Oceans and the Atmospheric Carbon Content, presents an
interdisciplinary overview of the role of the oceans as a carbon
sink and its relation with pH increasing trends and climate change.
This volume discusses topics such as: climate variability during
the last deglaciation, based on a high-resolution pollen analysis;
the potential impact of CO2 from large metropolitan areas over the
adjacent coastal zones and the importance of having high resolution
atmospheric CO2 data to estimate accurately air-sea CO2 exchanges;
present- day CO2 fluxes in the coastal ocean and their potential
feedbacks under global climate change; phytoplankton community
responses to climate change with emphasis on decreasing pH trends
in sea water and its ecological effects; pH decrease and its
effects on sea-water chemistry from a ten year time-series; the
effect of acidification on metal bioaccumulation; the effects of
increasing temperatures and acidification on contaminant dynamics
and availability to biota; the prevention of potential
environmental impacts related to the geological sequestration of
CO2. The book provides an updated synthesis of current concerns
related to global change trends in the oceans with a strong
emphasis on acidification. The content draws attention to the
importance of dealing with observed global change trends and their
effects upon the oceans using an interdisciplinary approach due to
their complexity and interlinks between different areas of
knowledge.

" ... as soon as one has traversed the greater part of the wild
sea, one comes upon such a huge quantity of ice that nowhere in the
whole world has the like been known." "This ice is of a wonderful
nature. It lies at times quite still, as one would expect, with
openings or large fjords in it; but sometimes its movement is so
strong and rapid as to equal that of a ship running before the
wind, and it drifts against the wind as often as with it."
Kongespeilet - 1250 A.D. ("The Mirror of Kings") Modern societies
require increasing amounts influence on the water mass and on the
resulting of scientific information about the environment total
environment of the region; therefore, cer tain of its
characteristics will necessarily be in whieh they live and work.
For the seas this information must describe the air above the sea,
included."
This book furthers academic scholarship in cutting-edge areas of
geographical and geopolitical writing by drawing on a series of
little-studied undersea living projects conducted by the US Navy
during the Cold War (Project Genesis, Sealab I, II and III).
Supported by an engaging and novel empirical setting, the central
themes of the book revolve around the practice and construct of
'territory', 'terrain', the 'elemental' and the interrelationships
between these material phenomenon and both human and non-human
bodies. Furthermore, the book will point to future research
trajectories in the form of 'extreme geographies' to better
understand living practices in a world that is increasingly
submerged and extreme.
Seagrasses are becoming widely used as in situ indicators of the relative health and condition of subtropical and tropical estuarine ecosystems. To permit meaningful management of our estuaries, there is clearly a need to develop and refine ways of effectively monitoring and assessing seagrasses. Seagrasses: Monitoring, Ecology, Physiology, and Management includes the peer-reviewed, written results of presentations made at a recent workshop that addressed this very issue. A total of 28 original research and review chapters are organized around four major themes: Ecology and Physiology, Monitoring and Trends, Management, and Restoration. Additional research study results, not completed at the time of the workshop, are also included as they are directly related to the topic of seagrass management ecology. Overall, Seagrasses: Monitoring, Ecology, Physiology, and Management encompasses the latest research in seagrass management ecology to assist in the promotion of a dialogue between the research and environmental management communities. Not only will this work serve as a cornerstone for continued improvement in effectively monitoring the health and condition of near coastal waters, but also as a reference central to the premise that effective and efficient assessment of seagrasses will aid in estuarine ecosystem management.
This open access book introduces the major environmental green
development issues from six major themes carbon neutrality,
nature-based solution, watershed management and climate adaptation,
BRI green development, sustainable food supply chain,
ecosystem-based integrated ocean management focusing on the
progress of China’s environment and development policies from
2021 accomplishments. It is based on the research outputs of CCICED
in the year of 2021, which marks China’s start point of
implementation of its 14th Five-Year Plan when world economy also
strived to recover from the pandemic. Â
Thisbookfocusesonthedynamicsoftheoceanbeingin?uencedbytheEarth'sro-
tion and density strati?cation. Fluids in motion are a dif?cult
subject of study that traditionally requires advanced knowledge of
analytical mathematics, in particularly matrix algebra,
differential and integral calculus, and complex analysis. Hence,
this fascinating ?eld of science, known as geophysical ?uid
dynamics, is accessible only to a limited number of students -
those who either are naturally geniuses or those who underwent
tough years of intense University study. Fluid processes are
inherently complex and analytical solutions describing ?uid
dynamics exist only in a few instances and only under highly
simpli?ed assu- tions. Computer-based numerical models are required
to approximate ?uid beh- ior in more realistic situations. Because
of its complexity, universities tend to offer subjects in
computational modelling of ?uid dynamics only at postgraduate
level. This is a pity given that ?uid processes are truly
fascinating in nature and given that the oceans play a signi?cant
role in shaping life on Earth. The approach I pursue in this book
is different from the traditional approach.
