ClearDataset for "Modeling of vertical microplastic transport by rising bubbles"
This is the dataset for a modeling study on how rising air bubbles in water transport microplastic particles vertically through the water column. The model helps explain why microplastics can be found distributed throughout ocean depths rather than concentrated only at the surface.
Modeling of vertical microplastic transport by rising bubbles
This study modeled the vertical transport of microplastic particles by rising bubbles in the ocean, finding that bubble-mediated transport significantly enhances surface concentration of microplastics and helps explain why surface measurements often show higher particle densities than bulk water predictions suggest.
The rise and rupture of bubbles: applications to biofouling, microplastic pollution, and sea spray aerosols
Researchers studied how rising air bubbles in water collect microplastics and bacteria on their surfaces and transport them to the liquid surface, and how bubble bursting then launches these particles into the air as sea spray — with implications for both aquatic contamination and airborne microplastic exposure.
Numerical simulations of bursting bubbles: effects of contamination on droplet ejection and micro- and nanoplastics transport
Scientists used computer simulations to study how tiny plastic particles get launched into the air when bubbles pop at water surfaces, like in oceans or wastewater treatment plants. They found that contaminants in the water change how bubbles burst and affect how many droplets containing microplastics are released into the air we breathe. This research helps us better understand how microplastics from polluted water can end up in the atmosphere and potentially impact human health through inhalation.
Microparticle dynamics in upper-ocean turbulence: Dataset for analysis, modeling & prediction
Researchers developed and released a comprehensive open-access dataset from nine direct numerical simulations of particle-laden turbulence designed to represent microplastic and biogenic debris dynamics in the upper-ocean layer, incorporating physicochemical effects of biofilm stickiness. The dataset is intended to facilitate modeling and prediction of microplastic distribution and aggregation patterns in marine turbulence, supporting development of mitigation strategies for ocean plastic pollution.
Microplastics segregation by rise velocity at the ocean surface
This study modeled the competing forces of particle buoyancy and turbulent mixing that control the vertical distribution of microplastics in the ocean surface layer, finding that particle rise velocity is the key variable that segregates plastic types and determines how they distribute relative to surface and subsurface measurements.
Nanoscale insight into the interaction mechanism underlying the transport of microplastics by bubbles in aqueous environment
Nanoscale experiments revealed that bubble capture of microplastics in water is governed by hydrophobic interactions and surface charge complementarity between bubbles and MP particles. Understanding these mechanisms is critical for modeling the role of bubbles in transporting MPs from water to air-water interfaces and across environmental compartments.
Elucidating the vertical transport of microplastics in the water column: A review of sampling methodologies and distributions
This review synthesized sampling methodologies and findings on microplastic vertical distribution in the water column, identifying that surface trawl studies dramatically underestimate total water column burdens and that sinking behavior, biofouling, and hydrodynamic processes create complex depth-dependent distribution patterns.
Ups and Downs in the Ocean: Effects of Biofouling on Vertical Transport of Microplastics
Researchers developed the first theoretical model to simulate how biofouling, the growth of microbial biofilms on plastic surfaces, affects the vertical movement of microplastics in the ocean. The model predicts that depending on particle size and density, fouled microplastics may float, sink to the seafloor, or oscillate at intermediate depths. These findings help explain why small microplastics seem to disappear from the ocean surface and suggest they may concentrate at mid-water depths where vulnerable species live.
Numerical analysis of boundary conditions in a Lagrangian particle model for vertical mixing, transport and surfacing of buoyant particles in the water column
This technical modeling paper examines how to accurately simulate the behavior of buoyant particles (like microplastics) rising to the ocean surface in computer models. Improving these simulations helps predict where floating microplastics will accumulate in the ocean.
A comparison of Eulerian and Lagrangian methods for vertical particle transport in the water column
This study compared Eulerian and Lagrangian mathematical methods for modeling how particles including microplastics, plankton, and gas bubbles move vertically in the ocean. Accurate particle transport models are essential for predicting where microplastics accumulate in the water column and ultimately in marine sediments.
Particle Tracking Model
This is a numerical model dataset examining how microplastics absorbed into phytoplankton aggregates settle and cycle through ocean waters — not a standalone research article.
Vertical transport of buoyant microplastic particles in the ocean: The role of turbulence and biofouling
Researchers modeled how turbulence and biofouling interact to determine the vertical movement of buoyant microplastic particles in the ocean. They identified three distinct flow regimes that govern whether microplastics stay at the surface, oscillate, or sink to the seafloor. The study helps explain the observation that even low-density microplastics are found in deep ocean sediments, suggesting biofouling-driven density changes are a key transport mechanism.
The effect of wind mixing on the vertical distribution of buoyant plastic debris
Researchers modeled and measured how wind mixing affects the vertical distribution of buoyant plastic debris in the ocean, finding that turbulent mixing drives plastics below the surface and explains why surface sampling underestimates total plastic concentrations.
Modeling the trajectories of floating and non-floating microplastic particles in the water column
Researchers modeled the trajectories of both floating and non-floating microplastic particles in freshwater and marine water columns, accounting for turbulence-induced mixing, buoyancy differences, and flow characteristics that determine vertical and horizontal distribution. The study highlights that while low-density polymers like polyethylene and polypropylene are expected to concentrate at the surface, turbulent mixing drives significant depth distribution across aquatic environments.

Investigation of dynamic change in microplastics vertical distribution patterns: The seasonal effect on vertical distribution
This study combined targeted field sampling in the Bay of Marseille with numerical simulations to analyze how microplastic vertical distribution patterns in the ocean water column change seasonally, finding that wind mixing and particle buoyancy are key drivers of vertical transport.

This is a reviewer response in the peer review process for a study on modeling vertical particle transport in the ocean, including microplastics and other suspended particles. The review process helps ensure the scientific rigor of models used to track plastic movement in marine environments.
Response to both reviewers
This author response discusses models for predicting the vertical movement of particles in the ocean, including microplastics, nanoparticles, gas bubbles, and biological material. Accurately modeling how microplastics sink or rise in ocean water is essential for understanding their distribution and fate in marine environments.

Comment on egusphere-2023-1624
This modeling study examined how microplastics aggregate and move below the ocean surface, finding that buoyant plastic particles can be concentrated in vorticity-dominated regions. Understanding subsurface microplastic transport is important for predicting where plastic accumulates and how it enters marine food webs.
