In this article, the authors investigated the 3D development of a marine oil spill on the ocean surface and in the water column using numerical model simulations, including wave entrainment of oil, two alternative formulations for the droplet size and turbulent mixing.Abstract:
. Vertical and horizontal transport mechanisms for marine oil spills
are investigated using numerical model simulations. To realistically resolve
the 3-D development of a spill on the ocean surface and in the water column,
recently published parameterizations for the vertical mixing of oil spills
are implemented in the open-source trajectory framework OpenDrift
( https://doi.org/10.5281/zenodo.1300358 , last access: 7 April 2018). The parameterizations include the
wave entrainment of oil, two alternative formulations for the droplet size
spectra, and turbulent mixing. The performance of the integrated oil spill
model is evaluated by comparing model simulations with airborne observations
of an oil slick. The results show that an accurate description of a chain of
physical processes, in particular vertical mixing and oil weathering, is
needed to represent the horizontal spreading of the oil spill. Using
ensembles of simulations of hypothetic oil spills, the general drift behavior
of an oil spill during the first 10 days after initial spillage is evaluated
in relation to how vertical processes control the horizontal transport.
Transport of oil between the surface slick and the water column is identified
as a crucial component affecting the horizontal transport of oil spills. The
vertical processes are shown to control differences in the drift of various
types of oil and in various weather conditions.read more

TL;DR: In this paper, the authors comprehensively discuss what is known about the different processes that govern the transport of floating marine plastic debris in both the open ocean and the coastal zones, based on the published literature and referring to insights from neighbouring fields such as oil spill dispersion, marine safety recovery, plankton connectivity, and others.

The regional oceanic modeling system (ROMS): a split-explicit, free-surface, topography-following-coordinate oceanic model
TL;DR: In this paper, a split-explicit hydrodynamic kernel for a realistic oceanic model is proposed, which addresses multiple numerical issues associated with mode splitting, and is compatible with a variety of centered and upstream-biased high-order advection algorithms, and helps to mitigate computational cost of expensive physical parameterization of mixing processes and submodels.

The Role of Surface-Wave Breaking in Air-Sea Interaction
TL;DR: In this paper, the authors proposed a model to predict the occurrence and dynamics of breaking, which is a major impediment to the development of better wind-wave and mixed-layer models, and showed that modern acoustic and electromagnetic oceanographic instrumentation should lead to significantly improved measurements of breaking in the near future.

TL;DR: Based on profile observations and a one-dimensional column model, Wang et al. as mentioned in this paper demonstrate that plastic debris is vertically distributed within the upper water column due to wind-driven mixing, which suggests that total oceanic plastics concentrations are significantly underestimated by traditional surface measurements, requiring a reinterpretation of existing plastic marine debris data sets.
