemical processing
near-bottom seston surface sediment composition Changes with nutrient enrichment estuarine food supply biogeochemical processing
2014/5/8
We compared near-bottom seston and surface sediment composition in Cape Cod estuaries receiving different N loads to determine whether eutrophic-driven changes in seston and sediment composition occur...
