Midwater zooplankton and suspended particle dynamics in the North Pacific Subtropical Gyre: A stable isotope perspective
North Pacific Subtropical Gyre Midwater zooplankton
2014/4/2
We used amino acid (AA) compound-specific isotope analysis (d15NAA and d13
CAA values) of midwater
zooplankton and suspended particles to examine their dynamics in the mesopelagic zone. Suspended pa...
Exchange between suspended and sinking particles in the northwest Mediterranean as inferred from the organic composition of in situ pump and sediment trap samples
suspended sinking particles northwest Mediterranean as inferred from the organic
2014/4/16
The extent to which sinking particles disaggregate and exchange with surrounding material affects the
efficiency of particulate organic carbon export to the deep sea. In 2003 and 2005, we compared th...
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...
Dispersion of Small Suspended Particles in a Wave Boundary Layer
Small Suspended Particles Wave Boundary Layer
2008/12/17
The dispersion of heavy suspensions in a wave boundary layer over a nonerodible bed is examined theoretically. Focusing attention on the horizontal variation of the ambient wave pattern, an effective ...
Characterization of suspended particles in Everglades wetlands
suspended particles Everglades wetlands
2014/4/22
We report the concentration, phosphorus (P) and nitrogen (N) content, and size and chemical fractionation of fine suspended particles (0.2-100 μm) and colloids (3 kilodalton [kDa]-0.1 μm) in the surfa...
Variations in the optical properties of terrigenous mineral-rich particulate matter suspended in seawater
Variations in the optical properties terrigenous mineral-rich particulate matter suspended in seawater
2014/4/21
From laboratory measurements, we determined the spectral mass-specific absorption, ap*(λ), and scattering, bp*(λ, coefficients for terrigenous mineral-rich particulate assemblages suspended in seawate...
Suspended minerogenic particles in a reservoir: Light-scattering features from individual particle analysis
Suspended minerogenic particles a reservoir Light-scattering features individual particle analysis
2014/4/22
Light-scattering attributes of minerogenic particles in a reservoir, where these particles dominate over a wide range of light-scattering levels, were characterized by an individual particle analysis ...
Pectenotoxin-2 and dinophysistoxin-1 in suspended and sedimenting organic matter in the Baltic Sea
Pectenotoxin-2 dinophysistoxin-1 suspended and sedimenting organic matter Baltic Sea
2014/5/5
Dinophysis acuminata, D. norvegica, and D. rotundata occur regularly in the Baltic Sea summer plankton. They are known to produce diarrhetic shellfish poisoning (DSP) toxins in coastal areas worldwide...
Red and black tides: Quantitative analysis of water-leaving radiance and perceived color for phytoplankton, colored dissolved organic matter, and suspended sediments
Red and black tides water-leaving radiance
2014/5/5
Using field measurements and quantitative modeling, we demonstrate that red coloration of the sea surface is
not associated with any particular group of phytoplankton and is strongly dependent on the...
Release of trace oxyanions from littoral sediments and suspended particles induced by pH increase in the epilimnion of lakes
trace oxyanions littoral sediments suspended particles induced pH increase epilimnion of lakes
2014/5/9
We measured the vertical distributions of dissolved vanadium (V), molybdenum (Mo), and tungsten (W) during a stratification period in Lakes Biwa, Ikeda, and Unagi-ike, which are located in the tempera...
Attachment to suspended particles may improve foraging and reduce predation risk for tintinnid ciliates
Attachment to suspended particles improve foraging reduce predation risk tintinnid ciliates
2014/5/19
We describe a new behavior of planktonic ciliates. The field-collected tintinnid Eutintinnus inquilinus attached with its lorica to a range of surfaces, including particulate aggregates. Most tintinni...
Variations in the mass-specific absorption coefficient of mineral particles suspended in water
Variations in the mass-specific absorption coefficient mineral particles suspended water
2014/5/14
We examined the light-absorption properties of various samples of mineral particles suspended in water, which included pure mineral species (quartz, calcite, illite, kaolinite, and montmorillonite) an...

2014/5/14
The spectral optical properties of Asian mineral dust suspended in seawater exhibit significant variability associated with the origin (and, hence, the chemistry and mineralogy) and particle size dist...
