The effect of global drivers (pH and temperature) and Oil (crude oil conc. 0.5 mg L⁻¹ on larvae of the northern shrimp Pandalus borealis (exposed to oil the day they hatched until 7 d post hatch and followed until all reached stage IV (day 27)) and the green sea urchin Strongylocentrotus droebachiensis (exposed to oil day 8–11(exp. 1 and followed from zygote to 6-arm pluteus) and 23–27 (exp. 2 followed until 8 arm pluteus)) days post fertilisation. (a–c) mortality rate; (d) length; (e,f) body length growth rate; (g) abnormality; (h,i) symmetry index. Control (pH 8.0, 6.7 °C, white), Oil (pH 8.0, 6.7 °C + Oil, dark grey), OA/OW (pH 7.6, 9.5 °C (for shrimp) and 6.7 °C (for sea urchins), ligth grey), OA/OW + Oil (pH 7.6, 9.5 °C (for shrimp) and 6.7 °C (for sea urchins) + Oil, black). Six replicates for each treatment. Values are presented as means ± SD.
