SEDIMENTTRANSPORT

Forkortet:
This Fourth ESF SEDIFLUX Science Meeting & First Workshop of I.A.G./A.I.G. SEDIBUD Workshop builds on three previous ESF SEDIFLUX Science Meetings held in Saudarkrokur (Iceland) in June 2004, Clermont-Ferrand (France) in January 2005 and Durham (UK) in December 2005. The theme of the Meeting is "Source-to-Sink-Fluxes and Sediment Budgets in Cold Environments". The Meeting is split between scientific presentations and workshop discussions focused on the principle working groups of ESF SEDIFLUX. The key aims of SEDIFLUX are to provide a framework for integrated, multidisciplinary research on sediment fluxes, sediment transfers, sediment budgets and climate change and to foster research collaboration between researchers in Europe and globally.

This First Edition of the SEDIFLUX Manual is an outcome of the European Science Foundation (ESF) Network SEDIFLUX - Sedimentary Source-to-Sink-Fluxes in Cold Environments (2004 - 2006) (http://www.ngu.no/sediflux, http://www.esf.org/sediflux). The development of this publication has been based on four ESF SEDIFLUX Science Meetings, which were held in Saudarkrokur (Iceland), June 18th - 21st, 2004, Clermont-Ferrand (France), January 20th - 22nd, 2005, Durham (UK), December 16th - 19th, 2005 and Trondheim (Norway), October 29th - November 2nd, 2006.
The aim of this Manual is to provide guidance on developing quantitative frameworks for characterising catchment (field-based) sediment budget studies, so that: (1) baseline measurements at SEDIFLUX/SEDIBUD key test catchments are standardised thus enabling intersite comparisons, and (2) long-term changes in catchment geosystems as related to climate change are well documented. The main focus is on non-glacial processes, although within the context of glacierised catchments glacial sediment transfer processes are assumed as inputs/outputs of the periglacial / paraglacial system.
This First Edition of the SEDIFLUX Manual will be further developed within the I.A.G./A.I.G. Working Group SEDIBUD - Sediment Budgets in Cold Environments (http://www.geomorph.org/wg/wgsb.html).

This Second Workshop of the I.A.G./A.I.G. Working Group SEDIBUD (Sediment Budgets in Cold Environments) builds on four previous ESF SEDIFLUX Science Meetings held in Saudarkrokur (Iceland) in June 2004, Clermont-Ferrand (France) in January 2005, Durham (UK) in December 2005 and Trondheim (Norway) in the end of October/beginning of November 2006.
A first kick-off Meeting of the new I.A.G./A.I.G. Working Group SEDIBUD took place during the third ESF SEDIFLUX Science Meeting in Durham, and the fourth ESF SEDIFLUX Science Meeting in Trondheim was organised in combination with the first I.A.G./A.I.G. SEDIBUD Workshop.
The theme of this Second I.A.G./A.I.G. SEDIBUD Workshop is Sediment Fluxes and Sediment Budgets in Changing High-Latitude & High-Altitude Cold Environments. The Workshop is split between scientific paper and poster presentations, presentation and discussion of SEDIBUD key test sites, discussions within defined work groups and a guided field trip to Kärkevagge.
This workshop will address the key aim of SEDIBUD to discuss Source-to-Sink-Fluxes and Sediment Budgets in Changing Cold Environments. Major emphasis will be given to consequences of climate change, scaling issues and source-to-sink correlations.
Central issues will be the presentation and discussion of the SEDIFLUX Manual (First Edition), the selection of SEDIBUD key test sites, the discussion and development of the SEDIBUD metadata database, the discussion of relevant SEDIBUD science questions and the development of further ideas to extend the scientific activities within SEDIBUD in a global framework.

Climate change affects all Earth surface systems but with the arguably
greatest impact in high-latitude and high-altitude cold environments. In these areas, climate change shapes earth surface processes not just by altering vegetation cover and human activities but also through its impact on frost penetration and duration within the ground surface layers. All of these factors influence patterns of erosion, transport and deposition of sediments and related fluxes (e.g., nutrients, solutes, carbon).
It is a challenge to develop a better understanding of how these factors combine to affect sedimentary transfer processes and sediment budgets in cold environments. Our baseline knowledge on the erosion, sedimentary transfer and depositional processes operating within Holocene and contemporary climates and as landscape systems evolved and under given vegetation covers, forms our basis for predicting the consequences of predicted future climate change and related vegetation cover changes. However, much of this information is limited in terms of spatial and temporal coverage and needs to be extended and consolidated. Only when we have these reliable models response to landscape and climate change we will have fuller understanding of probable future changes to these regions.

Central issues of this Fourth SEDIBUD Workshop are:
- Scaling issues within sediment budget studies
- The application of new techniques within sediment budget studies
- Modelling
- Data management

Sandwaves are common on many continental shelves and slopes around the w<Jr'l<t.l()ften their dynamic nature poses challenges for maritime installations such as pipelines and other constructions on the seafloor. Sand waves and sandwave fields are indicative of strong currents causing erosion, sediment transport and deposition on the seabed. Several sandwave fields have recently been identified on the Norwegian continental slope in the Eggakanten mapping area, SW Barents Sea through the MAREANO programme (www.mareano.no). It is in this Eggakanten area that we investigate sandwaves further in the present project, with a view to raising the understanding of sandwave evolution and sand transport along the Norwegian continental slope.
