- Introduction:
- About the importance of exploring the Baltic Sea and getting acquainted with the research vessel Aranda
- Study 1: Effects of pH decrease on copepods
- The Baltic Sea ecosystem is stressed by the eutrophication and climate changes. The seas are getting increasingly acidic. This means a decrease in the pH of sea water. How do these changes affect the reproduction and survival of copepods, the central link in the foodweb?
- Study 2: Effects of Marenzelleria on the Baltic Sea sediments
- Due to eutrophication, in some places of the Baltic Sea bottom, the oxygen level is very low and the amount of nutrients accumulated into the sediment is high. It gives an opportunity to species, like Marenzelleria to win space. Marenzelleria is an invasive worm that lives in the bottom layers and burrows networks of tunnels in the sediment. Burrowing reoxygenates, but what happens to the accumulated nutrients?
- Study 3: Can copepods use cyanobacteria as food?
- Eutrophication and climate changes have favored the increase of cyanobacteria in the Baltic Sea during summer time. How does this affect the possibility of copepods to find enough food? Do copepods eat cyanobacteria, though it may be toxic? Are there differences in this matter between Acartia bifidosa and Eyretymora affinis, two of the dominant copepod species in the Baltic Sea.
