Summary of Results

We conducted an experiment to assess the effect of two temperature levels and three pCO2 levels on Calanus finmarchicus. The levels selected were framed by predicted increases over the next 100 years. Although the data are still being analysed, there appeared to be no effect of pCO2 at either temperature. As expected, there were clear effects of increased temperature.

Conclusions

Data is still being analyzed. Nonetheless, it is safe to say that temperature increase consistent with global climate change predictions for the Arctic is a more important driver for Calanus spp. populations than is ocean acidification.
