| Abstract |
The three marine planktonic diatoms Skeletonema costatum (clone Skel-5), Thalassiosira pseudonana (clone 3H) and Phaeodactylum tricornutum (clone Pheo) were grown in dialysis cultures in outdoor tanks exposed to seawater extracts of Ekofisk and Statfjord crude oils and to sea water collected below an artificial oil spill with Statfjord crude oil at Haltenbanken. The effects on growth rate and photosynthetic capacity were similar to those observed in laboratory batch cultures, and so was the difference in sensitivity among the algae, with Skeletonema being the most sensitive species. The in situ dialysis culture technique served well as a link between the laboratory and the field situations, and may be used as a monitor of phytotoxic effects in an oil spill situation (DBO). |
