SYMPOSIUM J05 DATA ASSIMILATION IN METEORLOGY AND OCEANOGRAPHY

Program schedule of papers for SYMPOSIUM J05:

Data assimilation research started in dynamic meteorology five decades ago to use observations systematically in order to improve the forecast skill of operational weather prediction models. Thus the field has been quite mature in large-scale dynamic meteorology for a number of years.The delayed development of data assimilation in oceanography was due first to the lack of a unifying focus such as weather prediction;second, to the lack of adequate datasets, with speca/time coverage comparable to the meteorological one.The observational revolution of the 90's in global scale oceanography and the successes of satellite altimetry and scatterometry have spurred the beginning and rapid growth of oceanographic data assimilation in the last decade.The synposium will emphasize four major objectives for data assimilaiton applications, in both meteorology and oceanography :

SYMPOSIUM J21 SOURCES AND SINKS OF ENVIRONMENTALLY IMPORTANT SUBSTANCES (excluding CO2)

Program schedule of papers for SYMPOSIUM J21:

International efforts at curbing the emission of ozone-depleting gases have met with initial success, as emissions have been reduced significantly and total atmospheric chlorine has begun to decline. However, there still are issues remaining with some of the CFC replacement compounds, as well as some compounds of natural or mixed origin. Although the new CFC replacements offer substantial relief for stratospheric ozone depletion, they still can contribute significantly to global warming. Radiative forcing by these gases, per molecule, is similar to that for the CFCs, many of them have atmospheric lifetimes of 10-50 years, and none of them offers the global cooling effects associated with CFC-induced ozone depletion. Consequently, these gases can have higher estimated global warming potentials than the gases they are replacing.

There are many naturally occurring substances which, albeit to a lesser extent, can influence ozone depletion and greenhouse warming. The shorter-lived of these compounds also play a significant role in the chemistry of the marine boundary layer and troposphere. Results show the ocean to be a contributor of both volatile halocarbons and sulphur containing compounds to the atmosphere, but the specific sources and sinks within the ocean are poorly understood. The role of the ocean as a net source or sink of methyl bromide, for example, depends upon a fine balance between production and degradation in the ocean. Because marine data are sparse and inconclusive and atmospheric budgets often appear out of balance, the ocean's contribution to the atmospheric burden of these gases is often unresolved. Terrestrial sources have been invoked for a number of natural halogens, but systematic studies of these have been few.

The aim of this session is to bring together atmospheric, marine and biological scientists to look at the sources and sinks of a wide range of substances that have a potentially significant influence on climate. Papers dealing with all substances (with the exception of CO2) will be considered with particular focus on the CFC replacements and naturally produced compounds which hitherto have received little attention or for which results are still inconclusive.

SYMPOSIUM J23 GEOPHYSICAL HAZARDS: RISK ASSESSEMENT, MITIGATION AND WARNING SYSTEMS

A symposium in honour of Dr. Mohammed El-Sabh.

Program schedule of papers for SYMPOSIUM J23:

Geophysical hazards, such as earthquakes, volcanic eruptions, landslides, floods, droughts,tsunamis,storm surges, wildfire, tropical cyclones and extreme weather events constitute major problem in many developing and developed countries. With the growth in world population, the increasing pressure on natural resources in newly developing areas, and the increasing cost and sophistication of engineering structures and technical installations, there is an urgent need to seek to understand the potential threats posed by natural hazards and to ascertain increasing preparedness and appropriate ways of mitigating the damaging effects.

Much has been accomplished since the onset of the UN International Decade for Natural Disaster Reduction(IDNDR). The aim of this Inter-Associations Symposium is to stimulate synergistic interactions between all geophysicists on common interests in the field of natural hazards, especially across disciplinary boundries. The scope seeks through contributed prsentations to recognize the technical and scientific progress made during the last ten years in research related to any aspects of geophysical hazards to accomplishing the goals set forth for the Decade, including risk assessment; the application of known preparedness and mitigation approaches; and the development and use of scientific and engineering knowledge to improve warning systems, the disaster preparedness and mitigation in practise.

SYMPOSIUM J25 OCEAN/ATMOSPHERE VARIABILITY AND PREDICTABILITY

Program schedule of papers for SYMPOSIUM J25:

The symposium will be divided into three parts:

J25-A. The largest interannual variability is associated with the tropical Pacific El Nino/Southern Oscillation (ENSO) cycle. Efforts to understand and predict this phenomenon are an important component of current climate research. Papers are invited on the analysis and prediction of ENSO events and their associated widespread regional impacts.