This open access book is based on the research outputs of China
Council for International Cooperation on Environment and
Development (CCICED) in 2021. It covers major topics of Chinese and
international attention regarding green development, such as
climate, biodiversity, ocean, BRI, urbanization, sustainable
production and consumption, technology, finance, value chain, and
related topics. It also reviews the progress of China‘s
environmental and development policies and the impacts from CCICED.
This is a highly informative and carefully presented book,
providing insight for policy makers in environmental issues.
The realism of large scale numerical ocean models has improved dra
matically in recent years, in part because modern computers permit
a more faithful representation of the differential equations by
their algebraic analogs. Equally significant, if not more so, has
been the improved under standing of physical processes on space and
time scales smaller than those that can be represented in such
models. Today, some of the most challeng ing issues remaining in
ocean modeling are associated with parameterizing the effects of
these high-frequency, small-space scale processes. Accurate
parameterizations are especially needed in long term integrations
of coarse resolution ocean models that are designed to understand
the ocean vari ability within the climate system on seasonal to
decadal time scales. Traditionally, parameterizations of
subgrid-scale, high-frequency mo tions in ocean modeling have been
based on simple formulations, such as the Reynolds decomposition
with constant diffusivity values. Until recently, modelers were
concerned with first order issues such as a correct represen tation
of the basic features of the ocean circulation. As the numerical
simu lations become better and less dependent on the discretization
choices, the focus is turning to the physics of the needed
parameterizations and their numerical implementation. At the
present time, the success of any large scale numerical simulation
is directly dependent upon the choices that are made for the
parameterization of various subgrid processes.
Observational and numerical modelling studies of the hydrodynamics,
sediment transport, and light extinction were undertaken in the
marine environment around Cape Bolinao in the Lingayen Gulf (NW
Philippines). This text reports on the results of these studies,
and offers conclusions.
Because of its centrallocation in the Old World, the Adriatic Sea
has long been explored and studied. Modern methods of
investigation, however, have accelerated the pace of study during
the last decade. These are the ADCP currentmeter, satellite
imagery, drifter technology, and, last but not least, the computer
with its arsenal of tools for data analysis and model simulations.
As a result of this renaissance, the Adriatic Sea and its
sub-basins are currently the object of intensified scrutiny by a
number of scientific teams, in Europe and be yond. Questions
concerning the mesoscale variability that dominates regional
motions, the seasonal circulation of the sea, and its long-term
climatic role in the broader Mediterranean, have become topics of
lively discussions. The time was ripe then when an international
workshop dedicated to the physical oceanography of the Adriatic Sea
was convened in Trieste on 21-25 September 1998. Its objectives
were to assess the current knowledge of the oceanography of the
Adriatic Sea, to review the newly acquired observations, to create
syn ergy between model simulations and observations, and to
identify directions for future Adriatic oceanography. This book,
however,is not the mere proceedings of the workshop. It was written
as a monograph synthetizing the current knowledge of the physical
oceanography of the Adriatic Sea, with the hope that it will serve
as a reference to anyone interested in the Adriatic. The book also
identifies topics in need of additional inquiry and proposes
research directions for the next decade.
This work addresses the whole range of problems relating to the
application of satellite technology to studies of regional seas and
sea phenomona - the Gulf Stream, the Kuroshia Current - and coastal
zones. It argues that to emphasize global applications is to fail
to take into account fundamental idiosyncracies specific to the
regional perspective. In addition, it describes implementation
techniques - data gathering; in situ data assurance, algorithms for
parameter retrieval; data storage; and data output.; The book
contains satellite imagery and incorporates case studies from areas
such as the Baltic and the Black Sea.
Dead-Reckoning aided with Doppler velocity measurement has been the
most common method for underwater navigation for small vehicles.
Unfortunately DR requires frequent position recalibrations and
underwater vehicle navigation systems are limited to periodic
position update when they surface. Finally standard Global
Positioning System (GPS) receivers are unable to provide the rate
or precision required when used on a small vessel. To overcome
this, a low cost high rate motion measurement system for an
Unmanned Surface Vehicle (USV) with underwater and oceanographic
purposes is proposed. The proposed onboard system for the USV
consists of an Inertial Measurement Unit (IMU) with accelerometers
and rate gyros, a GPS receiver, a flux-gate compass, a roll and
tilt sensor and an ADCP. Interfacing all the sensors proved rather
challenging because of their different characteristics. The
proposed data fusion technique integrates the sensors and develops
an embeddable software package, using real time data fusion
methods, for a USV to aid in navigation and control as well as
controlling an onboard Acoustic Doppler Current Profiler (ADCP).
While ADCPs non-intrusively measure water flow, the vessel motion
needs to be removed to analyze the data and the system developed
provides the motion measurements and processing to accomplish this
task.
