Download or read book From the Agulhas to the South Atlantic written by Deirdre Byrne and published by Universal-Publishers. This book was released on 2000-07-31 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Agulhas Retroflection transfers heat, salt and vorticity from the Indian Ocean to the South Atlantic. The transfer is accomplished by discrete meso-scale features and by the advection of a water column of mixed Atlantic and Indian Ocean origins. The objectives of this thesis are to measure the strength of the Agulhas-South Atlantic (ASA) exchange and to develop a generalized method for the measurement of mass and thermohaline fluxes. First, ASA mass and energy fluxes are estimated by using sea surface height (SSH) anomalies from satellite altimetry to monitor Agulhas eddies, a significant component of ASA transport. ~20 eddies are tracked from SSH during 1986 - 1989. Six eddies/year are observed entering the South Atlantic; when combined with information from hydrography this suggests minimum annual ASA mass and energy fluxes of O(5x10^6) m^3/s and O(10^17) J. Next, the accuracy of altimetric tide models, critical to measurements of ASA fluxes using altimetry, is evaluated in the Agulhas region by a comparison with in situ bottom pressure (BP). The CSR 3.0 model accounts for 98.5% - 99.4% of the variance in bottom pressure at four locations, with maximum discrepancies between model and in situ tides reaching 6.5 cm. In Enhanced Thermohaline Transport Analysis (ETTA), developed herein, vertically averaged thermohaline transport coefficients are parameterized as functions of SSH and acoustic travel time (tau). These quantities, which can be directly measured, are then used as proxies to determine mass and thermohaline fluxes from time-series of altimetric SSH and tau from inverted echo sounder moorings. Using ETTA, the 1992 - 1993 baroclinic-barotropic ASA fluxes through a moored array at 30S (2E - 17E) are estimated at O(14.5x10^6) m^3/s, O(15x10^20) J and O(83x10^12) kg salt per annum. Meso-scale eddies accomplish at least 18% of the transport. Lastly, ETTA is combined with the Gravest Empirical Mode (GEM) technique to create continuous parameterizations of temperature and salinity fields with pressure, tau and SSH. Thus tau and SSH become proxies for vertically resolved thermohaline profiles. With data from the Caribbean region, GEM-ETTA is shown to have the potential to resolve inter-ocean mass and thermohaline fluxes with time and depth.
Download or read book The South Atlantic written by Gerold Wefer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents results of recent projects in oceanography and marine geosciences (e.g. WOCE, JGOFS, PAGES, ODP) regarding present and past circulation in the South Atlantic. The objective of the book is to integrate results from both oceanographic and geological studies. As the connecting link between the Antarctic and the North Atlantic, the South Atlantic plays a crucial role with regard to the heat budget of the North Atlantic and to the biogeochemical budget of the global ocean. New results from studies of meridional water mass and heat transports are presented. The central theme of geological investigations is the reconstruction of current and productivity systems in the South Atlantic during the late Quaternary.

Book excerpt: The Agulhas Retroflection south of Africa lies at the junction of the S. Indian, S. Atlantic, and Circumpolar Oceans. A March 1985 survey, including hydrographic stations, subsurface current path survey, and contemporaneous sea surface temperature (SST) satellite infrared image, plus historical data, are used to characterize the region. In 1985, Agulhas transport was 56 to 95 Sv (1 million m/s; relative to 2400 dbar), up to 1.5 times the interior transport from linear theory and observed winds. Return Current transport was 54 and 65 Sv. The current retroflected in two branches. The surface warm core retroflected upstream of the second branch, while an SST front, and the subsurface current path survey, followed it. A cold ring, with 64 Sv transport but no SST anomaly, and a ware recirculation lay between the branches. Curvature vorticity at anticyclonic turns in the path exceeded the gradient wind maximum, so other dynamics must locally contribute. Salt, oxygen, and potential vorticity fronts on isopycnals in the current's upper approx. 300 m are observed, as are deep western boundary filaments of Red Sea Water and N. Atlantic Deep Water influences. The current meets baroclinic barotropic instability necessary conditions. Thermocline water (>8C) transport into the S. Atlantic is 2.8 to 9.6 Sv, less than the or = 10 Sv Atlantic export of deep water. Keywords: Agulhas currents, Oceanographic data; Optical data; Air water interactions; Western boundary current; Oceanographic fronts; Salinity; Ocean currents; Indian Ocean; South Atlantic Ocean.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the views of leading scientists on the knowledge of the global ocean circulation following the completion of the observational phase of the World Ocean Circulation Experiment. WOCE's in situ physical and chemical measurements together with satellite altimetry have produced a data set which provides for development of ocean and coupled ocean-atmosphere circulation models used for understanding ocean and climate variability and projecting climate change. This book guides the reader through the analysis, interpretation, modelling and synthesis of this data.

Available in PDF, EPUB and Kindle. Book excerpt: The book presents the most relevant research of the participants of the VII International Conference of Young Scientists "Complex Investigation of the World Ocean" (CIWO-2023). This conference was held at Saint Petersburg State University in May 15-19, 2023 (Saint Petersburg, Russia). It covers a wide range of fundamental and applied marine and limnology studies combined in eight sections: Ocean Physics, Ocean Biology, Ocean Chemistry, Marine Geology, Marine Geophysics, Marine Ecology and Environmental Management, Physical and Biological interactions (interdisciplinary section), Oceanological Technology and Instrumentation. The aim of this book is to show the relevance of the marine research due to the crucial role of the World Ocean in determining climate change on Earth, huge resources (fish resources, oil, gas and ore deposits, etc.) and intensive development of infrastructure in coastal and offshore zones. All these topics were marked within the framework of realization of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030). The studies presented in the book covers the wide spectrum of different the most important marine and limnology issues: thermohaline structure of water body and interactions between ocean and atmosphere, dynamic of the ocean, marine ice in polar regions, biodiversity of the marine ecosystems, adaptation of marine life to climate changes, geological and geophysical investigations in oil and gas regions, sedimentation, paleooceanology and biostratigraphy, hydrochemistry of estuary regions and carbon fluxes, microplastic pollution of the ocean, eutrophication and etc.
