Tree Rings on Hawai’i Could Hold New Knowledge About El Niño

Annual tree rings are a rare find in the tropical islands of the eastern Pacific. The new discovery of trees with annual rings on a Hawaiian volcano could provide new climate data from a part of the world where much of the variability of the El Niño-Southern Oscillation originates.

Tracing the Arctic

The land surrounding the Arctic Ocean is like a set of cradling arms, holding the ocean and the sea ice in a circular grasp. Within that cradle is a unique mix of waters, including freshwater from melting glacial ice and large rivers, and a salty mix of relatively warm Atlantic water and the cooler Pacific water.
