Hydrogeochemistry of Aquatic Ecosystems Discover the geological
foundation of global water supply, focusing on resource
conservation and restoration Hydrogeochemistry explores the
connections between the geology of a region and the chemical
characteristics and quality of its water sources, including such
factors as erosion, evaporation, and, increasingly, man-made
activities. With the emergence of climate change as a major factor
reshaping water quality and availability, the need to understand
interactions between hydrochemistry and geology has never been
greater. Hydrogeochemistry of Aquatic Ecosystems meets this need by
offering foundational knowledge about the hydrochemistry of
different types of aquatic systems, the nature of their
interactions with various pollutants and geological processes, and
the possibilities and dangers of human intervention. With a
particular focus on aqueous resource conservation and restoration,
this is a vital, timely guide to a potentially life-saving subject.
Hydrogeochemistry of Aquatic Ecosystems readers will also find:
Detailed treatment of water-sediment interactions, arsenic and
fluoride enrichment, sand mining, and many other subjects Coverage
throughout of solute acquisition processes, the carbon cycle, and
nutrient geochemistry Case studies from Asia and Africa
demonstrating both natural and anthropogenic hydrogeochemical
interactions Hydrogeochemistry of Aquatic Ecosystems is
indispensable for professionals and researchers in environmental
science and environmental engineering, as well as scholars and
advanced graduate students working on aquatic ecosystems or effects
of climate change.
Coastal Wetlands, Second Edition: An Integrated and Ecosystem
Approach provides an understanding of the functioning of coastal
ecosystems and the ecological services that they provide. As
coastal wetlands are under a great deal of pressure from the dual
forces of rising sea levels and the intervention of human
populations, both along the estuary and in the river catchment,
this book covers important issues, such as the destruction or
degradation of wetlands from land reclamation and infrastructures,
impacts from the discharge of pollutants, changes in river flows
and sediment supplies, land clearing, and dam operations.
Marine Pollution: Sources, Fate and Effects of Pollutants in
Coastal Ecosystems bring together the theoretical background on
common and emerging marine pollutants and their effects on
organisms (ecotoxicology). Written by a renowned expert in the
field who is a researcher, teacher and advisor of national and
international institutions on issues such as oil spills, water
quality assessment and plastic pollution, this book offers a
thorough account of the effects of pollutants on marine organisms,
the relevant environmental regulations, and the public health
implications, along with the biological tools advocated by the
international institutions for marine pollution monitoring. Marine
Pollution: Sources, Fate and Effects of Pollutants in Coastal
Ecosystems presents information in a detailed and didactic manner,
reviewing the latest scientific knowledge alongside examples of
practical applications.
Pollution due to various anthropogenic activities continues to
increase. In terms of water pollutants, organic and inorganic
pollutants are the most problematic. Although several measures have
been proposed and implemented to prevent or reduce contamination,
their increased concentration in water bodies has created serious
concerns. Over the years, the problem has been aggravated by
industrialization, urbanization and the exploitation of natural
resources. The direct discharge of wastewater contaminants and
their geographical mobilization have caused an increase in
concentration in ground, surface, fluvial and residual waters.
Extensive information about detection and disposal methods is
needed in order to develop technological solutions for a -variety
of environments, both urban and rural. This book provides
up-to-date information on wastewater contaminants, aimed at
researchers, engineers and technologists working in this field.
Conventional physicochemical techniques used to remove contaminants
from wastewater include ion exchange, precipitation, degradation,
coagulation, coating, membrane processes and adsorption. However,
these applications have technological and economic limitations, and
involve the release of large amounts of chemical reagents and
by-products that are themselves difficult to remove. Biosorption -
the use of organically generated material as an adsorbent - is
attracting new research and scholarship. Thermally-treated calcined
biomaterials may be treated to remove heavy metals from wastewater.
To ensure the elimination of these contaminants, existing solutions
must be integrated with intelligent biosorption functions.
Biosorption for Wastewater Contaminants will find an appreciative
audience among academics and postgraduates working in the fields of
environmental biotechnology, environmental engineering, wastewater
treatment technology and environmental chemistry.
