Flagship
Ocean Acidification
Funding Source

Summary of Results

We conducted an experiment to assess the effect of pCO2 on Calanus finmarchicus and glacialis. The levels selected were framed by predicted increases over the next 100 years. There was no effect of pCO2.

For the Management

The project management went according to plan.

Budget in accordance to results

As planned.

Could results from the project be subject for any commercial utilization
No
Conclusions

Calanus spp. populations are unlikely to be strongly affected by ocean acidification.