J25-B. The sucessful forecasting of climate from seasons to years in advance remains a major scientific challenge. The climate system varies substantially on intradecadal time scales, such as annually and quasi-biennially, and much of this variability is still poorly understood. Evidence suggests that coupled ocean-atmosphere interactions may play some role in such variability, and may lead to possible predictability. Papers are welcome on any aspects of coupled variability and predictability on time scales from seasons to decades (CLIVAR-GOALS), and in particular, on coupled behaviour in monsoon variability, tropical and extratropical quasi-biennial signals, and mid-latitude modes such as the Pacific North American pattern and the North Atlantic Oscillation. Papers which address aspects of variability of ocean and/or atmosphere circulation on seasonal and longer time scales are also welcome.

J25-C. The focus of this symposium will be on decadal to centennial variability and sensitivity. Recent studies have revealed a number of atmospheric and oceanic signals on the timescale from ten to hundred years, with possibilities for significant interactions between the atmosphere and ocean. Data and model examples of longer term variability have been seen especially in the Atlantic and Southern Ocean sectors, especially associated with the thermohaline circulation. Pacific modes include variability in the mid-latitudes associated with the gyre-circulation and possible interactions with long-term ENSO variability. Papers are welcomed on data analysis and numerical simulation of global or regional variability in the oceans, atmosphere, ice and other parts of the climate system.

SYMPOSIUM J39 ROTATING AND STRATIFIED FLUIDS

Program schedule of papers for SYMPOSIUM J39:

This session will focus on an assessment of our current fundamental understanding of the dynamics of rotating and/or stratified fluids and of the application of this knowledge to the prediction of aspects of the dynamics of the atmosphere and oceans. While the principal focus will be on systems for which rotation and stratification are both important, contributions will also be welcomed on studies which focus solely on either rotation or stratification effects. We encourage the submittal of any theoretical, numerical, laboratory or field experimental contribution related to rotating and/or stratified fluids that has potential application to the solution of problems related to atmospheric and oceanic phenomena. Topical areas of interest include, but are not limited to,

Contributions dealing with the application of fundamental knowledge of rotating and/or stratified flows to areas such as: (i) the parameterization of sub-grid scales of Atmosphere and Ocean General Circulation Models (GCMs), (ii) the prediction of fluid structure interactions, and (iii) the development of hydraulic models, are also welcome.

SYMPOSIUM J49 SMALL-SCALE FLOW, TURBULENCE AND MIXING

Program schedule of papers for SYMPOSIUM J49:

This symposium will focus on the nature and effects of turbulence in the ocean and the atmosphere, where the turbulent eddies have scales of hundreds of metres and smaller, and on flows that are directly affected by such turbulence. Turbulence in the ocean can be loosely divided into two forms: that which occurs throughout the oceans via breaking internal waves and similar processes in the mixed layer, thermocline and deep ocean, and that which occurs in particular locations such as sea straits and near seamounts. In the atmosphere, a similar division can be made between "ubiquitous turbulence", and turbulence that is specific to particular phenomena and regions. The symposium will cover all flows where these forms of turbulence are important. Papers that describe the onset of turbulence, its physical properties and the factors that control it, and its effects on the larger scale environment such as mixing and transport, are sought, as well as flows that are influenced by such turbulence.

III. Separate IAPSO Symposia

SYMPOSIUM P07 STABLE ISOTOPES AND TRACE SUBSTANCES: THEIR USE IN OCEANOGRAPHY AND CLIMATE RESEARCH ON VARIOUS TIMESCALES.

Program schedule of papers for SYMPOSIUM P07:

During the past decades, stable isotopes and trace substances (e.g., radioactive isotopes and elemental ratios) have found widespread application in modern and paleoceanographic circulation studies, as well as in marine paleoclimate research. The result has been a vast improvement in our understanding of modern circulation, as well as climate and the manner in which these proxies records ocean and climate history. The purpose of this symposium is to present and discuss recent advances in the development and use of these diverse methods to address the following scientific topics:

We encourage both traditional stable isotope contributions as well as studies which combine stable isotopes with other tracers, such as, for example, radioactive isotopes or elemental ratios to gain insight into the topics listed above in novel ways. The symposium will address both observational and model studies.

SYMPOSIUM P08 BIOGEOCHEMICAL CONSTRAINTS IN THE OCEAN - CONTROLS, MODELLING AND PREDICTION

Program schedule of papers for SYMPOSIUM P08:

The past decade has witnessed remarkable advances in our understanding of role of biogeochemical processes in the global scale marine environment, and in the factors which regulate them. These advances have resulted from key, critical experiments and observational programs (e.g., IRONEX, JGOFS, TRE and WOCE) which are continuing to bear intellectual fruit as analysis and synthesis proceeds. While many remarkable insights have been gained, there are still many unanswered questions. We would like to encourage contributions which both build on these newly established paradigms, and reveal the remaining major issues that need to be addressed. Some (but not all) of the issues include:

We invite both observationalists and modellers to contribute.

