Available in PDF, EPUB and Kindle. Book excerpt: The simulation of turbulent mixing processes in marine waters is one of the most pressing tasks in oceanography. It is rendered difficult by the various complex phenomena occurring in these waters like strong stratification, ex ternal and internal waves, wind generated turbulence, Langmuir circulation etc. The need for simulation methods is especially great in this area because the physical processes cannot be investigated in the laboratory. Tradition ally, empirical bulk type models were used in oceanography, which, however, cannot account for many of the complex physical phenomena occurring. In engineering, statistical turbulence models describing locally the turbulence mixing processes were introduced in the early seventies, such as the k E model which is still one of the most widely used models in Computational Fluid Dy namics. Soon after, turbulence models were applied more and more also in the atmospheric sciences, and here the k kL model of Mellor and Yamada became particularly popular. In oceanography, statistical turbulence mod els were introduced rather late, i. e. in the eighties, and mainly models were taken over from the fields mentioned above, with some adjustments to the problems occurring in marine waters. In the literature on turbulence model applications to oceanography problems controversial findings and claims are reported about the various models, creating also an uncertainty on how well the models work in marine water problems.

This book was released on 2012-03-29 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this exciting and innovative textbook, two leading oceanographers bring together the fundamental physics and biology of the coastal ocean in a quantitative but accessible way for undergraduate and graduate students. Shelf sea processes are comprehensively explained from first principles using an integrated approach to oceanography that helps build a clear understanding of how shelf sea physics underpins key biological processes in these environmentally sensitive regions. Using many observational and model examples, worked problems and software tools, the authors explain the range of physical controls on primary biological production and shelf sea ecosystems. Boxes throughout the book present extra detail for each topic and non-mathematical summary points are provided for physics sections, allowing students to develop an intuitive understanding. The book is fully supported by extensive online materials, including worked solutions to end-of-chapter exercises, additional homework/exam problems with solutions and simple MATLAB and FORTRAN models for running simulations.

Download or read book Diapycnal Advection by Double Diffusion and Turbulence in the Ocean written by Louis C. St. Laurent and published by . This book was released on 1999 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of double-diffusive mixing in the North Atlantic thermocline is considered. Mixing observations are analyzed in terms of the stability parameters for shear and double-diffusive convection, and a nondimensional ratio of dissipation rates. While the model for turbulence describes most dissipation occurring in high shear, dissipation in low shear is better described by the salt-finger model, and a method for estimating the salt-finger enhancement of the diapycnal haline diffusivity over the thermal diffusivity is proposed. These calculations suggest that salt-finger driven haline flux drives diapycnal downwelling in the upper thermocline. The role of turbulence occurring above rough bathymetry in the abyssal Brazil Basin is also considered. The mixing levels along sloping bathymetry exceed the levels observed on ridge crests and canyon floors. Additionally, mixing levels modulated in phase with the spring-neap tidal cycle. A model of the dissipation rate is derived and used to specify the turbulent mixing rate and constrain the diapycnal advection in an inverse model for the steady circulation. The inverse model solution reveals the presence of a secondary circulation with zonal character. These results suggest that mixing in abyssal canyons plays an important role in the mass budget of Antarctic Bottom Water.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a thorough treatment of both theoretical and observational aspects of the interaction between the sea-floor and the near-sea-floor dynamics; the effect this has on the distribution of internal and seabed stress; and the relevance of the associated dynamics to sedimentation processes. The theoretical work described involved both analytical and numerical modelling studies of a wide range of near-shore and shelf processes. These provide a valuable store of information on the interaction between the sea-floor and the dynamics of the overlying water. The book also includes an account of tidal analysis techniques and how these are being applied in the analysis of tidal current measurements. The observational studies relate to measurements of near-sea-floor turbulence and sand-transport in the littoral zone.

This book was released on 2024-08-26 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continued global warming and ocean acidification are predicted with high confidence, while the direction and magnitude of changes of other atmospheric drivers (e.g. precipitation, wind) and nutrient loading are of high uncertainty and regionally dependent. Biogeochemical responses of coastal shelf seas to external drivers are often nonlinear, involving feedback that may amplify or dampen a perturbation imposed on the system. Coupled physical-biogeochemical process-based numerical models have proven useful in elucidating the mechanistic interplay and relative importance of the different factors contributing to ecosystem functioning with increasing realism. This research topic aims to understand and compare marine ecosystem functioning in Chinese and European shelf seas, based on studies that use state-of-the-art modeling and monitoring of coastal ecosystem dynamics. This topic will enable more efficient knowledge share and distribution through a comparative assessment between distinct coastal shelf systems in China and Europe to further our understanding of complicated ecosystem dynamics in response to a changing climate and increasing anthropogenic pressure. It will allow us to better understand the sensitivity of coastal shelf ecosystem functioning to physical and biogeochemical perturbations, the role of shelf seas in global carbon cycling, and the resilience of Chinese and European shelf seas to ongoing and future changes in climate and anthropogenic activities.

Available in PDF, EPUB and Kindle. Book excerpt: Onshore penetration of oceanic water across the Antarctic continental slope (ACS) plays a major role in global sea level rise by delivering heat to the Antarctic marginal seas, thus contributing to the basal melting of ice shelves. We show that the time-mean and eddy components of the onshore Heat Transport (HT) around the Antarctic Continental Margin (ACM) in a global 0.1° coupled ocean-sea ice model add up to O(20 TW) in the annual average. The contributions from eddy advection, eddy stirring, and mean flow advection to the total onshore HT vary regionally. The time-mean component governs the seasonal variability of the total HT and largely cancels the eddy component. We examine the depth-integrated vorticity balance of this simulation to gain further insigth into the dynamics of these processes. Maps of the time-averaged depth-integrated vorticity budget terms and time series of the spatially-averaged, depth-integrated vorticity budget terms reveal that the flow in the Amundsen, Bellingshausen and Weddell Seas and in the western portion of East Antarctica, is closer to an approximate Topographic Sverdrup Balance compared to other segments of the ACM. This suggests that the surface-stress curl, imparted by the wind and the sea ice, has the potential to contribute to the meridional, approximately cross-slope, transport to a greater extent in some segments of the ACM than others. In the second part of this thesis, we describe the observed spatio-temporal variability and vertical structure of turbulent Reynolds stresses in a stratified mid-latitude inner-shelf with an energetic internal wave climate. We link the Reynolds stresses to different physical processes, namely internal bores, mid-water shear instabilities within vertical shear events related to wind-driven subtidal along-shelf currents; and non-turbulent stresses related to incoming Nonlinear Internal Wave (NLIW) trains. Among other conclusions, the results highlight that internal bores and shoaling NLIWs may also be important dynamical players in other inner-shelves with energetic internal waves. In the mesoscale, simulations and an along-isobath survey suggest that the balanced-to-unbalanced transition along the 50 m isobath is at 12-22 km, and that baroclinic instability of the subtidal along-shelf flow is a plausible explanation for the cross-shelf structure of the transition scale.
