Recent Meetings of Interest to ISAR Members
Annual Meeting of the Association of American Geographers, Washington, DC, 14-18 April 2010
During the annual meeting of the Association of the American Geographers two specialty group sessions with an aeolian research focus will be held:
Aeolian Processes and landforms
This session is organized by Jean Ellis (University of South Carolina) and Bailiang Li (Texas A&M University), and co-sponsored by the Coastal and Marine and the Geomorphology Speciality Groups.
Aeolian processes and landform studies are gaining significance in Earth system research. Investigations of aeolian processes and landforms spanning all temporal and spatial scales are invited in this series of oral presentations. We encourage innovative research discussing arid landforms, dune morphology and migration, and grain-scale sand transport. Recent advances comparing laboratory- and field-based data sets and modeling studies are encouraged. We also seek papers that relate multiple temporal and/or spatial scales. We hope the papers will show the diversity of methods employed to understand aeolian processes and landforms, including laboratory experiments, long- and short-term field deployments, modeling, and satellite observations.
Coastal Geomorphology and Management
This session is organized by Jean Ellis (University of South Carolina) and Chris Houser (Texas A&M University), and is co-sponsored by the Coastal and Marine and the Geomorphology Specialty Groups
The coastal zone is a dynamic environment where biophysical and anthropogenic processes interact, and often clash. Global climate change, and its associated impacts, contributes to additional and significant pressure on the coastal zone. The environmental impacts are exacerbated with the increasing population in these regions. To effectively respond to these changes, knowledge of the fundamental processes and the interaction between these processes and humans is required. This multiple oral paper series, therefore, seeks presentations exploring recent advances in coastal geomorphology and management. We invite presentations on all aspects of coastal geomorphology and management, including, but not limited to: surf zone processes and landforms; beach-dune interactions; lagoon, estuary, mud-flat, and marsh dynamics; modeling; remote sensing of coastal waters and terrestrial landscapes; and rocky coast evolution. We also encourage presentations that broadly relate coastal geomorphology to coastal management, and research benefiting environmental managers and planners.
If you are interested in participating, please let the organizers know. Abstracts are due 28 October 2009; the call for papers is found at: http://aag.org/annualmeetings/2010/papers.htm#sessions
All questions should be directed to Jean Ellis (jtellis@mailbox.sc.edu). After submitting your paper to AAG, please send your paper title and abstract to Jean and she and Chris Houser will ensure your paper’s place in these special sessions.

