Brown algae could slow climate change. An artist depicts the slippery climate protectors.

Brown algae as a climate protector is the focus of an exhibition in Bremen.“Algae in the sea can remove large amounts of carbon dioxide from the atmosphere,” said the House of Science. French artist Sarah Brik has taken up this phenomenon and has artistically edited images of algae. The exhibition “Light Streams – Light Streams” will open on Wednesday afternoon (5pm).

A team from the Max Planck Institute for Marine Microbiology in Bremen is searching for slippery climate protectors: Brown algae use carbon dioxide during growth, according to research findings. The algae also use greenhouse gases to form a sugary slime that is difficult to decompose and can remain in sediments for centuries.

Brown algae are multicellular algae that are mostly found in the sea. These include seagrasses, complex kelp, and the bladderwort (Fucus vesiculosus) examined in the study, which is widespread in the North Sea, Baltic Sea, and North Atlantic. The team writes that brown algae fix more carbon per unit area than forests on land. Farms where algae are grown, harvested, and used could therefore serve as a measure against climate change.

Brick processed the research team’s images for the exhibition: “She dips the prints in water, cleans them with ink and depicts the air and water flows with reflective materials in follow-up images using flash,” says the House of Science. The Max Planck Institute for Marine Microbiology and the Center for Marine Environmental Sciences at the University of Bremen are providing scientific support for the project. The exhibition can be seen at the Haus der Wissenschaft until October 28.
