Abstract

In many coastal environments over-fertilization is an impediment to fishing and tourism. The Gulf of Finland (Baltic Sea) is one example of where the environmental conditions have not improved in spite of lower land input of nutrients. The reasons for this are investigated in an ongoing project in which a unique combination of traditional and novel techniques is employed. Acoustic and optical sensors are used for long term measurements of currents, sediment resuspension and oxygen variations. Autonomous bottom landers are operated to asses the effects of resuspension and to make detailed investigations at the sediment-water interface using e.g. a "Planar Optode".