The development of ocean sensors remains a ripe area for future
investigation from science, policy and systemsengineering
standpoints. Clearly, there are many options forrealizing
integrated molecular analytical sensing systems. The definition of
key target molecules, detection methodsand signal transduction
models largely remain to be determined.Moreover, there remains
ahuge challenge of merging this new class of instrument with
different deployment platforms, and supplying necessarypower and
data telemetry infrastructure for their operation. Molecular
Biological Technologies for Ocean Sensing features methods papers
on the application of ecogenomic sensors on autonomous platforms in
the ocean. Topics include the use of ecogenomic sensors as a tool
in whole-cell and cell-free based detection and monitoring a suite
of pathogens and biotoxins that are of public health concern;
documenting species diversity, evolution and metabolic function;
identification and quantification of aquatic organisms; and
inferring metabolic potential and activities of microorganisms in
the ocean. Each contribution focuses on the (1) functional
requirements for detecting specific microorganisms and the genes
that they harbor and express;(2) examples of research activities
that take advantage of molecular detection technologies;(3) some of
the challenges faced when projecting development and use of novel
instruments that will utilize molecular techniques onboard
autonomous platforms;and future directions. Bringing these
advancements on autonomous platforms, monitoring required sample
collection and processing schemes will differ from those currently
used (i.e. biomedical diagnostics). This book is the first of its
kind to compile current technologies for studying organisms in
situ. It will aid in transfer technology to oceanographers,
ecologists, microbiologists, and environmental scientists with
needs for a remote, in-water sensing capability and for integration
with larger scale observatory operations. With this network in
place, there is a potential to bridge the gap among regulatory
agencies and academics about how this kind of technology can be
used for research and monitoring purposes.
Arising out of the Third International Symposium held in New
Jersey, this book represents the state-of-the-art in ocean
management. An international group of contributors cover such
topics as: regional seas and embayments; new concepts in the
governance of ocean space assessment standards and issues; ocean
resources and sustainable development; ocean space development; and
related technologies. From the Baltic to the Caribbean, from the
Adriatic to the Atlantic, the problems of ocean management are
fully discussed, and proposals made to meet the challenges of the
next decade. This book should be of interest and use to anyone
working in coastal and ocean management.
Four years have elapsed since the preparation of the original
Russian version of this book. This is a long time when dealing with
such actively expanding fields of oceanography as research into
small-scale structures and the investigation of hydro physical
processes. Over this period new quick-response devices have been
developed and successfully used for measurements taken in various
ocean areas. Improvements in high-frequency meters used to measure
hydrophysical parameters has enabled workers to obtain more
accurate absolute values of the fluctuations measured by such
devices. In view of this scientific progress, some of the ideas
presented in this book now require additional explanation. Great
care should be used in dealing with the absolute fluctuation values
of hydro physical fields, since the methods used for the
determination of the accuracy of the high-frequency measuring
devices have been imperfect in the past. Never theless, it would
appear that the results of the investigations summarized in this
book have not lost their importance, and that the established laws
governing small-scale pro cesses in the ocean are of a sufficiently
universal nature and, as such, have not been shattered with the
qualitative and quantitative advances in devices used for
measurements taken in oceans. The authors feel that their work is
of interest to English-speaking readers. The appearance of the
English translation of the book is, to a very large extent, due to
the tremendous amount of editing work brilliantly done by Prof. H.
Tennekes."
This book focuses, in seven chapters, on the perspectives and
solutions that different research groups offer to try to address
problems related to SDG 14: Life Below Water. The different
objectives developed in SDG 14 are treated independently, with an
attempt to give a global vision of the issues. The mechanism used
to select the book's content was through an Artificial Intelligence
program, choosing articles related to the topics by means of
keywords. The program selected those articles, and those that were
not related to the topic or did not focus on SDG 14 were discarded
by a subject matter expert. Obviously, the selection was partial
and the entire subject is not covered, but the final product gives
a very solid idea of how to orient ourselves to delve deeper into
the topic of SDG 14 using published chapters and articles. The AI
program itself selected the text of these contributions to show the
progress in different topics related to SDG 14. This mode of
operation will allow specialists (and non-specialists) to collect
useful information for their specific research purposes in a short
period of time. At a time when information is essential in order to
move quickly by providing concrete answers to complex problems,
this type of approach will become essential for researchers,
especially for a subject as vast as SDG 14.
This book contains articles by oceanographic researchers from the
(former) USSR and presents new data on various aspects of the Black
Sea. The topics include Black Sea thermohaline, hydrochemical and
optical structures, the dynamics of the Main Black Sea current and
deep layers, wave phenomena in shelf areas and modelling of complex
marine systems. Aslo included are some experimentally derived
results which allow a deeper insight into the problem of O2 and H2S
coexistence in the Black Sea. The commonplace notions about the
structure of the oxic/anoxic interface are critically evaluated.
The last two decades have seen unprecedented developments in marine
science and technology. Large scale, international long-term
scientific programmes have emerged for monitoring the state of the
ocean environment and the rapid development of the offshore oil
industry has provided the technological means for a range of other
maritime developments. The purpose of this book is to review key
developments in this field. Three major themes are developed
throughout the book: the key importance of technical developments
in ocean management; the application of these developments to
specific sea uses ranging from fish farming to the deep sea
disposal of industrial waste; and the long term general issues
raised - and to some extent solved - by science and technology.
This book should be of interest to students and professionals
involved in maritime studies, oceanography, offshore engineering
and environmental science.
