Figure 5.6. Distribution of stations carried out during cruise 0671013-1 with water sampling and subse- 
quent filtration for chlorophyll-a determination (red dots). 
The chlorophyll-a concentrations measured in the laboratory serve 1) as a rough measure of 
ohytoplankton biomass and 2) are used for comparison with the chlorophyll-a concentrations 
determined by remote sensing (ground truthing). 
5.9 Sampling of Radionuclides 
Sampling of radionuclides is based on several legal and regulatory provisions arising from the 
Radiation Protection Act, the Radiation Protection Ordinance, the General Administrative Reg- 
ulation relating to the /ntegrated Monitoring and Information System (IMIS), the /MIS Compe- 
tence Regulation, the 1957 Treaty establishing the European Atomic Energy Community, the 
Marine Strategy Framework Directive (MFSD) and the Maritime Shipping Responsibilities Act. 
In addition, there are international obligations under OSPAR and HELCOM.
