15 de ago. de 2018 · Some of the recently observed marine heatwaves revealed the high vulnerability of marine ecosystems 3,4,5,6,7,8,9,10,11 and fisheries 12,13,14 to such extreme climate events.
When ocean temperatures are exceptionally high in a specific area for an extended period of time, it has the potential to affect the biology and chemistry of an ecosystem. Marine heatwaves are events where temperatures are unusually high for an extended period. One commonly used metric defines a marine heatwave as an event where temperatures ...
19 de oct. de 2021 · MHWs can be considered as the equivalent of underwater fires, and similarly to extreme weather events on land, have been shown to have devastating consequences for marine biodiversity and ecosystems, and the related fisheries and aquaculture industries. Our latest IUCN Issues Brief, explaining MHWs, has just been published. Photo: IUCN GMPP ...
20 de abr. de 2022 · Marine heatwaves (MHWs)—periods of exceptionally warm ocean temperature lasting weeks to years—are now widely recognized for their capacity to disrupt marine ecosystems 1,2,3.The substantial ...
28 de jul. de 2020 · Marine heatwaves (MHWs) are prolonged extreme oceanic warm water events. They can have devastating impacts on marine ecosystems — for example, causing mass coral bleaching and substantial ...
30 de ago. de 2018 · However in marine ecosystems, heat waves alone are recognised as obvious and dramatic drivers of extensive coral bleaching and mortality 19,20,21. Long-term, ...
Climatic extremes are becoming increasingly common against a background trend of global warming. In the oceans, marine heatwaves (MHWs)—discrete periods of anomalously warm water—have intensified and become more frequent over the past century, impacting the integrity of marine ecosystems globally. We review and synthesize current understanding of MHW impacts at the individual, population ...
