Tropical coral reefs lose up to two thirds of their zooplankton through ocean acidification. This is the conclusion reached by a German-Australian research team that examined two reefs [...] the seabed, lowering the water's acidity to a level, which scientists predict for the future of the oceans. The researchers believe that the decline in zooplankton is due to the loss of suitable hiding places [...] places. It results from the changes in the coral reef community due to increasing acidification. Instead of densely branched branching corals, robust mounding species of hard coral grow, offering the z

exactly the pain threshold regarding envi- ronmental changes is for large marine algae. How much ocean acidification can a species tolerate? How well can it cope with rising water tempera- tures? How much do [...] but with an increased supply of carbon dioxide (CO2) at the same time, as in the case of ocean acidification, this can be compensated.” The biologist is now examining how sensitive the kelp forests are [...] can only be examined on site but under water. For this we need the skills of ocean scientific divers combined with an ocean scientist. Anyone who wants to get up really examine the medium and its underwater

Ocean Acidification
In November 2017, the German research network on ocean acidification BIOACID (Biological Impacts of Ocean Acidification) reaches its conclusion after eight years of extensive in [...] from 20 German institutions clearly indicate that ocean acidification and warming, along with other environmental stressors, impair life in the ocean and compromise important ecosystem services it provides

vulnerable to ocean acidification. The increasing amount of carbon dioxide in the atmosphere leads to an increased absorption of CO2 in the cold waters of the polar oceans and enhances the acidification there
