Ocean Chemistry and Deep-sea Sediments by Open University Pdf

After a brief introduction to the distribution of deep-sea sediments, we show how the activities of marine organisms cycle nutrients and other dissolved constituents within the oceans, and influence the rates at which both solid and dissolved material is removed to sediments. Chapter 3 reviews the carbonate system and ends with a brief excursion into palaeoceanography. We conclude by describing the biological and chemical processes that continue long after sediments have been deposited on the deep-sea floor.

Methods for the Study of Deep-Sea Sediments, Their Functioning and Biodiversity by Roberto Danovaro Pdf

For years scientists viewed the deep sea as calm, quiet, and undisturbed, with marine species existing in an ecologically stable and uniform environment. Recent discoveries have completely transformed that understanding and the deep sea is recognized as a complicated and dynamic environment with a rich diversity of marine species. Carefully designed to provide practical information in an easily accessible format, Methods for the Study of Deep-Sea Sediments, Their Functioning, and Biodiversity covers how to investigate the biological components through analysis of their biodiversity. It also provides the protocols and methodological details needed to investigate some aspects of the functional biodiversity of variables commonly utilized to describe and understand the drivers of deep-sea ecosystem functioning. This volume contains detailed protocols for analyzing all benthic components from benthic viruses, prokaryotes, protozoa, foraminifera, to meio-, macro-, and megafauna. It includes step-by-step procedures, with additional notes on the crucial steps or possible difficulties arising from the analysis. Each chapter provides a brief introduction, a description of the sampling procedures and/or the sample treatment, and then the laboratory protocols, providing information on instrument setting and/or the solutions utilized. Each chapter also contains a visual scheme of the protocol for use during laboratory activities and for tracking each laboratory step. Linking information on biodiversity with the functioning of the marine ecosystems, the book covers all living components of the benthos. It provides practical information for anyone studying deep-sea habitats, their characteristics, functioning, and biodiversity.

Deep-Sea Sediments by Anton Inderbitzen Pdf

As part of its continuing program to stimulate superior basic research in the marine environment, the Office of Naval Research, Ocean Science and Technology Division, sponsored a series of closed seminar-workshops in 1972-1973. Each seminar focused upon one re search area of marine geology which is relatively new and in need of a critical evaluation and accelerated support. The subjects areas chosen for the seminars were: 1. natural gases in marine sediments and their mode of distribution, 2. nephelometry and the optical properties of ocean waters, 3. physical and engineering properties of deep-sea sediments, and 4. physics of sound in marine sediments. The objectives of each seminar-workshop were to bring into sharper focus the state-of-the-science within each subject area, to effect some degree of coordination among the investigators working within each of these areas and to provide the Ocean Science and Technology Division guidance for national program support. This volume.contains most of the papers presented at the semi nar on the physical and engineering properties of deep-sea sediments. The seminar was held at Airlie House, Airlie, Virginia on April 24- 27, 1973 and was organized and chaired by A. Inderbitzen. The at tendees were invited from among the leading investigators in this field from both the engineering and scientific disciplines. Each attendee was requested to prepare a paper within his area of spe ciality.

Geochemistry of Marine Sediments by David J. Burdige Pdf

The processes occurring in surface marine sediments have a profound effect on the local and global cycling of many elements. This graduate text presents the fundamentals of marine sediment geochemistry by examining the complex chemical, biological, and physical processes that contribute to the conversion of these sediments to rock, a process known as early diagenesis. Research over the past three decades has uncovered the fact that the oxidation of organic matter deposited in sediment acts as a causative agent for many early diagenetic changes. Summarizing and discussing these findings and providing a much-needed update to Robert Berner's Early Diagenesis: A Theoretical Approach, David J. Burdige describes the ways to quantify geochemical processes in marine sediment. By doing so, he offers a deeper understanding of the cycling of elements such as carbon, nitrogen, and phosphorus, along with important metals such as iron and manganese. No other book presents such an in-depth look at marine sediment geochemistry. Including the most up-to-date research, a complete survey of the subject, explanatory text, and the most recent mathematical formulations that have contributed to our greater understanding of early diagenesis, Geochemistry of Marine Sediments will interest graduate students of geology, geochemistry, and oceanography, as well as the broader community of earth scientists. It is poised to become the standard text on the subject for years to come.

Ocean Acidification by National Research Council,Division on Earth and Life Studies,Ocean Studies Board,Committee on the Development of an Integrated Science Strategy for Ocean Acidification Monitoring Pdf

The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Metalliferous Sediments of the World Ocean by Evgeny G. Gurvich Pdf

Dramatic advances in understanding global tectonics have been made in the last half century and the information and specific data acquired on the floor of the World Ocean by the scientific community probably has exc- ded that available in all previous time. With the benefit of new technology and advanced concepts in the earth sciences extensive exploration of the deep seabed became possible, and has been carried out in many parts of the world. Many features have been recognized and data recorded that are vital for understanding the fundamental processes that shape the earth=s surface and control the habitable environment. The data collected to date on the o- an floor and its physical environment greatly exceeds our understanding and appreciation of their fundamental importance in the earth sciences, and our ability to apply this knowledge effectively in improving our way of life. With his extensive scientific knowledge and unique experience from - ny cruises in association with scientists throughout the world, Dr. Evgeny Gurvich has made an outstanding contribution in acquiring basic data on hydrothermal and sedimentation processes in the ocean, as well as in the synthesis of data and concepts available from cruise reports and an extensive literature.

Ocean Acidification by Jean-Pierre Gattuso,Lina Hansson Pdf

The ocean helps moderate climate change thanks to its considerable capacity to store CO2, through the combined actions of ocean physics, chemistry, and biology. This storage capacity limits the amount of human-released CO2 remaining in the atmosphere. As CO2 reacts with seawater, it generates dramatic changes in carbonate chemistry, including decreases in pH and carbonate ions and an increase in bicarbonate ions. The consequences of this overall process, known as "ocean acidification", are raising concerns for the biological, ecological, and biogeochemical health of the world's oceans, as well as for the potential societal implications. This research level text is the first to synthesize the very latest understanding of the consequences of ocean acidification, with the intention of informing both future research agendas and marine management policy. A prestigious list of authors has been assembled, among them the coordinators of major national and international projects on ocean acidification.
