WebHence, particles and aggregates at a specific depth may be a cluster of small single-celled phytoplankton and individual mineral particles, as well as large marine snow and fecal pellets formed from a mixture of organic and inorganic particles (e.g., lithogenic material). These particles and aggregates may range in size from μm to cm and ... Web17 jan. 2024 · Whereas the oceanic iron cycle is partially controlled by biological processes, it is, unlike major nutrients, widespread in the water column in the particulate form, notably as lithogenic particulate iron. It is a particle-reactive element, sensitive to scavenging processes (i.e., adsorption/desorption onto/from sinking particles).
