(A) The physical chemistry of water and its influence on physico-chemical on oceanographic processes
It is only within about the last decade that physical chemists have begun to understand the structure of liquid water. The fundamental properties of water affect all processes in the oceans, from hydration of ions to surface tension, diffusion and sound transmission, gas solubility, etc. A session of the fundamentals of the properties of water would assist both physicists and chemists in understanding aqueous processes.
(B) Chemical tracers in ocean dynamics
Tracers used since oceanography evolved have been chemical, e.g., salinity, dissolved oxygen, nutrients, isotopes, radiochemicals and, recently, anthropogenic compounds such as halogenated carbon compounds and substances such as sulfur hexafluoride. Highly halogenated compounds are believed to be "inert" and subject only to conservative processes. However, halogenated compounds may be photochemically active in the boundary layer and below. Micro-organisms may metabolise these compounds. They probably adsorb particles. What corrections need to be applied for this "non-conservative" behavior when a heterogeneous distribution of particles is present, as is usually the case in the ocean? Micro-organisms are known, for example, to convert "inert" hydrocarbons into acetic acid.

A joint symposium with IAMAS
Both the physics and the chemistry of the air/sea interface are poorly understood, yet these processes exert the control on fluxes of energy and matter between air and water. Chemists have a weak understanding of boundary layer physics, while physicists need to be aware of the powerful influence of chemical processes on gas exchange (e.g., carbonic anhydrase in the microlayer vastly accelerates CO2 exchange across the air/sea interface); evaporation (molecules of water, etc., must diffuse or otherwise pass through the organic film of the microlayer); protolytec reactions driven by solar radiation flux which produce highly reactive chemical species, and so on.

A joint IAPSO/IAG/IAMAS symposium
Within the solid Earth-Atmosphere-Ocean system, total angular momentum is approximately conserved. This implies that highly accurate space geodetic measurements of changes in solid earth rotation rate and in position of the rotation rate and in the position of the rotation axis will measure fluctuations in the angular momentum of the oceans and atmosphere. For example, motion of the rotation axis represents global scale, circulation and redistribution of water and air mass over time scales from days to years, which is accurate at the 1-2 millimetre level. This symposium will examine causes of earth rotation variations in the atmosphere and hydrosphere, and the constraints that observations of those variations place on our understanding of the fluid parts of the earth.

There will be a focus on the interdisciplinary aspects of closed, semi-enclosed seas, and marginal seas. Marginal seas may be defined as seas partially enclosed by the continents' margin, i.e., enclosed at least on three sides or with restricted inflow/outflow regions. Examples would be the Yellow Sea (surrounded by continental margins on three sides), and the Japan Sea, limited by mainland China and Japan. In the Australian region, a sea satisfying these definitions would be the Coral Sea.

This symposium has a special interest in tropical and southern hemisphere estuaries. Although there are a large number of estuaries in the southern hemisphere, only a handful of them have some studies made on their physical processes. Most of these estuaries are located in tropical to temperate regions where the interplay among the atmosphere, the water (ocean and continental) and the land produce large variations in the basic parameters. As a consequence, many modifications take place at different time and space scales that produce large stress over the biota, change the pattern of sediment and pollutant transport, modify the outflow of water into the inner shelf, and so on. Therefore, the objective of the proposed sympsium is to provide a forum for discussion of the relevant physical processes that take place in southern hemisphere estuaries as they are the basic element needed for specialists in other estuarine disciplines to pursue their own research.

This symposium focuses on the geophysics of sea ice and on the role of sea ice in oceanography, i.e. what makes an ice-covered sea different from an open sea. The vertical dimension covers the atmospheric boundary layer, ice itself, and the mixed layer in the ocean. The topics of this symposium are (i) role of sea ice in climate, (ii) sea ice morphology and rheology, (iii) sea ice growth and decay, (iv) leads and polynyas, (v) marginal ice zone processes, (vi) mechanisms of air-ice-sea interactions, (vii) role of sea ice in oceanography, and (viii) radiative transfer in the atmosphere-ice-ocean system.

A one day workshop in the weekend during the conference period.
The ocean is the flywheel of the climate machine. Its effect on the operation of this machine requires accurate estimates of turnover rates of all major water masses. As a result, the study of water masses is an important component of international programs such as WOCE and CLIVAR. Modern water mass analysis can make use of analytical and modelling methods that were not available to the oceanographers when water mass analysis was introduced as a tool of the oceanographer. Questions such as isopycnal vs. diapycnal mixing, mixing between and within water masses, and age determination in a mixture of water masses of different age can now all be tackled quantitatively.
The workshop aims to bring together physical oceanographers, tracer oceanographers and numerical modellers in a discussion of modern quantitative methods of water mass analysis and their use in climate research.
