Strong quake, small tsunami

GEOMAR scientists publish unique data set on the northern Chilean subduction zone

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

Probiotic approaches could protect corals against heat stress

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.