European Geosciences Union, General Assembly 2010, Vienna, Austria, 2-7 May 2010
The following sessions at the upcoming EGU might be of interest to scientists working in aeolian research:
AS4.7 Aeolian dust: initiator, player, and recorder of environmental change
Convener: Peter Knippertz; Co-Convener: Jan-Berend Stuut
The effects of aerosols on climate and weather are among the large uncertainties of current atmospheric research. Mineral dust is an important natural source of aerosol with significant implications on radiation, cloud microphysics, atmospheric chemistry and the carbon cycle via the fertilization of marine and terrestrial ecosystems. In addition deposition of dust in sediments and ice cores are important climate indicators. This session is open to contributions dealing with (1) measurements of all aspects of the dust cycle (emission, transport, deposition, size distribution, particle characteristics) with in situ and remote sensing techniques, (2) numerical simulations of dust on global and regional scales, (3) meteorological conditions for dust storms and dust transport, (4) interactions of dust with clouds and radiation, (5) influence of dust on atmospheric chemistry, (6) fertilization of ecosystems through dust depostion, (7) any study using dust as a climate indicator including investigations of Loess, ice cores, lake and ocean sediments and dunes.
HS3.3/GM10.1 Coasts and estuaries
Convener: Andreas Baas; Co-Conveners: Hubert H.G. Savenije , Andrea Rinaldo , Marco Toffolon
Coasts and estuaries are dynamic environments of multi-scale interactions between land and water that are of great human and economic interest. Estuaries form the support system for ecosystems that are among the richest and most productive on Earth. This open session invites presentations on all aspects at the interface between subaquaeous and subaerial systems, including: surf zone and wave shoaling, swash zone dynamics, beach morphology and sediments, berm development, back-beach environments, coastal dune systems, lagoons, estuaries, bays, barrier island systems, mud-flats and coastal marsh lands, deltas, rock-platforms, cliff erosion processes, and other coastal and estuarine landforms and processes. The session covers sedimentary and erosional systems, the full range of temporal and spatial scales, experimental results and theoretical models, and also considers the impacts of climate change and sea-level rise.
SSS18 Experimental methods on soil erosion research
Convener: Manuel Seeger; Co-Conveners: John Quinton, Nikolaus J. Kuhn, Johannes Ries
Soil erosion processes are the result of the interaction of rainfall, runoff, wind and human activities with soil properties. After some decades of investigations, there is still a lack of knowledge on the process interactions and intensities at different scales. On the other hand, the advances in knowledge on erosion have raised new questions, like selective erosion processes, and for this the selective transport of nutrients and other soil constituents. Experiments are supposed to deliver data to elucidate these processes. For this, different methods have been developed for monitoring or simulating soil erosion in the field or in the laboratory. They may not only give hints about detachment, transport and deposition of solids, but also on the hydrology of runoff generation and a detailed view on flow routing on the soils surface. Within this session, we want to gather the results of different methodologies for experimental soil erosion research and their interpretation towards the parametrisation of soil erosion models or the understanding of complex soil erosion processes at different scales. We invite contributions concerning: (1) The development of measurement techniques; (2) field and laboratory application of experimental methods experiments concerning water erosion, wind erosion, and mass movements; (3) concepts for bringing together the results from experiments with the behaviour of natural systems; (4) experiments for parameterization or the development of soil erosion models
GM3.6/HS13.10 Stochastic sediment transport: from measurements to morphogenesis
Convener: Clement Narteau; Co-Conveners: Eric Lajeunesse , Jens Turowski
Understanding more deeply the motion of sediment is of fundamental importance in hydraulic engineering, fluvial geomorphology and in attempting to estimate future landscape evolution over the next decades and centuries. The recent advent of long, high-quality field and experimental data series makes rigorous statistical analysis possible. This session invites contributions from scientists who try to explore the variability of sediment transport based on observations and a full hierarchy of approaches including experimental studies, partial differential equations, fractal, stochastic and cellular automaton models. One of our focus is on the transfer from numerical geosciences, statistical physics and applied mathematics to geomorphology, helping to tackle the physics of sediment transport as well as the evolution of bed forms and channel morphology. Contributions dealing with bedload transport in mountainous streams, sediment transport in river, coastal and aeolian environment are as welcome and heartily invited.

American Geophysical Union Fall Meeting in San Francisco, 14- 18 December 2009
We would like to announce the following session to be held at the American Geophysical Union Fall Meeting in San Francisco, 14- 18 December. We hope to see many of you there, and look forward to receiving your abstracts.
Session EP18: "Aeolian Surface Processes: Atmospheric Mineral Dust"
Conveners: John-Andrew Ballantine (andy.ballantine@uconn.edu)
Tom Gill (tegill@utep.edu)
James King (james.king@dri.edu)
Natalie Mahowald (nmm63@cornell.edu)
Description: Aeolian sediment processes that include the production,
transport, and deposition of dust are increasingly recognized as a major component of the Earth system. Dust impacts geomorphic surfaces, atmospheric processes, oceanic biogeochemistry, terrestrial ecosystems, and human health. Mineral dust is also a major component of the Martian surface-atmosphere system. This session explores aeolian sediment processes at scales from fine- scale laboratory and field experiments to the representation or observation of dust at scales suitable for global modeling. We seek submissions that describe different approaches to understanding aeolian sediment processes, including laboratory experiments, field-plot measurements, monitoring, satellite observations, tracer back-tracking, atmospheric modeling, and others. Topics relating to either Earth or Mars are welcome. Papers that discuss approaches to reconciling the mismatch in scale between field and modeling studies, quantify the effect of this scale mismatch, or suggest measurements that can reconcile the scale mismatch are especially welcome. In this interdisciplinary session, we intend to highlight how interacting factors and processes of atmospheric sciences, geomorphology, hydrology, ecology, biogeochemistry and land use may promote or suppress aeolian sediment processes, with a particular emphasis on atmospheric dust.

