Subprogramme H.1. Measurement and Assessment of Radionuclides in the Marine Environment

Rationale:
The marine environment has been widely impacted by nuclear activities and the measurement and assessment of this impact requires further investigation. Member States need information on the present levels of radioactive and stable isotopes in the marine environment in order to evaluate trends, to study oceanographic processes and climate change, and to predict future conditions. This assessment requires the quantification of natural and anthropogenic sources of radionuclides in the world's oceans and seas, computer modelling of the dispersion of radionuclides, and water and sediment dynamics studies. Nuclear and isotopic techniques provide tools to investigate oceanographic processes and marine contamination on a quantitative basis and to address the problems of coastal zone management. Demand driven programmes of assistance to Member States in the quality management of laboratories, capacity building, design and implementation of monitoring programmes, and the provision of training will further improve the understanding and protection of the marine environment. The Agency acts in the framework of the United Nations Global Programme of Action for the Protection of the Marine Environment from Land-Based Activities (GPA) as a clearing house of information on radioactive contamination in the marine environment, and provides advice and assistance on marine radioactivity to Member States (in Europe, North Africa, East Asia, Latin America, South Pacific region), as well as to regional and international bodies, such as the Oslo-Paris Commission for Protection of the Marine Environment of the NE Atlantic (OSPAR), the Helsinki Commission, the Barcelona Convention, and the Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP).


This subprogramme concentrates on marine radioactivity assessment and contamination studies in the coastal regions and open seas with technical assistance to Member States, on the provision of radionuclide data, on climate change studies, on implementation of quality assurance programmes in Member State laboratories and provision of reference materials, on training and capacity building, and on the development of methods for analysis of radionuclides in the environment in response to emergencies.



Objective:
To enable Member States to assess current and future levels of radioactive and stable isotopes in the marine environment as affected by processes in the water column and sediment, efficiently manage marine coastal zones and understand climate change phenomena.



Project H.1.01: Worldwide marine radioactivity studies in oceans and seas

Main outputs:
The project will result in: an improved relational database - the Marine Information System (MIS) - containing information on the distribution and concentrations of radioactive and stable isotopes in the marine environment and on oceanographic parameters; technical guidelines on the development of national and regional databases to evaluate present levels of radioactive and stable isotopes in the marine environment and predict future conditions and trends in contamination of the marine environment; guidance to Member States for a better understanding of marine processes responsible for future contamination of the marine environment; and proceedings of an international conference on environmental isotope studies.
Duration: 2002-2005


Project H.1.02: Contamination studies in selected coastal zones (in co-operation with UNESCO)


Main outputs:
The implementation of this project will result in: a package of tools to identify and quantify submarine groundwater discharge using nuclear techniques; guidelines for quantitative evaluation of the contribution of submarine groundwater discharge to the water balance in coastal zones and to the contamination of coastal waters by heavy metals and organic compounds; improved techniques for the investigation of water column processes and sediment dynamics in coastal zones; and effective integrated management of coastal zones by Member States.
Duration: 2002-2005


Project H.1.03: Climate change studies using isotopic records in the marine environment (in collaboration with ICTP, Trieste)

Main outputs:
The project will produce: a package of isotopic tools for environmental change investigations based on model case studies developed during the project; sea temperature records over the past few hundred years and information on past climate changes (2006); Ocean General Circulation Model for computer modelling of the distribution of isotopes in the oceans, atmosphere-ocean coupling and climate change studies (2007); and trained personnel in the application of nuclear and isotopic methods in climate research.
Duration: 2004-2007


Project H.1.04: Analytical Quality Control Services for marine radioactivity studies

Main outputs:
The main outputs of the project will be: certified reference materials for the analysis of radionuclides in marine samples; procedures for regional and global intercomparison exercises and proficiency tests; guidelines for the implementation of quality assurance/quality control programmes in Member State laboratories to strengthen their reliability; trained personnel (through the TC programme) in quality assurance/quality control programmes.
Duration: 2002-2005


Project H.1.05: Development of methods for analysis of low level radionuclide concentrations in the environment in response to emergencies

Main outputs:
The project will result in: methods for low level analyses of radionuclides; guidelines for sampling, sample pre-treatment, radiochemical separation and spectrometric analyses; assistance in the use of sensitive and reliable radioanalytical techniques for the analysis of radionuclides in the marine environment; and trained personnel (through the TC programme).
