NASA mission completes eleven years of polar surveys

From 2009 through 2019, NASA’s Operation IceBridge flew above the Arctic, Antarctic and Alaska, gathering data on the height, depth, thickness, flow and change of sea ice, glaciers and ice sheets. Full story ›

Making sea-level science more usable

Adapting to rising seas will require a broader understanding of coastal systems, and of human responses to sea-level rise, a new study says. Full story ›

Seal takes ocean heat transport data to new depths

An elephant seal helps scientists understand how the ocean transports heat between its upper and lower layers — important for estimating how much heat the ocean can absorb. Full story ›