Session Announcement:
In recent years, rapid advances in the application of highly resolved sedimentological and geochemical studies, in combination with various geochronometric techniques and chronostratigraphic tools, have opened up new vistas in the investigation of paleo-records of atmospheric dust loading using aeolian sediment deposits. As these sediments are widespread on the continents, novel multi-proxy investigations enhance our understanding of long-term aeolian dust dynamics and climate variability, linking inter-hemispheric climates on time scales ranging from glacial-interglacial to (sub)millennial.
Innovative contributions are welcome on the application of new and established methodological approaches; results on stratigraphy, geochronology, paleoenvironmental assessments; and geoarchaeology of aeolian deposits in the Northern and Southern Hemispheres. We especially encourage papers that either
(a) utilize high-resolution loess & dust records to reconstruct the timing and dynamics of past synoptic atmospheric circulation patterns on regional and inter-hemispheric scales;
(b) establish precise correlations and define atmospheric mechanisms that link continental loess/dust records with aeolian records in ice cores and/or the oceans; or
(c) address the challenging effort to incorporate the dust proxies of past atmospheric processes into climate models.
This session aims to provide a lively forum to review fundamental scientific steps in the study of aeolian sediment archives and discuss new innovative approaches that enhance our understanding of those records. Submissions by students and young scientists are particularly encouraged!

CAS-TWAS-WMO Forum
International Workshop on “Mineral Aerosol and Its Impacts on Climate and Environment”
17-19 August 2009,Lanzhou, China

1. Scientific Themes
The climate system, comprising of the atmosphere, hydrosphere, cryosphere, biosphere and lithosphere, is dynamic, open, multi-scale, interactive and nonlinear. Dust plays an important role in the climate system because it participates in a number of key feedbacks:
- Radiation: dust is an important type of aerosols. Aerosols influence the energy balance of the climate system through scattering and absorbing radiation and by modifying the optical properties and lifetime of clouds. Aerosols are believed to have a net effect of global cooling in contrast to greenhouse gases.
- Aerosol Chemistry: The optical properties and lifetime of dust and anthropogenic substances can be drastically altered through mixing and chemical reactions. Dust particles are often coated with nitrates and sulphates. North Africa and Northeast Asia are known hot spots where dust, anthropogenic substances and sea salt interact.
- Air Quality: Dust storms can substantially elevate the concentration of airborne particulates in many parts of the world. Many contaminants that pose risks to human health and the environment are associated with dust, including metal, pesticides, dioxins and radionuclide.
- Ocean Biochemistry: Iron is an essential micro-nutrient for phytoplankton growth. The dominant external supply of iron to the ocean is dust transported from arid zones.
- Cryosphere: Snow- and ice-surface albedo is significantly affected by the impurities in snow grains. The impurity concentration in snow and ice and the aging of snow surface depend profoundly on aerosol deposition.
Because of these important feedbacks, the research on dust has been elevated to be among the core subjects of climate system studies. The recent achievements in dust research are significant, but our capability for quantitative dust modelling and prediction remains to be limited for the following reasons.
- It is difficult to accurately determine the key parameters which affect dust fluxes.
- Some fundamental aspects of dust processes are not well understood, e.g. dust emission and deposition.
- There is a serious lack of high-quality and coherent observational data sets for the rigorous validations of dust-emission and dust-deposition schemes.
- Dust storms are mostly associated with certain synoptic and sub-synoptic severe-weather events. Such weather events are also the most difficult to predict using atmospheric models.
In this context, the 8th International Workshop of the CAS-TWAS-WMO Forum will focus on “Mineral Aerosol and Impacts on Climate and Environment”. This workshop will include the following five sessions:
- Session 1: Observations of mineral aerosol and dust storm events
- Session 2: Mechanisms of dust emission and deposition and their parameterizations
- Session 3: Simulation and prediction of regional and global dust cycle
- Session 4: Mineral aerosol radiative forcing and impacts on climate
- Session 5: Paleo-dust and dust impact on the environment
