Ecosystems of the benthic environment are a sensitive index toecological change, and as such demand long-term and effectivemonitoring. Methods for the Study of Marine Benthos providescomprehensive information on the tools and techniques available tothose working in areas where the declining health of the sea,depletion of marine resources and the biodiversity of marine lifeare major concerns. In response to the need for increasingly detailed information onbottom-living communities, this fully revised new editionoffers: Contributions from a broad range of internationally recognisedexperts New information for those compiling environmental impactstatements, pollution assessments and working with eco-systemmanagement Two separate chapters on Imaging Techniques and DivingSystems A vital tool for all marine and environmental scientists,ecologists, fisheries workers and oceanographers, libraries in alluniversities and research establishments where these subjects arestudied and taught will find this book a valuable addition to theirshelves.
Rex and Etter present the first synthesis of patterns and causes of biodiversity in organisms that dwell in the vast sediment ecosystem of ocean floor. They offer a new understanding of marine biodiversity that will be of general interest to ecologists and is crucial to responsible exploitation of natural resources at the deep-sea floor.
The biological composition and richness of most of the Earth's major ecosystems are being dramatically and irreversibly transformed by anthropogenic activity. Yet, despite the vast areal extent of our oceans, the mainstay of research to-date in the biodiversity-ecosystem functioning arena has been weighted towards ecological observations and experimentation in terrestrial plant and soil systems. This book provides a framework for extending these concepts to a variety of marine systems. Marine Biodiversity and Ecosystem Functioning is the first book to address the latest advances in biodiversity-function science using marine examples. It brings together contributions from the leading scientists in the field to provide an in-depth evaluation of the science, before offering a perspective on future research directions for some of the most pressing environmental issues facing society today and in the future.
An up-to-date atlas of an important fossil and living group, with the Natural History Museum. Deep-sea benthic foraminifera have played a central role in biostratigraphic, paleoecological, and paleoceanographical research for over a century. These single–celled marine protists are important because of their geographic ubiquity, distinction morphologies and rapid evolutionary rates, their abundance and diversity deep–sea sediments, and because of their utility as indicators of environmental conditions both at and below the sediment–water interface. In addition, stable isotopic data obtained from deep–sea benthic foraminiferal tests provide paleoceanographers with environmental information that is proving to be of major significance in studies of global climatic change. This work collects together, for the first time, new morphological descriptions, taxonomic placements, stratigraphic occurrence data, geographical distribution summaries, and palaeoecological information, along with state-of-the-art colour photomicrographs (most taken in reflected light, just as you would see them using light microscopy), of 300 common deep-sea benthic foraminifera species spanning the interval from Jurassic - Recent. This volume is intended as a reference and research resource for post-graduate students in micropalaeontology, geological professionals (stratigraphers, paleontologists, paleoecologists, palaeoceanographers), taxonomists, and evolutionary (paleo)biologists.
This publication narrates the voyages of the iconic Norwegian research ship and documents marine research in the Western Indian Ocean, from early exploratory surveys to the current ecosystem surveys undertaken to support fisheries management. It provides a rare glimpse into the realities of conducting research at sea and evaluates the impact of the Nansen programme.
This United Nations report examines the current state of knowledge of the world's oceans, for policymakers, and provides a reference for marine science courses.
