OS19 "Biophysical factors affecting the growth and survival
of aquatic organisms"
The interaction of physical flow mechanisms with biological processes is fundamental for life in aquatic systems. Fluid flow plays a role in a wide range of biological processes by (i) controlling transport rates of material such as nutrients, (ii) imparting forces and (iii) affecting biological interactions. This session seeks to promote work that incorporates fluid mechanics into an understanding of the growth and survival of aquatic organisms at scales comparable to the biological entity and/or the dominant physical process. Contributions are encouraged from research involving marine and freshwater systems including, but not limited to, the following topics: macrophyte-flow interaction, coral-flow interactions, low-Reynolds number feeding/interception behaviour, turbulence/phytoplankton interaction, and mass transfer/ecological interactions in the benthos. All methodology, especially, multi-approach studies are welcome.

OS02 Coupled Biophysical Processes, Fisheries Resources, and Climate Variability in Coastal Ecosystems of the Northeast Pacific Ocean
The past decade has shown renewed scientific investigations in coastal regions of the Northeast Pacific (NEP). New interdisciplinary programs have foci ranging from phytoplankton and harmful algal blooms (ORHAB), recruitment of benthic invertebrate larvae (PISCO), wind-driven cross-shelf exchange (CoOP) and the mechanisms that regulate the success of holozooplankton and fish (GLOBEC). These programs supplement established longer-term observation programs (CalCOFI, MBARI, Line P, Vancouver Island Shelf) and examine the responses of coastal ecosystems to forcing over broad spatial and temporal scales. A common goal of these programs is to elucidate the biological-physical mechanisms responsible for correlative changes that have been observed in the NEP. This session will provide a forum for investigators from a number of disciplines -- climatologists, physicists, plankton biologists, and fisheries scientists to present recent findings from the NEP region. We encourage presentations that link observations over multiple disciplines or datasets.

OS27 Physics and Biology of Antarctic Continental Shelf Waters
During the past decade several research programs have focused on the physical and biological oceanography of Antarctic continental shelf waters. Results from these show that 1) the Antarctic shelf region provides a habitat that supports a diverse and productive biological food web and 2)the hydrography and circulation of the Antarctic shelf regions is complex and is linked to variability in the Antarctic Circumpolar Current. Recent interest has focused on identifying and understanding the physical and biological processes of the Antarctic continental shelf waters that are ongoing in the austral winter. Of particular interest are those processes that determine sea ice concentration and extent, winter primary and secondary production, and winter distribution and foraging ecology of top predator populations. This special session is designed to provide aforum for the exchange of information resulting from these recent programs. Papers that consider 1) linkages between regional physical and biological phenomena, 2) overwintering strategies of plankton and top predator populations, 3) observations of physical processes which influence the physical and biological environments (e.g., cross-frontal exchanges, turbulent mixing), 4) sea ice physics, and 5) sea ice production are especially encouraged.

OS42 Nutrient Dynamics in Coastal Ecosystems: Linking Physical and Biological Processes
Understanding the relative importance of natural and human-induced elevated-nutrient events on coastal ecosystems is an important global issue. As yet there are few clear answers. Considerable progress has been made in our understanding of the hydrology of coastal waters, the ecology of the organisms living in these waters and their physiology; and nutrient dynamics have been an important component in many of these studies. Yet, of these studies, few cross the traditional lines of discipline. In temperate regions, upwelling and large scale physical processes have long been shown to deliver substantial levels of nutrients to coastal ecosytems, thereby supporting high biomass communities such as kelp forests. In contrast, tropical marine communities are generally considered to be nutrient limited where they exist on tightly recycled and newly generated nutrients. However, recent research has shown that not all tropical areas conform to this paradigm. The effects of localized and large scale physical processes on tropical benthic or pelagic communities remains largely unstudied. Anthropogenic nutrient imputs in both temperate and tropical regions have often been suggested as the primary cause of large scale phase shifts in benthic marine communities. The precise role of nutrients in these ecosystem-wide changes remains largely debated. This session is intended to be a forum where researchers from a variety of disciplines present their views of how best we can understand the real influence of elevated nutrients on coastal ecosystems. An integral part of the session is to open the floor for discussion in the form of open questions for any of the speakers in the session. We hope to break down some of the barriers between researchers traditionally working in separate fields.
