Temperatures around the world continue to rise – and the North Sea is no exception. Yet, in addition to this gradual warming, increasingly frequent and intense heat events also have consequences for marine organisms. Researchers at the Marine Station Helgoland, a research facility of the Alfred Wegener Institute, have quantified the frequency and intensity of these heatwaves along with their repercussions for plankton. They have also conducted an experiment that exposed the North Sea plankton community to different future warmer scenarios, both with and without heatwaves. The researchers found that gradual warming causes significant shifts in the species spectrum. When heatwaves are added, however, these alterations are amplified. The results have been published in three publications, most recently in Limnology and Oceanography.

New international research from Tulane University and published in Nature Geoscience is the first study to demonstrate global-scale patterns in how El Niño-Southern Oscillation (ENSO) influences mangrove growth and degradation. Previously, impacts had only been documented at individual sites, such as a dramatic die-off in northern Australia in 2015 when more than 40 million mangrove trees perished along a 1,200-mile stretch of coastline. 

The puzzling behaviour of Titan’s atmosphere has been revealed by researchers at the University of Bristol for the first time.

A world-first multi-sensor detection of an intense gamma-ray flash has been observed by researchers from The University of Osaka, when two lightning leaders collided. Observations across a wide radiation spectrum enabled precise measurement of the electric current produced during this extreme event, and demonstrated that the gamma-ray flash preceded the collision of the lightning leaders between the thundercloud and the ground.
