Report: Surveillance of the Lower Saxon coast – II. Special investigations 1994’
Description
“In routine monitoring, it is excluded to keep all components of the inanimate and lively environment under control, as well as all civilizational influencing factors with continuous measurements. Especially in the last decade, cases of ecological changes occurring unexpectedly in the non-routine-measured ecosystem components have accumulated. [...] The special investigations shall form part of the ‘monitoring of coastal waters of Lower Saxony’; the results will be included in the federal/state trade fair programme and in the future in the TMAP. The results communicated here complement the results of routine investigations for the monitoring of coastal waters of Lower Saxony for 1994, as reported in Service Report 26/1995.
The following special investigations were carried out in 1994:
Sediment studies: Monitoring of anoxic sediment surfaces in the Norderney Wattland (as diploma thesis THIESSEN 1992);
Pollutants in organisms: Heavy metal monitoring in selected wattage organisms;
Pollutants in organisms: Loading of the clasp (Mya arenaria with heavy metals);
Pollutants in organisms: Exposure to mussel in the coastal waters of Lower Saxony with persistent organic chlorine substances;
Pollutants in organisms: The organozinn load and histopathology of mussels (Mytilus edulis) of the Lower Saxon coast;
Pollutants in organisms: Investigation of beach snails (Littorina littorea) for organozinn compounds and other pollutants;
Biological inventory monitoring: Summer mass occurrence of benthic green algae;
Biological inventory monitoring: Mapping of seaweed stocks;
Biological inventory monitoring: Mapping of the mussel stock in spring 1994;
Biological inventory monitoring: Growth communities of artificial hard substrates – a comparison with previous surveys;
Biological inventory monitoring: The disappearance of the corrugated snail (Buccinum undate) as a result of Imposex;’