Investigating Seafloors and Oceans: From Mud Volcanoes to Giant
Squid offers a bottom-to-top tour of the world's oceans, exposing
the secrets hidden therein from a variety of scientific
perspectives. Opening with a discussion of the earth's formation,
hot spots, ridges, plate tectonics, submarine trenches, and cold
seeps, the text goes on to address such topics as the role of
oceans in the origin of life, tidal bore, thermal effects,
ecosystem services, marine creatures, and nutraceutical and
pharmaceutical resources. This unique reference provides insight
into a wide array of questions that researchers continue to ask
about the vast study of oceans and the seafloor. It is a
one-of-a-kind examination of oceans that offers important
perspectives for researchers, practitioners, and academics in all
marine-related fields.
Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of
the Niger Delta is available just as exploration and production
activities are moving into the little known deep water terrain of
the Niger Delta. A thorough understanding of the Cenozoic Niger
Delta will improve understanding and exploration of the evolution
of deeper offshore belts, help researchers strengthen and refine
existing Neogene nannofossil biostratigraphic schemes for the Niger
Delta region, and gain a better understanding of the relationship
between nannofossil assemblage variations and paleoenvironments.
The hydrocarbon reserves of the Niger Delta are an extremely
valuable natural resource. Biostratigraphy and Correlation play
important roles in the discovery, development and maturing of
hydrocarbon fields. Calcareous nannofossils have been important
tools for the stratigraphers in the Niger Delta and in recent years
exploration has moved into deeper offshore areas where nannofossils
are more abundant and diverse. Little has been published about the
calcareous nannofossil chronostratigraphy of the Niger delta.
Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of
the Niger Delta fills the gap for earth scientists and those
working in the oil and gas industry.
A derivative of the Encyclopedia of Inland Waters, Biogeochemistry
of Inland Waters examines the transformation, flux and cycling of
chemical compounds in aquatic and terrestrial ecosystems, combining
aspects of biology, ecology, geology, and chemistry. Because the
articles are drawn from an encyclopedia, they are easily accessible
to interested members of the public, such as conservationists and
environmental decision makers.
The continental hydrological cycle is one of the least understood
components of the climate system. The understanding of the
different processes involved is important in the fields of
hydrology and meteorology. In this volume the main applications for
continental hydrology are presented, including the characterization
of the states of continental surfaces (water state, snow cover,
etc.) using active and passive remote sensing, monitoring the
Antarctic ice sheet and land water surface heights using radar
altimetry, the characterization of redistributions of water masses
using the GRACE mission, the potential of GNSS-R technology in
hydrology, and remote sensing data assimilation in hydrological
models. This book, part of a set of six volumes, has been produced
by scientists who are internationally renowned in their fields. It
is addressed to students (engineers, Masters, PhD) , engineers and
scientists, specialists in remote sensing applied to hydrology.
Through this pedagogical work, the authors contribute to breaking
down the barriers that hinder the use of Earth observation data.
Mountain Ice and Water: Investigations of the Hydrologic Cycle in
Alpine Environments is a new volume of papers reviewed and edited
by John Shroder, Emeritus Professor of Geography and Geology at the
University of Nebraska at Omaha, USA, and Greg Greenwood, Director
of the Mountain Research Initiative from Bern, Switzerland.
Chapters in this book were derived from research papers that were
delivered at the Perth III Conference on Mountains of our Future
Earth in Scotland in October 2015. The conference was established
to help develop the knowledge necessary to respond effectively to
the risks and opportunities of global environmental change and to
support transformations toward global sustainability in the coming
decades. To this end, the conference and book have investigated the
future situation in mountains from three points of view. (1)
Dynamic Planet: Observing, explaining, understanding, and
projecting Earth, environmental, and societal system trends,
drivers, and processes and their interactions to anticipate global
thresholds and risks, (2) Global Sustainable Development:
Increasing knowledge for sustainable, secure, and fair stewardship
of biodiversity, food, water, health, energy, materials, and other
ecosystem services, and (3) Transformations towards Sustainability:
Understanding transformation processes and options, assessing how
these relate to human values, emerging technologies and social and
economic development pathways, and evaluating strategies for
governing and managing the global environment across sectors and
scales.
