The Catlin Arctic Survey scientists wanted to see what impact increased ocean acidification might have on a type of zooplankton, copepods. To do this, they trawled for copepods through a hole in the ice and placed them in experimental batches. These experimental batches were exposed to different levels of pH simulating both current and predicted scenarios. After seven days, the batches were examined to see how many of the copepods had survived in each scenario and analyse the impact that future acidification might have on zooplankton, the foundation of the Arctic food web.
