This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the intensification of research activities in the Southern Ocean in recent years, both at national levels and through international cooperation in such projects as BIOMASS with its FIBEX and SIBEX phases, the need was felt increasingly for closer collaboration between biologists, meteorologists, and oceanographers in the study of the interaction between the atmospheric forces, the water masses, and the living resources. Better knowledge in this regard is not only of scientific interest but also of practical importance, especially for the management of the resources and the protection of the Antarctic marine ecosystem. As a follow-up on a recommendation by the IOC Program Group for the Southern Oceans made in March 1983, the Intergovernmental Oceanographic Commission organized a meeting of experts on oceanography related to the dynamics of the Antarctic ecosystems. During this meeting, held in Kiel, Federal Republic of Ger many, in May 1984, biologists and oceanographers involved in BIOMASS activities met with the oceanographers of SCOR Working Group 74 to discuss ways and means for additional physical and chemical observations in the oceanographic research within BIOMASS. It was the time when large fluctuations in the distribution of krill with subsequent detrimental effects on predator species dependent on krill had just been observed, and the question arose whether this was possibly the result of changes in the Antarctic water circulation.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antarctic Circumpolar Current (ACC) and the Southern Ocean meridional overturning circulation are dynamically linked through interactions between the mean flow, eddies, and mixing by breaking internal lee waves over rough topography. However, quantifying the time-mean and the spatio-temporal variability of the ACC transport, eddy fluxes, and small-scale mixing remains challenging as observations are scarce. This thesis work analyzes the mean eddy heat flux, finescale internal-wave-driven turbulence, and transport of the ACC in Drake Passage, and it examines the possible physical processes driving the spatial and temporal variability of these quantities. First, the eddy heat flux as a function of ACC streamlines is quantified using a unique 20-year time series of upper ocean temperature and velocity transects with unprecedented horizontal resolution. Using the time-varying streamlines, the across-ACC eddy heat flux is maximum poleward in the south flank of the Subantarctic Front and it reduces towards the south, becoming statistically insignificant in the Polar Front. These results indicate heat convergence south of the Subantarctic Front. Second, a unique four-year time series of stratification and near-bottom currents, and finestructure density and velocity profiles were employed to estimate the expected linear lee-wave energy and infer turbulent dissipation due to breaking internal waves. In contrast to idealized numerical predictions of 50% local dissipation of lee-wave energy, less than 10% dissipated locally regardless of the abyssal hill topographic representation. Third, the high-spatial-resolution time series of temperature, salinity, and velocity are used to identify trends in the Drake Passage total and geostrophic transport in the upper kilometer. We uniquely found that the Subantarctic Front and Polar Front, the two major ACC fronts, have significantly accelerated during the last decade whereas the area between these fronts and between the Polar Front and the Southern ACC Front has decelerated. These opposite trends compensate such that no significant trend is discernible in the total and geostrophic transport integrated across Drake Passage. We suggest the acceleration of the fronts is driven by an increase in the eddy activity in between the fronts.
Download or read book Satellite Altimetry for Earth Sciences written by Frédéric Frappart and published by MDPI. This book was released on 2019-04-09 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Satellite altimetry is a radar technique for measuring the topography of the Earth’s surface. It was initially designed for measuring the ocean’s topography, with reference to an ellipsoid, and for the determination of the marine geoid. Satellite altimetry has provided extremely valuable information on ocean science (e.g., circulation surface geostrophic currents, eddy structures, wave heights, and the propagation of oceanic Kelvin and Rossby waves). With more than 25 years of observations, it is also becoming vital to climate research, providing accurate measurements of sea level variations from regional to global scales. Altimetry has also demonstrated a strong potential for geophysical, cryospheric, and hydrological research and is now commonly used for the monitoring of Arctic and Antarctic ice sheet topography and of terrestrial surface water levels. This book aims to present reviews and recent advances of general interest in the use of radar altimetry in Earth sciences. Manuscripts are related to any aspect of radar altimetry technique or geophysical applications. We also encourage manuscripts resulting from the application of new altimetric technology (SAR, SARin, and Ka band) and improvements expected from missions to be launched in the near future (i.e., SWOT).
Download or read book Decadal Climate Variability written by David L.T. Anderson and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: On decadal time scales, climate change may result not only from man-made causes, but also from natural processes. This book brings together theoretical conceptions of the physical mechanisms of climate change with observational evidence of these changes. The following key topics are included: Observed Climatic Variability, Predictability of the Atmosphere and Oceans from Days to Decades, and Mechanisms for Decadal to Centennial Climate Variability. Further, there are specialised contributions on the role of the oceanic circulation in climate change. The authors are renowned for their pedagogical skills, and the book is primarily designed for beginners in the field, who have a background in physical science. In addition, it is an invaluable source of information for scientists seeking an overview on climate dynamics.

Download or read book Natural Climate Variability on Decade to Century Time Scales written by National Research Council and published by National Academies Press. This book was released on 1996-08-30 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reflects the current state of scientific knowledge about natural climate variability on decade-to-century time scales. It covers a wide range of relevant subjects, including the characteristics of the atmosphere and ocean environments as well as the methods used to describe and analyze them, such as proxy data and numerical models. They clearly demonstrate the range, persistence, and magnitude of climate variability as represented by many different indicators. Not only do natural climate variations have important socioeconomic effects, but they must be better understood before possible anthropogenic effects (from greenhouse gas emissions, for instance) can be evaluated. A topical essay introduces each of the disciplines represented, providing the nonscientist with a perspective on the field and linking the papers to the larger issues in climate research. In its conclusions section, the book evaluates progress in the different areas and makes recommendations for the direction and conduct of future climate research. This book, while consisting of technical papers, is also accessible to the interested layperson.

Available in PDF, EPUB and Kindle. Book excerpt: This important book, written by recognized leaders in their fields, discusses agricultural dimensions of global climate change. Research and policy issues are covered and a multidisciplinary view of global climate change and agriculture is presented. Major sections cover the contribution of agriculture to greenhouse gas (GHG) emissions (including an investigation as to whether monitoring and verification of such emissions would work) and the impact of global climate change on agriculture. The book examines such important issues as global food availability, distributional effects between developing and developed countries, agricultural adaptation possibilities, and whether CO2 enrichment will benefit agriculture. A unique feature of this publication is that it addresses communication difficulties between researchers and policy makers and suggests solutions.
