Effects of phytoplankton community on production, size and export of large aggregates: A world-ocean analysis
phytoplankton community production, size export of large aggregates: A world-ocean
2014/4/17
We recorded vertical profiles of size distributions of large particles (.100mm) to a 1000-m depth in the Atlantic, Indian, and Pacific Oceans and in the Mediterranean Sea with theUnderwater Video Prof...
Vertical distribution of aggregates (>110 μm) and mesoscale activity in the northeastern Atlantic: Effects on the deep vertical export of surface carbon
Vertical distribution of aggregates (>110 μm) mesoscale activity in the northeastern Atlantic Effects on the deep vertical export of surface carbon
2014/4/22
Spatial and temporal variability in the distribution of marine aggregates (>110 mm) was studied using underwater video profilers in an area off the Iberian Peninsula and Azores Islands dominated by me...
Direct measurement of diffusivity within diatom aggregates containing transparent exopolymer particles
Direct measurement of diffusivity diatom aggregates transparent exopolymer particles
2014/4/22
We present the first direct measurements of apparent diffusivity within diatom aggregates using a diffusivity microsensor. Transparent exopolymer particles (TEP) and aggregate dry mass (TEP and cells)...
Lethal marine snow: Pathogen of bivalve mollusc concealed in marine aggregates
Lethal marine snow marine aggregates
2014/5/13
We evaluated marine aggregates as environmental reservoirs for a thraustochytrid pathogen, Quahog Parasite
Unknown (QPX), of the northern quahog or hard clam, Mercenaria mercenaria. Positive results ...
Diffusion and advection within and around sinking, porous diatom aggregates
Diffusion advection within around sinking porous diatom aggregates
2014/5/27
Fluid motion within and around sinking aggregates is an important factor in particle scavenging and solute exchange between sinking aggregates and the surrounding water and, hence, vertical fluxes and...
Small-scale oxygen fluxes and remineralization in sinking aggregates
Small-scale oxygen fluxes remineralization sinking aggregates
2014/6/10
Sinking aggregates are the major component of the vertical particulate flux in most regions of the ocean. Controlling factors for aggregate remineralization rates and solute exchange with the surround...
Microbial degradation of organic carbon and nitrogen on diatom aggregates
organic carbon nitrogen
2014/5/30
The major pathways of transformation of particulate organic matter by heterotrophic bacteria are respiration and
production of new biomass. Until today only a limited number of studies have measured ...
Mass sedimentation of picoplankton embedded in organic aggregates
Mass sedimentation picoplankton organic aggregates
2014/6/17
During a survey cruise crossing the Subtropical Front over the Chatham Rise east of New Zealand, we made the first observation in High Nutrient Low Chlorophyll waters of massive sedimentation of picop...
