2. Hydrology and water currents in the inner part of Kongsfjord in front of Kongsbreen Glacier

The aim of this project is to study the physical oceanography of the sea in the area where Kongsbreen glacier get in touch with the sea in the inner part of Kongsfjord. In particular the project aims:  to characterise temperature and salinity of water masses in the inner part of Kongsfjord close to Kongsbreen Glacier  to characterise major fresh water outflow from Kongsbreen glaciers to the sea in the inner part of the fiord  to collect time series if seawater currents in-out from the inner part, temperature and salinity patterns for one year from summer 2001 to summer 2002.  to collect a one year time series of sea level changes by an automatic self recording depth gauges deployed close to the base.

3. Role of organic and inorganic particles in the mobility of radionuclides in the Kongsfjord-Krossfjord system (MORAK)

The aims of the project are: - to evaluate the fluxes of radionuclides in the water column and their accumulation in the sediment, on a short-time scale; - to determine the C/N and delta13C-delta15N ratios in suspended and sedimentary matter, and test their use as tracers of origin, composition and transformation pathways of organic particles. The selected study area is the Kongsfjord-Krossfjord system, Svalbard, considered as representative test-site for studying processes occurring in Arctic fjords. The focus of the project will be on the processes occurring at the glacier-sea interface, where enhanced lithogenic and biogenic particle fluxes are reported in summer. Specific methods will be used to trace the particle sources. The rate of accumulation-resuspension processes will also be investigated from the inner fjord to the outer continental shelf.

4. Submarine Operational And Research Environmental Database (SOARED)

The Submarine Operational And Research Environmental Database (SOARED)is comprised of a fixed relational environmental database using unclassified data collected during the Science Ice Exercises (SCICEX) during the past several years. It also includes publicly accessible gridded historical sound velocity, temperature and salinity data from 1900 from the US National Oceanographic Data Center. This project is a demonstration system to show ways to retrieve and analyze sound velocity, temperature and salinity profiles, bathymetry and ice thickness data using a mouse-driven GIS-based query.

6. A 30-Year Sea Ice Data Set from Satellite Microwave Radiometers

The project consists of two parts: the generation of a data set of sea ice extents and areas, and associated scientific analyses. The objective of the first part is to produce a 30-year, research quality sea ice data set for climate change studies. The data set will build on an existing 18-year data set derived from satellite passive-microwave observations and currently archived at the National Snow and Ice Data Center in Boulder, CO. We will extend this data set by using historical data from the 1970's from the National Ice Center and new data from DMSP Special Sensor Microwave Imagers and the upcoming EOS-PM Advanced Microwave Scanning Radiometer. These data sets will be cross-calibrated to ensure a consistent 30-year data set following methods developed earlier and based on matching the geophysical parameters during periods of sensor overlap. The principal products will be Arctic and Antarctic sea ice extents and areas, derived from sea ice concentration maps. The second part of the proposal will center on the analysis and use of the 30-year data set. The science objectives are (1) to define and explain the hemispheric, regional, seasonal, and interannual variabilities and trends of the Arctic and Antarctic sea ice covers and (2) to understand any observed hemispheric asymmetries in global sea ice changes. Hemispheric sea ice cover asymmetries have been found in the existing 18-year record and have also been suggested from some model experiments simulating future conditions assuming a gradual increase in atmospheric CO2. We will examine the proposed 30-year record to determine the degree and nature of the hemispheric asymmetry in it and to place the sea ice observations in the context of other climate variables through comparisons with simulations from the NOAA Geophysical Fluid Dynamics Laboratory and Hadley Centre climate models.
