A bleached reef-building coral of the genus Porites. These coral species are important builders of most reefs in the entire Indo-Pacific region. Due to increasingly prolonged heat waves and more extreme temperatures, corals and thus marine ecosystems in the tropics are already on the verge of collapse. Photo: A. Roik

Pyrosomes - enigmatic marine inhabitants with an important role in the Cabo Verde ecosystem

New study led by GEOMAR provides fascinating insight into a largely unknown marine life form

Change in the leadership of the GAME programme

Prof. Dr. Arne Körtzinger takes over as scientific supervisor from Prof. Dr. Martin Wahl

Zooplankton ingestion of microplastic reduces grazing pressure and permits more algal growth. More algal growth leads to more organic particles sinking out of the surface ocean. When these extra particles sink, they are consumed by bacteria, which leads to an additional loss of oxygen in the water column. Graphics modified from Kvale et al. 2021.

Microplastics affect global nutrient cycle and oxygen levels in the ocean

GEOMAR study points to possible major changes in the marine ecosystem
