Ocean Waters Prevent Release Of Ancient Methane（图）
Ocean Waters Prevent Release Ancient Methane
2018/2/1
Ocean sediments are a massive storehouse for the potent greenhouse gas methane.Trapped in ocean sediments near continents lie ancient reservoirs of methane called methane hydrates. These ice-like wate...
The effect of groundwater advection on salinity in pore waters of permeable sediments
groundwater advection salinity in pore waters permeable sediments
2014/4/18
Measurements of the upward advection and pore-water profiles of salinitywere made at three coastal settings(the Venice Lagoon, Italy; Jamaica Bay, New York; and Mattituck, New York). Coincident measur...
Significant contribution of passively sinking copepods to the downward export flux in Arctic waters
Significant contribution passively sinking copepods downward export flux Arctic waters
2014/4/17
Typically, all undecomposed metazoans found in formalin-poisoned cups of sediment traps are considered to be active intruders (or ‘‘swimmers’’) and are removed to prevent an overestimation of the down...
Spectral variations of light scattering by marine particles in coastal waters, from visible to near infrared
coastal waters light scattering marine particles
2014/4/18
Field measurements and Mie calculations of the particulate light-scattering coefficient (bp, in m21
) in the nearinfrared and visible spectral domains are combined to quantify and model the effect of...
Abundance and variation of colloidal organic phosphorus in riverine, estuarine, and coastal waters in the northern Gulf of Mexico
colloidal organic phosphorus Abundance
2014/4/18
The abundance of colloidal organic phosphorus (COP) and colloidal inorganic phosphorus (CIP) was
quantitatively determined using an ultrafiltration permeation model for riverine, estuarine, and coast...
Evidence of prokaryotic metabolism on suspended particulate organic matter in the dark waters of the subtropical North Atlantic
prokaryotic metabolism particulate organic matter
2014/4/17
The distribution of prokaryotic abundance (PA), respiratory activity (ETS), heterotrophic production (PHP),
and suspended particulate (POM) and dissolved (DOM) organic matter was determined in the me...
Increases in the longwave photobleaching of chromophoric dissolved organic matter in coastal waters
longwave photobleaching chromophoric dissolved organic matter
2014/4/17
Salinity effects on the photobleaching of chromophoric dissolved organic matter (CDOM) due to coastal
mixing were investigated through a comparative study of surrogate and surface-water CDOM. Suwanne...
Persistence of iron(II) in surface waters of the western subarctic Pacific
Persistence of iron surface waters the western subarctic Pacific
2014/4/21
The distribution of dissolved iron(II) [Fe(II)] was studied in surface waters of the western subarctic Pacific during the Subarctic Pacific Iron Experiment for Ecosystem Dynamics Study-II (SEEDS II) i...
A comparative study of responses in planktonic food web structure and function in contrasting European coastal waters exposed to experimental nutrient addition
planktonic food web contrasting European coastal waters
2014/4/30
We quantify, compare, and generalize responses of experimental nutrient loadings (LN
) on planktonic community
structure and function in coastal waters. Data were derived from three mesocosm experim...
Characterization of particulate proteins in Pacific surface waters
particulate proteins Pacific surface waters
2014/5/19
We investigated molecular characteristics of particulate proteins in Pacific surface waters using two-dimensional electrophoresis (2DE). Most proteinaceous materials estimated by dye-binding methods w...
Spatio-temporal geochemistry of mercury in waters of the Tapajo′s and Amazon rivers, Brazil
he Tapajo′s Amazon rivers
2014/6/9
Spatial and temporal variations of mercury (Hg) concentrations were monitored in the surface waters from the
lower portion of the Tapajo′s River, the Arapiuns River, its principal tributary, and the ...
