How do light and darkness change in the ocean? This question is at the heart of two major European projects, ISOLUME and ALANIS. They have now begun their work at a kick-off event in Hamburg attended by around 50 researchers from 13 countries.

Today, the two-day kick-off meeting for the international “Joint Action on Changing Marine Lightscapes” launched by JPI Oceans started in Hamburg with more than 50 participating researchers. The initiative aims at a better understanding of changing light conditions in the ocean and how this impacts marine ecosystems. Two projects are taking up work under the umbrella of a joint knowledge hub. The ISOLUME project coordinated by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) focuses primarily on ocean darkening; the ALANIS project, led by the Helmholtz-Zentrum Hereon, mainly addresses nocturnal light pollution.
