Coastal and Estuarine Research Federation 20th Biennial ConferenceEstuaries and Coasts in a Changing World1-5 November 2009, Portland, Oregon, USA

Topic: Physical

SCI-213: Physical Modeling of Coastal Systems (Poster Only)

SCI-018: Estuarine Sedimentary Processes and Products.

Conveners: Timothy Dellapenna (dellapet@tamug.edu) and Carl Friedrichs (cfried@vims.edu)

Estuaries tend to be some of the most dynamic marine sedimentary systems. The effects and products of these processes are manifest in a wide variety of manners. This session will broadly focus on the link between sedimentary process and product, with special emphasis on mechanism of sediment deposition, erosion, sediment mixing and record of processes in modern strata; and the link between sedimentary processes and benthic habitats.

SCI-021: Exploring the Linkages between Nearshore Oceanography and Onshore Benthic Environments.

Conveners: Sarah Dudas (Sarah.Dudas@science.oregonstate.edu) and Brock Woodson (cwoodson@hawaii.edu)

Investigating the linkages between nearshore oceanography and onshore benthic communities is crucial for understanding ecological patterns, and the impact of larger scale influences (i.e., climate change) on marine ecosystems. These linkages include but are not limited to: larval dispersal, population replenishment (i.e., settlement and recruitment to adult populations), and population connectivity; and span several disciplines such as oceanography, ecology, genetics, physiology and biogeography. The goal of this session is to bring together scientists working in all of these fields, in a variety of habitats (e.g., estuaries, open coast), to share the latest advancements in establishing these linkages and generate new ideas and collaborations.

SCI-070: Hydrologic Prediction in Estuaries and Coastal Ecosystems.

Conveners: William Nuttle (chant@marine.rutgers.edu) and Jaye Cable (jcable@lsu.edu)

Hydrology defines estuaries. Many changes that occur in estuarine and coastal systems are related to, and can be predicted from, variation and change in their hydrologic regime. These include change and variation in water quality, fisheries, wetland habitat and other ecological characteristics. This session will explore the mechanisms by which variable hydrologic processes drive change in estuarine and coastal ecosystems. Also, we invite presentations that illustrate how hydrologic information can be used to predict the response of estuarine and coastal ecosystems to a changing world.

SCI-031: Parameterizing Estuarine Variability.

Conveners: Rocky Geyer (rgeyer@whoi.edu), Parker  MacCready (parker@ocean.washington.edu), Dave Ralston (dralston@whoi.edu) and Jim Lerczak (jlerczak@coas.oregonstate.edu)

In this session we are seeking the parameters that quantify the variations in physical processes in estuaries. This variability may be the temporal and/or spatial variability within one estuary - for example the spring-neap changes in stratification. We would also like the participants to consider the variability between estuaries, as in defining the parameters that allow us to distinguish between different types of estuarine regimes. Finally and most relevant to the theme of the conference, we would like to hear how these parameterizations will allow us to predict the response of estuarine systems to changes in forcing conditions associated with regional or global climate change. The emphasis of this session is on physical processes, but we encourage the participants to link the physical variables to ecology, sediment transport, water quality and other interdisciplinary issues.

SCI-056: Physical, Biological and Chemical Interactions of Estuaries, Bays and Shelves.

Conveners: Chunyan Li (cli@lsu.edu), Rubao Ji (rji@whoi.edu), Changsheng Chen (c1chen@umassd.edu) and Nancy Rabalais (nrabalais@lumcon.edu)

The environmental interactions of coastal bays and continental shelves are subjects involving multiple disciplines with wide ranges of temporal and spatial scales. Estuaries and shelves are integrated systems and a holistic view will help better describe many of the interdisciplinary and multidisciplinary processes. This session will cover interdisciplinary and multidisciplinary studies involving the newest observations and numerical modeling, on normal and extreme weather related dynamics of exchange and interactions among estuarine, nearshore and offshore waters and waterborne materials, as well as the biological and environmental responses and implication to and resilience of the ecosystems.

