Shifting currents and melting ice in the Antarctic

Based on data from autonomous sensors floating in the oceans, researchers are able to model the flows and characteristics of ocean currents in more detail than ever before. For The New York Times, Henry Fountain and Jeremy White show how the shifts have unwelled centuries-old water deep in the ocean, which releases carbon into the air. The scrollytelling format of this piece works well to show sensor estimates over time....

Arctic ice melting

One way to gauge the amount of ice in the Arctic is to look at the average age of the ice. From the NASA Scientific Visualization Studio, the map above shows the estimated age of ice on a monthly basis, going back to 1984: One significant change in the Arctic region in recent years has been the rapid decline in perennial sea ice. Perennial sea ice, also known as multi-year...

Mapping ice layers with radar data

I don't know exactly how much data NASA has in the bank, but I think it's a lot. Explained in the video below, they estimated the age of ice layers in Greenland by flying a plane over the Greenland Ice Sheet and pulsing radar to gather information. Tags: ice, NASA, weather
