Activities
Benthos monitoring is now established as an important part of most European
marine monitoring and surveillance programmes.
The traditional way to sample the marine environment is to place probes,
or sensors in the water or in the sea bed and directly measure physical
and chemical variables such as:
temperature, salinity, conductivity, density, light attenuation, Secchie
depth, fluorescence, oxygen saturation, pH, alkalinity.
Samples for chemical analysis are usually taken with water bottles or
pumping systems and are taken to laboratories, such as the Marine Ecology
Laboratory, for further analysis of the nutrient content, such as phosphate,
nitrate, ammonium, silicate and many others.
The same procedures are carried out in respect of contaminants and toxicants
in sea water. The analysis of sediments is still in the progress of further
scientific development.
