The Arctic Jellies (ARJEL) project: Investigating the impact of gelatinous zooplankton communities on changing Arctic ecosystems
Gelatinous zooplankton are known to be major drivers of ecosystem changes. Increases in jelly biomass, referred to as “jellification”, have been observed in several marine ecosystems, causing, amongst others, the collapse of major fisheries. For the Arctic region, abundance data on jellies are virtu...

Gelatinous zooplankton are known to be major drivers of ecosystem changes. Increases in jelly biomass, referred to as “jellification”, have been observed in several marine ecosystems, causing, amongst others, the collapse of major fisheries. For the Arctic region, abundance data on jellies are virtually non-existent, impeding our ability to detect changes of a similar magnitude. To better understand the role of jellies in the Arctic seas, the Helmholtz Young Investigator project ARJEL (2019-2025), will combine the most recent technologies in optics, acoustics, and environmental DNA analyses. Integrative field surveys will allow us to link distributional patterns of jellies to sea-ice and oceanographic features.
