Environmental monitoring - coastal, offshore and freshwater
 | Public awareness and government requirements to assess environmental conditions have led to environmental surveys to monitor the effects of pollutants on the marine environment.
IRIS Biomiljø holds significant experience in developing research activities, conducting field work, sample analyses and interpretation of data.

Experience from a wide range of geographical regions including tropical and Arctic environments.
In environmental monitoring the highest ecological relevance is generally obtained when the measurements are done in wild living organisms.
A problem to overcome with wild caught fish is that we know very little about their history: they are free swimming and migrate. Seen from the other side, traditional laboratory experiments have problems to represent natural conditions found in the field. Thus, in the case of industrial effluent monitoring the best available practice at the moment has been to compromise by using genetically homogeneous (farmed) fish and bivalves deployed in cages to monitor exposure and biological effect of discharges into the water column.
IRIS Biomiljø has gained experience with several kinds of caging applications. Different marine organisms have been caged, like pelagic fish, mussels and scallops. The effect of different kinds of chemical discharges has been monitored: like PAH from aluminum smelters, PAH and chemicals in produced water, drill mud discharged in the water column or as piles on the sea floor. |
