How are Scientists Keeping an Eye on Earth’s Oceans?

The ocean is very important to human wellbeing because it provides us with food, medicines, transportation, recreation, and homes for many marine (ocean) species. To study the ocean, scientists must consistently collect data for many years. One important way to get this information is to go on ships to take measurements. But there are places that are difficult for ships to get to, such as the Arctic and the Antarctic, and seasons that make travel impossible. To collect measurements from Earth’s oceans in all seasons and many more places than ships usually go, scientists invented Argo robots.

Robots monitor the deep sea

GO-BGC's sister program Deep Argo in the spotlight.  In a recent NBC Bay Area news report "Underwater robots tracking climate change", GO-BGC and Argo's Sarah Purkey from Scripps Institute of Oceanography (SIO) talks about Deep Argo robots that track climate change in...

Congrats to Dr. Talley

Dr. Lynne Talley was elected to membership in the National Academy of Sciences in recognition of her distinguished and continuing achievements in original research.

Revolutionizing our understanding of the ocean
