DescriptionModel of the flux of sinking oceanic particles.webp
English: Model of the flux of sinking oceanic particles
Sinking oceanic particles (inset images) encompass a wide range of shape, porosity, ballast and other characteristics. This model attempts to capture some of the predominant features that influence the shape of the sinking flux profile (red line). In the simplified model, shown in the inset, the spheres represent either solid particles or aggregates. These particles (initial radius a0) produced within the sunlit euphotic zone (green region extending to zeu) sink at a rate predicted by Stokes law. They slow as they reach greater depths due to their shrinking volume and increasing water density and would entirely disappear at zdis.
The images of inset particles are sinking phytoplankton, pellets and aggregates captured in particle-preserving gel traps by Dr. Colleen Durkin.
