Bubbles, though seemingly simple, are fascinating in fluid mechanics and play a crucial role in environmental processes. As they rise through marine columns, bubbles scavenge contaminants through flow mechanics and physical chemistry, including biocontaminants such as microbial extracellular polymeric substances. These biocontaminants form intricate three-dimensional polymeric networks, creating a viscoelastic coating layer on the bubbles’ surfaces. When a contaminated bubble with such a layer reaches the air-liquid interface and bursts, it produces a distinct “beads-on-a-string” pattern during the formation of the Worthington jet, ejecting biocontaminants as small droplets into the atmosphere. By varying the compound layer fraction and polymer concentration, a diverse range of bursting dynamics and jetting patterns can be observed. My research focuses on understanding the bursting dynamics of such contaminated bubbles, as this is crucial due to their role in transporting contaminants within marine ecosystems.
