The Institute of Marine Research, Bergen, samples about 10 000 station
s annually which are used for monitoring and assessment of marine envi
ronment and marine resources, Results from these activities are often
presented in maps showing either horizontal or vertical distribution o
f the observed parameters, This paper gives a very brief summary on ho
w maps are used at the Department of Marine Environment for presenting
geographical distribution of different parameters. The main areas of
research activities are within physical, chemical and biological ocean
ography, and examples are given from numerical modelling, zooplankton
research and pollution of sediments.
