This idea was initially tested in a range of experiments focusing on the [...] that a very similar but natural process was already well underway: especially in the shallow shelf seas, carbon dioxide from the atmosphere was dissolving in the water, making it increasingly acidic. Since

Does sea ice play a particular role in Arctic jellyfish ecology? We evaluate the role of sea ice as a habitat for jellies in order to make predictions on their potential decrease with further sea ice decline [...] DNA analyses. Such interdisciplinary surveys allow us to link distributional patterns of jellies to sea-ice and oceanographic (sub-mesoscale) features. We apply species and community distribution models [...] of jellies in the Arctic food web, their importance for higher trophic levels and their link to the sea-ice trophic pathway will be elucidated with metabarcoding and biomarker studies. We plan to conduct
