Every year, upwelling brings cold, nutrient-rich waters from the ocean's depths to the surface, replacing the warmer, nutrient-depleted water. This typically occurs during January to April, when the ...

Tropical upwelling zones are often overshadowed by their higher-latitude counterparts in ocean science, yet they play an outsized role in maintaining global marine productivity. These systems help ...

Mantle plumes beneath volcanic hotspots, like Hawaii, Iceland, and the Galapagos, seem to be anchored into a large structure within the core-mantle boundary (CMB). A new study, published in Science ...
