KARTLÄGGNING AV TOTALT SUSPENDERAT MATERIAL FRÅN GLOMMA ÄLVEN MED SATELLIT DATA / Remote Sensing of Total Suspended Matter from the Glomma River in the Skagerrak
In this study remote sensing techniques have been used to quantify total suspended matter (TSM) in the red part of the electromagnetic spectrum. Data from NOAA-AVHRR are used to demonstrate the temporal change of the Glomma river in the northeastern part of the Skagerrak area, whereas LANDSAT-TM shows the detailed spatial coverage. The technique described by Tassan (1987) is applied to TM to calculate TSM. The results indicate that the areal coverage of the river plume has an exponential decrease with increasing TSM, which varies from 35 to 10 mg/1 in May 13, 1988. The qualitative interpretation of the plume coverage of the archipelago shows strong dependence on wind, currents and river flow volume. Aeral coverage of 200 km2 does occur and may change its size within 24 hours.
