Special Issue Information

Dear Colleagues,

Oceanic currents are a fundamental component of the Earth system through their ability to redistribute heat from the Equator to the poles, and more generally, to transport physical, chemical, biological, and anthropogenic matter and properties across the World Ocean. The strongest currents, which are usually found near the ocean surface, are driven by a combination of wind and pressure gradients in the open ocean, sometimes complemented by other drivers such as tides or breaking surface waves, most notably in the coastal zone that is characterized by particularly complex hydrodynamical processes and land-air-sea interactions. Even in the open ocean, near-surface currents are associated with oceanographic processes acting on a wide range of spatial and temporal scales, from submesoscale and mesoscale turbulence to large-scale wind-driven gyres and thermohaline circulation and over periods of days to decades.

Floating material of various origins including pollutants and biota (e.g., plastic debris, harmful algal blooms, Sargassum algae and other rafts, oil spills) are directly carried by surface ocean currents, sometimes over large distances and long periods, but also through the direct action of wind stress, i.e., windage. Understanding how such material is carried and dispersed by currents, winds, and other geophysical phenomena is paramount for a broad range of applications including, but not limited to search and rescue operations, operational monitoring and forecasting of floating material drift.

For this Special Issue, we invite contributions from the research community working on topics related to surface ocean drift to submit original research papers, as well as review articles and short communications. We welcome numerical and observational approaches, both in situ and remote sensing. More fundamental studies of Lagrangian particle drift or Eulerian passive tracer transport and mixing are also of interest.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The accumulation of plastic debris on land and coastlines and in waterways and garbage patches is one of the greatest ecological concerns of the 21st century. In that context, the sources and pathways of plastic marine debris (PMD) have been increasingly studied in the past ten years. The purpose of this communication was to analyze, thanks to the tracks of two drifting buoys released in May–June 2019 in the North-East Pacific, two features encountered within the Great Pacific Garbage Patch (GPGP): a surface convergence, which could lead to the formation of plastic hotspots, and the persistency of the floating material in this area of the ocean. The evolution of the distance between the buoys was compared with the local circulation field divergence, a Lagrangian plastic dispersal model and sea-level anomalies (SLAs). These analyses highlighted the link between the converging behavior of the drifters and a persistent negative velocity divergence as well as a higher than average-encountered modelled plastic surface density (MPSD). The persistence of the material within the GPGP was observed thanks to the trajectory of the longest persisting drifter in comparison with the trajectory of the GPGP center and extent. Full article

Plastic debris has become an acute marine pollution concern worldwide in modern times. Indonesia is particularly impacted because of its high population density, heavy rainfall rate and numerous coastlines. A Lagrangian analysis was performed to simulate the fate of fictive marine debris drifting along surface currents, including tides and Stokes drift. The fictive particles were released according to the discharge rate of 21 Indonesian rivers and advected over 4 years. Most of the particles were stranded along Indonesian coasts (60%), before 6 months had elapsed (84%) and within a range of 1000 km (76%). The time variability exhibited two seasonal peaks, one centered on January-February and one on June-July, consistent with in situ observations. However, the results underline the complexity of performing direct comparisons between in situ observations and numerical simulations for stranded waste due to limited measurements and the heterogeneity of field methods and protocols.