SCI-090: Poorly Understood Physical Processes in Estuaries and Coasts.

Conveners: Alejandro Souza (ajso@pol.ac.uk) and Arnoldo Valle-Levinson (arnoldo@ufl.edu)

There are still processes in estuaries and coastal areas that are not well understood and therefore missing from the models. This is because the models need to properly include mechanisms such as internal and inertial waves, Langmuir circulations and boils. Other effects not normally included in estuarine models and that are not well understood are: the influence of ground water, the convective mixing due to tidal straining and or advection, the effects of tidal pumping under different tidal asymmetries and the rectification of tides. We seek presentations that deal with these poorly understood mechanisms.

SCI-049: Significance of River-Ocean Coherence for Fluxes and Fate of Terrestrial Material.

Conveners: Tara Kniskern (tknisker@ucsc.edu), Miguel Goni (mgoni@coas.oregonstate.edu), Rob Wheatcroft (raw@coas.oregonstate.edu) and Katie Farnsworth (katie.farnsworth@iup.edu)

Approximately 1.8 gigatons of suspended material (e.g., sediment, particulate organic carbon) are delivered annually by rivers to the coastal ocean. The dispersal, transformation and accumulation of these constituents are strongly modulated by temporal variability in discharge and the wave and current conditions during and just after flood. Over time scales of seasons to millennia, variability in river-ocean coherence potentially influences depositional patterns, the formation of cm-scale stratigraphy and geochemical cycling. We invite theoretical and observational studies that investigate patterns of river-ocean coherence/non-coherence and the resultant impact on sediment delivery, dispersal, accumulation, geochemical cycling and physical-biological interactions.

SCI-040: The Response of Deltas and Coastal Wetlands to Global Change.

Conveners: Carles Ibáñez (carles.ibanez@irta.cat) and John Day (johnwday@bellsouth.net)

Deltas and other low-lying coasts are rich in wetlands with great ecological and socioeconomic value. These coastal systems are endangered by global change drivers such as climate change, sea level rise, nutrient enrichment, infrastructure development and energy scarcity. A system approach including long-term socioecological research and modeling is requested in order to advance in the understanding and problem solving for a sustainable management of coastal areas. This session will address the recent concepts, methods and models for better understanding and management of the impacts of global change on deltas and coastal wetlands.

SCI-038: The Skagit Delta: Integrating Estuarine Geomorphology, Hydrodynamics and Ecology.

Conveners: Gregory Hood (ghood@skagitcoop.org) and John Rybczyk (John.Rybczyk@wwu.edu)

The Skagit is the largest river draining into Puget Sound, accounting for 34% of the Sound's freshwater inflows and over 40% of the Sound's threatened wild Chinook salmon. The river's regional importance to Chinook salmon motivates both research and restoration efforts in the basin. The Skagit is an ideal natural laboratory for addressing interacting issues in an estuarine system, including endangered species recovery, exotic species control, habitat restoration, urban sprawl, climate change, flood management, and competing social priorities for land use. To facilitate interdisciplinary communication, this session brings together scientists investigating the ecology, geomorphology and hydrodynamics of the Skagit Delta.

SCI-104: Turbulence and Mixing in Estuaries and the Coastal Ocean.

Convener: Ed Zaron (zaron@cee.pdx.edu)

Vertical and horizontal turbulent transport of momentum, sediment, plankton, nutrients and pollutants are often of first-order significance for understanding property budgets in the coastal ocean and estuaries. Turbulence and mixing vary greatly in response to tidal, riverine and atmospheric forcing, and between regimes dominated by boundary forcing and regimes dominated by internal, shear-driven, processes. Understanding and modeling turbulent processes across these regimes is a foundation for prediction and management of estuarine and coastal processes. This session provides a forum for the presentation of recent advances in turbulence observations, process studies, and models of relevance to coastal and estuarine environments. Results from studies that address multiple interacting scales are encouraged, particularly as they advance the state of the art of applied turbulence modeling for regional hydrodynamic modeling.
