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)...
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...
Microbial degradation of organic carbon and nitrogen on diatom aggregates
organic carbon nitrogen

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 ...
