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...
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...
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...
Bioaccumulation of silver-110m, cobalt-60, cesium-137, and manganese-54 by the freshwater algae Scenedesmus obliquus and Cyclotella meneghiana and by suspended matter collected during a summer bloom event
silver-110m cobalt-60 cesium-137 manganese-54 freshwater algae Scenedesmus obliquus Cyclotella meneghina suspended matter collected summer bloom event
2014/5/22
Laboratory experiments were done to assess 110mAg, 60Co, 137Cs, and 54Mn uptake by two phytoplankton species, the chlorophyte Scenedesmus obliquus and the small diatom Cyclotella meneghiana. Mn and Co...
Daily cycles of suspended sand at coral reefs: A biological control
suspended sand coral reefs A biological control
2014/5/27
Sediment resuspension has a major ecological role in many coastal habitats, lakes, and marine environments. Waves and currents are generally thought to be the major control on sediment resuspension. I...
Influence of stream size on ammonium and suspended particulate nitrogen processing
Influence of stream sizeon ammonium suspended particulate nitrogen processing
2014/5/30
We used 15NH4 tracer additions to determine travel distances of ammonium (NH4 ) and suspended particulate organic nitrogen (SPON) in six streams ranging from second to fifth order located within a sin...
