IUTAM Symposium on Advances in Mathematical Modelling of Atmosphere and Ocean Dynamics


Book Description

The goals ofthe Symposium were to highlight advances in modelling ofatmosphere and ocean dynamics, to provide a forum where atmosphere and ocean scientists could present their latest research results and learn ofprogress and promising ideas in these allied disciplines; to facilitate interaction between theory and applications in atmosphere/ocean dynamics. These goals were seen to be especially important in view ofcurrent efforts to model climate requiring models which include interaction between atmosphere, ocean and land influences. Participants were delighted with the diversity ofthe scientific programme; the opportunity to meet fellow scientists from the other discipline (either atmosphere or ocean) with whom they do not normally interact through their own discipline; the opportunity to meet scientists from many countries other than their own; the opportunity to hear significant presentations (50 minutes) from the keynote speakers on a range ofrelevant topics. Certainly the goal ofcreating a forum for exchange between atmosphere and ocean scientists who need to input to create realistic models for climate prediction was achieved by the Symposium and this goal will hopefully be further advanced by the publication ofthese Proceedings.




A Coastal Air-Ocean Coupled System for the East Asian Marginal Seas


Book Description

A Coastal air-ocean coupled system (CAOCS) that includes the Princeton Ocean Model (POM) as the ocean component and the Pennsylvania State University/National center for Atmospheric Research (PSU/NCAR) Mesoscale Model Fifth Generation (MM5) as the atmospheric component was developed for the east Asian marginal seas (EAMS) - a littoral environment that is a common operating area for the United States Navy (USN). CAOCS output verified against surface wind data from the National Centers for Environmental Prediction (NCEP) and sea surface temperature (SST)/Sea Surface Salinity (SSS) data collected from buoy stations. CAOCS output clearly shows the significance of atmospheric and oceanic Mesoscale features and their associated air-sea interaction processes such as coastal upwelling Ekman transport and enhancement of upward vertical motion during cyclogenesis. These Mesoscale features and air-sea interaction processes occur during periods prior to summer monsoon onset as well as during time periods following summer monsoon onset. The study provides support that CAOCS does perform well in forecasting EAMS surface current circulation SST/SSS structure surface wind stress and low-level atmospheric structure. Sone weaknesses of CAOCS were identified that will aid in future improvement of the model.




Impacts of climate change on fisheries and aquaculture


Book Description

This report indicates that climate change will significantly affect the availability and trade of fish products, especially for those countries most dependent on the sector, and calls for effective adaptation and mitigation actions encompassing food production.




The First Global Integrated Marine Assessment


Book Description

The World Ocean Assessment - or, to give its full title, The First Global Integrated Marine Assessment - is the outcome of the first cycle of the United Nations' Regular Process for Global Reporting and Assessment of the State of the Marine Environment, including Socioeconomic Aspects. The Assessment provides vital, scientifically-grounded bases for the consideration of ocean issues, including climate change, by governments, intergovernmental agencies, non-governmental agencies and all other stakeholders and policymakers involved in ocean affairs. Together with future assessments and related initiatives, it will support the implementation of the recently adopted 2030 Agenda for Sustainable Development, particularly its ocean-related goals. Moreover, it will also form an important reference text for marine science courses.




Intakes and Outfalls for Seawater Reverse-Osmosis Desalination Facilities


Book Description

The book assembles the latest research on new design techniques in water supplies using desalinated seawater. The authors examine the diverse issues related to the intakes and outfalls of these facilities. They clarify how and why these key components of the facilities impact the cost of operation and subsequently the cost of water supplied to the consumers. The book consists of contributed articles from a number of experts in the field who presented their findings at the "Desalination Intakes and Outfalls" workshop held at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia in October, 2013. The book integrates coverage relevant to a wide variety of researchers and professionals in the general fields of environmental engineering and sustainable development.




Global Seagrass Research Methods


Book Description

This thorough and informative volume presents a set of detailed, globally applicable techniques for seagrass research.The book provides methods for all aspects of seagrass science from basic plant collection to statistical approaches and investigations of plant-animal interaction. The emphasis is on methods that are applicable in both developing and developed countries. The importance of seagrasses in coastal and near shore environments, and ultimately their contribution to the productivity of the world's oceans, has become increasingly recognised over the last 40 years.Seagrasses provide food for sea turtles, nearly 100 fish species, waterfowl and for the marine mammals the manatee and dugong. Seagrasses also support complex food webs by virtue of their physical structure and primary production and are well known for their role as breeding grounds and nurseries for important crustacean, finfish and shell fish populations. Seagrasses are the basis of an important detrital food chain. The plants filter nutrients and contaminants from the water, stabilise sediments and act as dampeners to wave action. Seagrasses rank with coral reefs and mangroves as some of the world's most productive coastal habitat and strong linkages among these habitats make the loss of seagrasses a contributing factor in the degradation of the world's oceans.Contributors from around the world provide up-to-date methods for comparable collection of ecological information from both temperate and tropical seagrass ecosystems.




Reefs at Risk Revisited


Book Description




World Atlas of Seagrasses


Book Description

Seagrasses are a vital and widespread but often overlooked coastal marine habitat. This volume provides a global survey of their distribution and conservation status.




Expanding Mariculture Farther Offshore


Book Description

It is also recommended that efforts be increased to farm lower trophic levels species and optimize feeds and feeding in order to minimize ecosystems impacts and ensure long-term sustainability. Similarly, risk assessments and/or environmental impact assessment and monitoring must always be in place before establishing offshore farms, and permanent environmental monitoring must be ensured. All coastal nations should be prepared to engage actively in developing the technological, legal and financial frameworks needed to support the future development of offshore mariculture to meet global food needs. The workshop report highlights the major opportunities and challenges for a sustainable mariculture industry to grow and further expand off the coast.




The State of Food Security and Nutrition in the World 2018


Book Description

New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.
