Making dry-ice under field conditions
Many of the P³ samples are sensitive to temperature. To stop biological processes deep freezing shortly after sampling is an important step for conserving the samples in the best possible state. So, what, if the next provider of dry ice is 1000 km from your sampling sites? You check internet and learn that you can produce dry-ice yourself! Our hydrologist Jan was ready to take any risks to provide dry ice to Adeline. See for yourself in the short film below. Science is cool! Science is fun!
