Heatwaves in the ocean – ETH Zurich blogpost

Heatwaves are occurring not only on the land but also in the sea, notably “The Blob” in Northeast Pacific and a shorter heatwave on Australia’s west coast in 2010 and 2011. Nereus Alumnus Thomas Frölicher outlines what he calls these “two exceptional heatwaves in the ocean” in his post “Heatwaves in the ocean – a risk to ecosystems?” on the Zukunftsblog – Facts and Views on Sustainability. He discusses the impact these heatwaves have on marine species and ecosystems.

“As the world‘s oceans continue to warm, marine heatwaves are likely to become more frequent and intense,” writes Frölicher. “Observations and model simulations also demonstrate that other factors such as ocean acidification and deoxygenation are putting additional stress on marine organisms and ecosystems.”
