Carbon sequestration and zooplankton lunar cycles: Could we be missing a major component of the biological pump?
Carbon sequestration zooplankton lunar cycle
2014/4/17
The plankton outburst during the so-called late winter bloom in subtropical waters was studied in relation to

Role of sulfate reduction methane production organic carbon degradation eutrophic fjord sediments
2014/4/17
The anaerobic mineralization of buried organic matter through sulfate reduction and methanogenesis was studied in 2-m-long piston cores of organic-rich, silty-clay sediment from two sites in Limfjorde...
Effects of fetch and dissolved organic carbon on epilimnion depth and light climate in small forest lakes in southern Sweden
ight climate epilimnion depth
2014/4/16
We sampled small (0.03 to 3.3 km2
surface area) forest lakes in southern Sweden during two summers to
investigate how concentration of dissolved organic carbon (DOC) and lake size influence epilimni...
Simultaneous measurements of nitrate, oxygen, and carbon dioxide on oceanographic moorings: Observing the Redfield ratio in real time
nitrate oxygen carbon dioxide
2014/4/16
Autonomous observations of dissolved nitrate, oxygen, and total inorganic carbon (TCO2

Inorganic carbon and biological oceanography above a shallow oxygen minimum in the entrance to the Gulf of California in the Mexican Pacific
oxygen minimum Inorganic carbon
2014/4/16
The eastern Pacific intermediate oxygen minimum layer (OML) is particularly well-developed and shoals close
to the Mexican coast. We obtained hydrographic profiles including oxygen concentration [O],...

river-borne soil organic Gulf of Lions
2014/4/16
We determined the spatial distribution patterns of the Branched and Isoprenoid Tetraether (BIT) index, a
specific proxy of riverborne soil organic carbon (OC) input from land to the ocean, by analyzi...
Potential carbon fixation via methane oxidation in well-oxygenated riverbed gravels
via methane oxidation well-oxygenated riverbed gravels
2014/4/16
Due to a combination of local methanogenesis and high background concentrations in the groundwater, water
in the River Lambourn is 51 times supersaturated with methane (162 nmol CH4 L21
). Pore-wate...
The role of effective discharge in the ocean delivery of particulate organic carbon by small, mountainous river systems
The role of effective discharge in the ocean delivery particulate organic carbon by small mountainous river systems
2014/4/16
Recent research has shown that small, mountainous river systems (SMRS) account for a significant fraction of the global flux of sediment and particulate organic carbon (POC) to the ocean. The enormous...

Isotope enrichment mangrove ests separates microphy tobenthos anddetritus carbon sources animals
2014/4/16
Microphytobenthos (MPB) and mangrove detritus were labeled with a carbonisotope (13C) in separate experiments to quantify their contributions to the nutrition of major faunal components within a mangr...

Long-term patterns dissolved organic carbon lakes across eastern Canada a pronounced climate effect
2014/4/16
We analyzed the 21-yr dynamics of dissolved organic carbon (DOC) in 55 lakes during ice-free periods in five regions across eastern Canada in relation to total solar radiation (TSR),precipitation, air...
