Download and read online ebook Ecosystems of the Deep Oceans write by P.A. Tyler. This book was released on 2003-03-27. Ecosystems of the Deep Oceans available in PDF, EPUB and Kindle. This volume examines the deep sea ecosystem from a variety of perspectives. The initial chapters examine the deep-sea floor, the deep pelagic environment and the more specialised chemosynthetic environments of hydrothermal vents and cold seeps. These environments are examined from the perspective of the relationship of deep-sea animals to their physico-chemical environment. Later chapters examine the biogeography of the main deep oceans (Atlantic, Pacific and Indian) with particular attention to the downward flux of surface-derived organic matter and how this drives the processes within the deep-sea ecosystem. The peripheral deep seas including the polar seas and the marginal deep seas (inter alia the Mediterranean, Red, Caribbean and Okhotsk seas) are explored in the same context. The final chapters examine the processes occurring in the deep sea and include an analysis of why the deep sea has high species diversity, how the fauna respond to organic input and how species have adapted reproductive activity in the deep sea. The volume concludes with an analysis of the anthropogenic impact on the deep sea.

Download and read online ebook Deep-Sea Ecosystems Off Mauritania write by Ana Ramos. This book was released on 2017-09-25. Deep-Sea Ecosystems Off Mauritania available in PDF, EPUB and Kindle. This book compiles the main findings of the multidisciplinary long-term research program developed in the continental margin of one of the more productive and unknown areas of the world oceans, Northwest Africa. The more than 25,000 preserved fishes and benthic invertebrates and quantitative data collected in 342 trawling stations, the 267 oceanographic profiles, the 211 sediment samples and the 28,122 km2 prospected by multi˗beam echo sounding allowed to obtain an overview of the amazing biodiversity of the demersal and benthic fauna inhabiting soft- and hard-bottom habitats, as well as the fascinating geomorphology and oceanography, hidden in the Mauritanian slope.

Download and read online ebook The Law of the Seabed write by Catherine Banet. This book was released on 2020-01-29. The Law of the Seabed available in PDF, EPUB and Kindle. The Law of the Seabed reviews the most pressing legal questions raised by the use and protection of natural resources on and underneath the world’s seabeds. While barely accessible, the seabed plays a major role in the Earth’s ecological balance. It is both a medium and a resource, and is central to the blue economy. New uses and new knowledge about seabed ecosystems, and the risks of disputes due to competing interests, urge reflection on which regulatory approaches to pursue. The regulation of ocean activities is essentially sector-based, and the book puts in parallel the international and national regimes for seabed mining, oil and gas, energy generation, bottom fisheries, marine genetic resources, carbon sequestration and maritime security operations, both within and beyond the national jurisdiction. The book contains seven parts respectively addressing the definition of the seabed from a multidisciplinary perspective, the principles of jurisdiction delimitation under the United Nations Convention on the Law of the Sea (UNCLOS), the regimes for use of non-living, living and marine biodiversity resources, the role of state and non-state actors, the laying and removal of installations, the principles for sustainable and equitable use (common heritage of mankind, precaution, benefit sharing), and management tools to ensure coexistence between activities as well as the protection of the marine environment.
Ecosystems and Biodiversity in Deep Waters and High Seas

Download and read online ebook Ecosystems and Biodiversity in Deep Waters and High Seas write by Kristina M. Gjerde. This book was released on 2006. Ecosystems and Biodiversity in Deep Waters and High Seas available in PDF, EPUB and Kindle. Ecosystems and Biodiversity in Deep Waters and High Seas outlines a number of options for the conservation and sustainable management of the deep seas and open oceans, including actions and measures that reflect an integrated approach to oceans management based on "ecological boundaries" rather than just political ones, giving higher levels of protection to vulnerable species like deep sea fish as well as to biologically and ecologically significant ecosystems such as cold water corals and hydrothermal vent communities.

Download and read online ebook Ocean Acidification write by National Research Council. This book was released on 2010-09-14. Ocean Acidification available in PDF, EPUB and Kindle. 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.
