Download or read book Jan Mayen Island in Scientific Focus written by Stig Skreslet and published by Springer Science & Business Media. This book was released on 2013-11-13 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jan Mayen is a volcanic island surrounded by the deep Greenland, Iceland and Norwegian Seas. There, atmospheric and oceanic processes unleash potential energy that forces very dynamic interactions between sea and air. This unique geophysical focal point generates climatic variability in northern Europe, and supports marine biological production that sustains the yield of large living resources. The marine populations are clearly fluctuating with variations in climate, and raises questions about effects of man-made climate change. Since the last Ice Age the sinking of Greenland Sea Deep-Water has been a substantial driving force for the Global Thermo-Haline Circulation which feeds warm Atlantic water into the Nordic Seas. Global warming may interact with the deep-water formation and force feedback mechanisms that express themselves beyond imagination. The book addresses such problems to raise an interest for doing research on the island and in its waters. The potentials for doing that increases when the island's Loran-C station closes down in 2005. The book recommends how the international scientific community may gain access to this really challenging arena for local, regional and Global research. It is a blueprint for the logistics required for science to succeed in a very remote and physically demanding place on Earth.

Download or read book Diel Vertical Migration of Zooplankton in Lakes and Oceans written by Joop Ringelberg and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover distances of 10–40 m in lakes or even a few hundred metres in the open oceans. Although not as spectacular as migrations of birds or the massive movements of large mammals over the African savannas, the numbers involved are very large and the biomass exceed the bulk of the African herds. For example, in the Antarctic oceans swarms of “Krill” may cover kilometres across, with thousands of individuals per cubic metre. These Euphausiids are food for whales, the most bulky animals on earth. Zooplankton are key species in the pelagic food web, intermediary between algae and ?sh, and thus essential for the functioning of the pelagic community. Prey for many, they have evolved diverse strategies of survival and DVM is the most imp- tant one. Most ?sh are visually hunting predators and need a high light intensity to detect the often transparent animals. By moving down, the well-lit surface layers are avoided but they have to come up again at night to feed on algae.
Download or read book Lipids in Aquatic Ecosystems written by Michael T. Arts and published by Springer Science & Business Media. This book was released on 2009-06-12 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evidence now suggests that the roles of essential fatty acids as growth promoters and as indices of health and nutrition are fundamentally similar in freshwater and marine ecosystems. Lipids in Aquatic Ecosystems integrates this divergent literature into a coordinated, digestible form. Chapters are organized so as to discuss and synthesize the flow of lipids from lower to higher trophic levels, up to and including humans. Linkages between the production, distribution and pathways of these essential compounds within the various levels of the aquatic food webs, and their ultimate uptake by humans and other terrestrial organisms, are highlighted throughout the book. This book will be of interest to researchers and resource managers working with aquatic ecosystems.

Download or read book The Biological Chemistry of Marine Copepods written by E. D. S. Corner and published by Oxford University Press, USA. This book was released on 1986 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological investigations of marine copepods have recently involved the use of chemical and biochemical techniques with increased frequency. The contributors to this collection of critical reviews provide a survey of the research projects already completed and draw attention to problems requiring further investigation. Beginning with a summary of basic chemical composition and energy content, subsequent chapters discuss lipids, enzymes involved in vital functions, and solid excretion's effects on the nitrogen and phosphorous cycles in the sea. Designed to meet a wide range of needs, this valuable sourcebook is the first to assemble and review the extensive literature on studies of this kind for marine biologists and ecologists, zoologists, comparative biochemists, oceanographers, insect physiologists, and geochemists.
Download or read book POLAR NIGHT Marine Ecology written by Jørgen Berge and published by Springer Nature. This book was released on 2020-04-08 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, the prevailing view of marine life at high latitudes has been that organisms enter a general resting state during the dark Polar Night and that the system only awakens with the return of the sun. Recent research, however, with coordinated, multidisciplinary field campaigns based on the high Arctic Archipelago of Svalbard, have provided a radical new perspective. Instead of a system in dormancy, a new perspective of a system in full operation and with high levels of activity across all major phyla is emerging. Examples of such activities and processes include: Active marine organisms at sea surface, water column and the sea-floor. At surface we find active foraging in seabirds and fish, in the water column we find a high biodiversity and activity of zooplankton and larvae such as active light induced synchronized diurnal vertical migration, and at seafloor there is a high biodiversity in benthic animals and macroalgae. The Polar Night is a period for reproduction in many benthic and pelagic taxa, mass occurrence of ghost shrimps (Caprellides), high abundance of Ctenophores, physiological evidence of micro- and macroalgal cells that are ready to utilize the first rays of light when they appear, deep water fishes found at water surface in the Polar night, and continuous growth of bivalves throughout the winter. These findings not only begin to shape a new paradigm for marine winter ecology in the high Arctic, but also provide conclusive evidence for a top-down controlled system in which primary production levels are close to zero. In an era of environmental change that is accelerated at high latitudes, we believe that this new insight is likely to strongly impact how the scientific community views the high latitude marine ecosystem. Despite the overwhelming darkness, the main environmental variable affecting marine organisms in the Polar Night is in fact light. The light regime during the Polar Night is unique with respect to light intensity, spectral composition of light and photoperiod.
