The data visualisation, released this week, shows Earth's fluctuations as seen from space.
Nasa oceanographer Jeremy Werdell, who took part in the project, says it's like watching Earth breathe. He says the visualisation shows spring coming earlier and autumn lasting longer in the Northern Hemisphere. Also noticeable to him is the Arctic receding over time and, though less obvious, the Antarctic, too.
Researchers compiled the visualisation from satellite imagery.
