Bedload Transport in Steep Mountain Streams: Integrating Field Measurements with Flume Experiments

Duration: 2010 – 2011

Bedload transport has high importance within sediment budgets of steep mountain streams. The integration of extended field investigations on fluvial bedload transport and sediment budgets in Erdalen and Bødalen (Nordfjord, western Norway) with advanced field studies at East Creek (Coastal Mountains of British Columbia, Canada) and extended flume experiments on bedload dynamics at the University of British Columbia (UBC), Department of Geography, Canada, is an innovative approach to study mechanisms, controlling factors and rates of bedload transport in steep mountain streams.

SedyMONT: Timescales of sediment dynamics, climate and topographic change in mountain landscapes – Erdalen and Bødalen Site Project

(2008 – 2012)

The approach of this NFR funded project as part of ESF EUROCORES TOPO-EUROPE is the integrated quantitative study of longer-term (Holocene), sub-recent and contemporary sedimentary fluxes, process rates and budgets using a novel combination of advanced methods and techniques. The following key aims of the Erdalen and Bødalen Site Project can be stressed:

  • Analyse how the inheritance of the landscape due to the influence of the Last Glacial Maximum (LGM) has affected process rates over time (paraglacial system)
  • Document changes in process rates over different timescales by combining existing quantitative knowledge on Holocene process rates with newly generated data on sub-recent and contemporary process rates.

The Arctic Chronology Project - (2008-2011)

The Arctic is one of the few remaining petroleum frontiers of the world. Present estimates suggest that the potential recoverable hydrocarbon resources of the Russian offshore area alone are in excess of 100 billion toe, and the major part is within the Arctic shelf. During a recent assessment of the world’s oil and gas resources the U.S. Geological Survey suggested that about 25 percent of the undiscovered oil and gas resources might be found in basins of the high northern latitudes. Hence, exploration is a keyword for future success in this remote area.

SciencePub - (2007-2010) Arctic Natural Climate and Environmental Changes and Human Adaptation: From Science to Public awareness

This is a NFR funded project under the International Polar Year, IPY. The main aims are to:

  • Advance our fundamental knowledge on natural climate and environmental change in the Arctic by improving system understanding and quantifying certain climate components.
  • Advance our understanding of human adaptation strategies to past rapid and large-scale changes in the physical environment.
  • Generate public outreach strategies that will leave a lasting legacy of increased public awareness of the natural environmental systems of the Arctic.
This joint scientific and public outreach project is based on field studies carried out in northernmost Norway, Russia, Svalbard and adjoining seas. It is part of the international IPY cluster APEX. SciencePub is a collaboration between the Geological Survey of Norway (NGU), the universities of Tromsø (UiT) and Bergen (UiB), the Norwegian University of Life Sciences (UMB), the Norwegian Polar Institute (NPI), the Science Centers in Tromsø, Trondheim and Bergen (SC), and the Oslo University College, Faculty of Journalism (UOC). The project is headed through the Geological Survey of Norway with Eiliv Larsen as project leader.

GLACIPET - (2005-2009) Ice ages: subsidence, uplift and tilting of traps - the influence on petroleum systems

The main aims of the project are to model isostatic response of Cenozoic glaciations, sedimentation and erosion on parts of the Norwegian continental shelf, and to constrain consequences for petroleum systems. Data input for modeling is collected through three scientific sub-goals that are to:

  • Obtain more complete knowledge on timing and extent of glaciations through the Plio-Pleistocene.
  • Improve understanding and quantification of glacial depositional and erosional processes.
  • Expand knowledge on interaction between the Fennoscandian, the Barents Sea, and Kara Sea ice sheets and their crustal influence through the last glacial cycle.

The project is carried out in the Barents Sea and the northern North Sea regions. This is partly due to economic interests in the areas, but also because the first area is characterized by uplift through the late Cenozoic, while the second has experienced subsidence over the same period of time.

Detects biofilm variability stable and mobile channel pavement patterns in steep bedload streams in cold environments?

Duration 2008-2009

Bedload transport has high importance within sediment budgets of steep mountain streams. Main goals of new research are (i) the better quantitative detection of the mobilised depth of the active channel pavement, (ii) the improved detection of stable and mobile channel units. Biofilm analysis shall provide answers about frequencies of sediment mobilisation and vertical extent of the active/mobilised channel pavement in bedload streams by analysing benthic algae and bacteria as well as biofilm on sampled substratum.

GEOS – pre-Quaternary landscape development in the Oslo region.

In this project we examine the long-term landscape development in southern Norway and in particular in the Oslo region. South Norway has been characterized as a stripped etch-surface, heavily influenced by Caenozoic weathering and subsequent erosion. We map and characterize pockets of chemical weathering remnants, reconstruct palaeo-river networks and link these findings to Caenozoic (glacial- and non-glacial) erosion.

Geo-tourism: Geological information for the tourism industry

Magnificent and unique landscapes are among the most important tourist destinations in Norway and the story about how Norwegian landscapes came about geologically is an important part of the tourist experience.

The Geotourism-projects aim to produce geological information (publications, web pages etc.) in selected areas for visitor centres, museums and for the education of tourist guides. This information enforces Norwegian landscapes as tourist destinations. The projects are carried out in co-operation with external participants.

SEDITRANS - (2004-2007) Past and current valley-to-fjord sediment transport - processes and products: A transect from Jostedalsbreen to Nordfjorden, western Norway.

Valleys and fjords may be considered as conduits for sediment transport from the mountain areas to the ocean. The research project targeting the Nordfjorden valley - fjord system in western Norway aims at:

  • Identifying recent sedimentary processes and determine their relative importance and spatial variability along a mountain-valley-fjord profile
  • Determining the distribution of sediments from the last deglaciation to the present and identifying the controlling factors
  • Constructing qualitative and quantitative models for the glacier-valley-fjord sedimentary system during deglacial and interglacial phases
  • Providing basic knowledge on erosion-, transport- and sedimentary processes of glaciated coastal regions as input for models on glaciated margin development and for the understanding of glacial depo-centres along the Norwegian margin,
  • Providing data and knowledge on fjord - valley deposits in order to contribute to optimal planning
  • Modeling, analyzing and visualizing fjord - valley geology based on various and large datasets using modern 3D/GIS tools.

NORPAST-2 - (2003-2006) Past Climate of the Norwegian Region

The project aims to advance the knowledge of patterns and variability of past climate in the Norwegian Region (Norway and adjoining continental margin and fjords) and to contribute to the understanding of climate forcing factors. The studies focus on quantitative climate reconstructions during the last deglaciation, the Holocene and the Recent Past, by investigating a limited number of high-resolution sites from terrestrial and marine archives; by improving paleoclimatic proxies; and by synthesising existing and new data. The project is divided into five related modules:

  • Patterns and frequencies of natural climate variability on decadal to seasonal time scales during the last millennium
  • Patterns andfrequencies of natural climate variability on decadal to millennial time scales during the lateglacial and Holocene
  • Ice sheet / ocean interactions during abrupt climate changes
  • Development, improvement and testing of proxy methods for climate reconstructions
  • Correlation and synthesis of results.

The NGU group contributes to all modules and has the leadership of module 3.
