EOS Knowledge Capsule: Unlocking Climate Secrets 

In this EOS Knowledge Capsule Earth scientist Nathalie Goodkin and her team take us underwater in search for coral colonies that are 300 to 500 years old. The team shows how corals are drilled, extracted, and later analyzed in the lab. The chemical composition of these corals changes throughout time based on the temperature and chemical composition of seawater. These changes can help to understand how the Earth's climate fluctuates over time.

The Knowledge Capsules are created by the EOS Art Group to communicate the excitement and depth of Earth Science to an audience of non-scientists.
