Special Issue Information

Dear Colleagues,

Internal waves, particularly internal tides, are thought to be the main mixing mechanism in the deep ocean. Deep-ocean mixing is important to the global conveyor belt and the recirculation of nutrients in the ocean. Our Special Issue will cover both observations and simulations of internal waves and internal tides in various locations. We are very interested in the induction of turbulence and mixing by internal waves, and in how this mixing is parameterized in ocean circulation and climate models. Presently, one of the biggest shortcomings in these models is the handling of mixing. In particular, internal wave studies based on satellite data analysis and artificial-intelligence-based methods are also welcome.

This Special Issue includes, but is not limited to, the following topics:

  • Internal wave;
  • Internal tide;
  • Internal solitary wave;
  • Near-inertial internal wave;
  • Internal-wave-induced mixing;
  • Satellite altimetry;
  • Numerical simulation;
  • Turbulent mixing;
  • Model mixing parameterization;
  • Internal-wave-current interaction.

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. Water is an international peer-reviewed open access semimonthly 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).

As the Arctic Ocean continues to warm, both the extent and thickness of sea ice have dramatically decreased over the past few decades. These changes in ice have an impact on sea ice motion, including sea ice inertial oscillations (SIIO). However, the spatial pattern and temporal variations of Arctic SIIO remain poorly understood. In this study, the spatiotemporal characteristics of Arctic SIIO between 1979 and 2019 are revealed based on the sea ice drifting buoy dataset from the International Arctic Buoy Program (IABP). The results indicate the significant enhancement of SIIO during 1979–2019, with the trend of 7.84 × 10−3 (±3.34 × 10−3) a−1 (a−1 means per year) in summer and 1.92 × 10−3 (±0.80 × 10−3) a−1 in winter. Compared with the first 30 years, the magnitude of SIIO in 2009–2019 increases by 66% in summer and 21% in winter. Spatially, the remarkable enhancement of SIIO during 2009–2019 is found in most of the Arctic Ocean. Especially in summer, SIIO are significantly intensified in marginal seas, including the Beaufort Sea, East Siberian Sea and Laptev Sea, which is mainly correlated with the decrease of sea ice concentration in recent years. This study is anticipated to provide insights for spatiotemporal variation of Arctic sea ice inertial motion in recent decades. Full article