SYMPOSIUM P09 ESTUARINE PROCESSES (JOINT IAPSO/IABO)

Program schedule of papers for SYMPOSIUM P09:

Estuaries are one of the most complex coastal environments comprising large varieties of geomorphological, biogeochemical, physical and biological processes. Furthermore, estuaries are very sensitive to even minimum variabilities as well as those expected by the impact of any climatic change. It is now becoming evident that these environments cannot be studied from one or two single disciplines alone any longer, but by teams of multi and interdisciplinary researchers working within a wide range of space and temporal timescales. Therefore, the objective of the proposed interdisciplinary symposium is to provide a forum for discussion of the relevant estuarine process in general and also particular study cases.

SYMPOSIUM P11 CLOSED, SEMI-ENCLOSED AND MARGINAL SEAS: PHYSICAL, CHEMICAL AND BIOLOGICAL PROPERTIES (JOINT IAPSO/IABO)

Program schedule of papers for SYMPOSIUM P11:

The importance of closed, semi-enclosed and marginal seas has been extensively recognized in recent years not only because of their importance to the surrounding riparian countries but also as laboratory basins for the study of processes of global importance. Marginal seas are characterized by thermohaline circulations,deep water formation convective cells, complex local ecosystems ranging from strongly euthrophic to oligothrophic, which, among many others, are crucially important on the global scale and for climate issues.The symposium will be fully interdisciplinary with presentations related to the physical, chemical and biological properties of the basins and their interactions. Observational and modeling aspects will both be covered.

SYMPOSIUM P12 GLOBAL WATER MASS ANALYSIS

Significant advances in information technology and numerical modelling and outstanding efforts of the oceanographic community to increase the density of oceanographic observations in all regions of the world ocean have made global water mass analysis a reality. The symposium will discuss all aspects of the life history of water masses from formation through spreading and mixing to decay. It will focuss on quantitative assessments of the role of water masses in climate variability and climate. It will present new developments in techniquesand observations for the determination of water mass formation rates and age and bring together researchers from all relevant disciplines, including regional oceanographers, tracer oceanographers and ocean modellers.

SYMPOSIUM P14 HYDRAULIC CONTROL AND ENTRAINMENT IN STRAITS, SILL FLOWS, AND DENSITY CURRENTS

Flows through constrictions and over sills are often hydraulically controlled and mix intensely. Often the flows are at least partially driven by density differences across the obstruction, and most of the transport is carried by density currents. In many cases these flows are the primary exhange between open waters and marginal seas and estuaries. Consequently, much work is being done with observations, numerical modeling, and laboratory experiments to understand and predict the control conditions and entrainment rates. This Symposium is planned to assess the state of these diverse efforts.

The Symposium will occupy one day. The morning session will be devoted to invited reviews and a few contributed talks. The afternoon will be a poster session with brief oral presenations. At the end, a raporteur will summarize and suggest future directions.

SYMPOSIUM P16 RECENT IMPROVEMENTS TO DEEP-SEA RESEARCH THROUGH USE OF SUBMERSIBLES, ACOUSTIC TOMOGRAPHY AND IN-SITU LONG TERM OBSERVATIONS

This Symposium will focus on recent progress in understanding phenomena occurring in the deep oceansthrough use of manned research submersibles, remotely operated vehicles (ROV and AUV), acoustic tomography and in-situ long-term observatories. For example, venting of both hydrothermal and cold fluids from the deep ocean floor has provided a new picture of the mass and heat fluxes between the ocean and crust with possible implications for oceanography. In-situ observations by underwater cables are emerging to be important tools for monitoring time-variations of oceanic processes (whether periodic or sporadic). Acoustic tomography is capable of yielding 3-D snapshots of oceanographic conditions. We aim to synthesize the present status of research and to establish a new vision of oceanography in the next century.

The aim of this one-day workshop is to bring together the international scientific community to exchange knowledge about the oceanographic processes in the coastal seas around developing countries. It will focus on the consequences of natural oceanographic processes and intense human activities on the physics, chemistry and biology and to identify the most important priorities for future research. Contributions are invited on a number of related themes with particular emphasis on recent studies on the oceanographic processes in these coastal seas; forces affecting the spatial and temporal distributions of the physical, chemical and biological properties in these seas; and identification of gaps in our knowledge to define priorities for future research. Preference will be given to interdisciplinary and multidisciplinary contributions.
