The total discharge of produced water in the Norwegian sector of the North Sea is expected to increase to 90 × 10 6 m 3 within the year 2000, with nearly all of this originating from oil production. Produced water from three oil fields in this secto

Apical elonggation of five intertidal fucoids (Pelvetia canaliculata (L.) Dec. et Thur., Ascophyllum nodosum (L.) Le Jol., Fucus spiralis L.,Fucus vesiculus L. and Fucus serratus L.) was measured during exposure to different salinities. The response

The fccal pellet production of Abra alba was measured during exposure to different concentrations of diesel oil, drilling muds with different base fluids, oil-based cuttings and barite. For oil-based drilling muds a curvilinear regression ( y = ax +

Mature Mytilus edulis were exposed to copper (concentration range 1–40 μg l ) and microencapsulated diesel oil (concentration range 200–5,000 μg l ) for 30 days and induced to spawn. EC 50 values for spawning frequency were approximately 2 μg

The increase in length of Pelvetia canaliculata (L.) Dec. et Thur., Fucus spiralis L., F. vesiculosus L., F. serratus L., and Ascophyllym nodosum (L.) Le Jolis was measured in various concentrations of lead, cadmium, and mercury during a period of 9

In Pelvetia fastigiata (J. Ag.) DeToni the diurnal variation in length growth-rate distinctly follows the variation in irradiance, both in November–December and in March, and a highly significant correlation is found between these two variables ( r

The increase in length of apices of Ascophyllum nodosum (L.) Le Jolis was measured in paired combinations of Cu, Hg, and Zn. Significant antagonistic effects appeared with exposure to Cu + Zn after 3 days (P < 0.001), and with Hg and Zn after 4 days

The growth of Pelvetia canaliculata (L.) Dec. et Thur., Fucus spiralis L., Fucus vesiculosus L. and Fucus serratus L. is measured in various concentrations of copper (12–970 μg/litre) during a period of ten days. Significant reductions in growth w

Heritabilities are estimated for growth in shell length in larvae and juveniles of Mytilus edulis, based on a nested design, involving 27 families (27 females, 9 males). Very high heritabilities (hD2 > 0.6 and hS2 > 0.5) were found for growth in both

The variation in apical growth rate between different plants of Ascophyllum nodosum (L.) Le Jolis was measured during different seasons and under different temperature regimes. Under laboratory conditions, different plants sampled at the same localit
