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

Updated 2003-07-04

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.

Regions studied

Data availability

References to key publications (or planned publications) and data reports
Results are regularly published in the proceedings of meetings regarding Arctic radioactivity (2000, 2002, 2004). A comprehensive assessment is published in the EU-"REMOTRANS" final report (2004).
Samples/specimens archived in specimen banks?
Specimen banking information

ENEA-MERC Data Bank for info on vertical profiles. ENEA-MERC Historical Archive for spare sediment samples. Sampled and data are stored permanently.

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

Sediment cores taken using a box-corer. Cores are quickly sliced in 1-cm intervals and stored in plastic cans until analysed. Analyses of gamma-emitting natural and anthropogenic radionucles are carried out via high-resolution spectrometry.

QA/QC Information (what QA/QC procedures are implemented, laboratories involvment in QA/QC activities, model verification/validation routines, etc.)

QA/QC are regularly checked analysing Standard Reference Materials (NIST)and participating at international Inteercomparison Exercises (IAEA)
