During the past several years, research into the frontal divisions of the ocean has been particularly intensive. The significance of this lies not only in the fact that, in the five years from 1976 to 1980, more than 500 papers on this question were published in various journals throughout the world and at least three major international discussions were held (see p. 17). The newness of the discussion of the topic stems from the qualitative reinterpretation of the physical essence of the phenomenon and its role in the ocean, particularly in the processes of mixing and structure formation. While in the past the conventional view of fronts as boundaries between large scale water masses of the ocean only led to the recognition of convenient classi fication limits created by nature itself, there is now a tendency to study oceanic fronts as integral elements of the dynamics of oceanic waters. As we understand it, fronts are being associated more and more with the dynamic and kinematic features which arise when kinetic energy and enstrophy are transmitted through a cascade of scales characterizing various forms of motion of a stratified medium in laterally confined oceanic basins. We are beginning to get a better understanding of the role synoptic-scale oceanic eddies play in the process of frontogenesis in the ocean.

This title presents the systematization and description of accumulated knowledge on oceanic fronts of the Norwegian, Greenland, Barents and Bering Seas. The main fronts of the Norwegian, Greenland and Barents Seas are part of the climatic North Polar Frontal Zone (NPFZ). The work is based on numerous observational data, collected by the authors during special sea experiments directed at the investigation of physical processes and phenomena inside certain parts of the NPFZ and in the northern part of the Bering Sea, on archive data of the USSR Hydrometeocenter and other research institutions, as well as on a wide scientific literature published in Russian and Western editions. The book contains general information on the oceanic fronts of the Subarctic Seas, brief history of their investigation, state of the knowledge, as well as detailed description of the thermohaline structure of all frontal zones in the Norwegian, Greenland, Barents and Bering Seas and of neighboring fronts of Arctic and coastal origin. Special attention is given to the study of the multifrontal character of the NPFZ and of peculiarities of its internal structure at different locations, to the description of diverse oceanic features observed in the NPFZ, as well as to some characteristics of the horizontal and vertical fine structure of hydrophysical fields in the NPFZ. The main features of the northern Bering Sea's summer ecohydrodynamics are investigated with the help of three-dimensional direct and inverse models.

This book is a unique and authoritative review of chemical fronts in the ocean world. It includes regional chapters on chemical fronts in all major oceans (Atlantic, Indian, Pacific, Arctic, and Southern) and marginal seas (North Sea, Baltic Sea, Mediterranean Sea, Gulf of Mexico, Yellow Sea, and the East Siberian Sea). Thematic chapters focus on diverse topics such as cross-frontal transfer of nutrients; diapycnal mixing and its impact on nutrient fluxes in western boundary currents (Gulf Stream and Kuroshio); front-driven physical-biogeochemical-ecological interactions; dynamics of coloured dissolved organic matter; pollutant concentration and fish contamination in frontal zones; distribution of microplastics in the ocean, and Lagrangian methods to study the transport of marine litter. This volume will appeal to a broad audience, including researchers, instructors, students, and practitioners of all kinds involved in scientific and applied research, environment protection and conservation, and maritime industries including fisheries, aquaculture, and mining. Chapter "Lagrangian Methods for Visualizing and Assessing Frontal Dynamics of Floating Marine Litter with a Focus on Tidal Basins" is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

This book reviews and summarizes the results and hypotheses raised by studies directly or indirectly dealing with the ecology of fronts and aims to identify the themes that connect them to produce a synthesis of this knowledge. Though not immediately perceived the ocean is highly structured and fronts are one of the most important components of its structural complexity. Marine fronts have been known since the early 20th Century, however, the more recent availability of high resolution satellite imagery, field measurements and numerical simulations have greatly advanced our understanding of their ecological impact. This work touches on topics such as front types, its biology and its comparisons with other bounderies at sea, as well as comparisons of fronts with terrestrial boundaries and the ‘ecotone’ concept. Furthermore, it also looks at the management and conservation of marine life.

The application of mesocosms, defined in this report as artificial 3 3 experimental enclosures ranging in size from 1 m to 10m , to address various problems in the marine sciences has been a relatively recent development. The application of the technology was dictated by the realization that many important ocean processes and interactions cannot be fully understood from observations in the natural environment or in smaller enclosures. Such studies involve, for example, determining the interactions between, and energy transfer from, one trophic level to another, the biogeochemical cycling of elements and compounds, etc. These and similar interactions and rate processes cannot normally be established in situations (nature) where the detection and quantification of rate processes are confused by advection and/or the inability to study the same populations over time. In the case of microcosms, mixed populations of primary producers, consumers, and carnivores cannot be maintained, in balance, for a sufficient length of time to determine normal interactions between the various components of these trophic levels. This report, prepared by SCOR Working Group 85, critically examines past applications of mesocosms to ocean research, though there is no attempt to comprehensively review all literature relevant to the subject. Further, the report outlines some important advances emanating from their use and provides recommendations for future applications. It constitutes the first of two reports from the Working Group (see Introduction).

This first volume in the treatise on the Physics of Lakes deals with the formulation of the mathematical and physical background. A large number of lakes on Earth are described, presenting their morphology as well as the causes of their response to the driving environment. Because the physics of lakes cannot be described without the language used in mathematics, these subjects are introduced first by using the simplest approach and with utmost care, assuming only a limited college knowledge of classical Newtonian physics, and continues with increasing complexity and elegance, starting with the fundamental equations of Lake Hydrodynamics in the form of ‘primitive equations’ and leading to a detailed treatment of angular momentum and vorticity. Following the presentation of these fundamentals turbulence modeling is introduced with Reynolds, Favre and other non-ergodic filters. The derivation of averaged field equations is presented with different closure schemes, including the k-ε model for a Boussinesq fluid and early anisotropic closure schemes. This is followed by expositions of surface gravity waves without rotation and an analysis of the role played by the distribution of mass within water bodies on the Earth, leading to a study of internal waves. The vertical structure of wind-induced currents in homogeneous and stratified waters and the Ekman theory and some of its extensions close this first volume of Physics of Lakes. The last chapter collects formulas for the phenomenological coefficients of water.
