Glacial Ice Cores Reveal 15,000 Year Old Microbes
Ancient ice contains a rich microbial record going back thousands of years. Recent advances have provided tools to study their genes and evolution, but climate change threatens to erase this frozen archive.

As the Greenland Ice Sheet Retreats, Mercury is Being Released From the Bedrock Below
Scientists have found that Greenland’s bedrock is rich with mercury in some areas — and as the ice sheet rapidly melts, that mercury is being released into local waters.

Collecting More Than Just Seismic Data Along the Cascadia Fault
While researchers search for a megathrust fault off the Pacific Northwest coast, they are also helping to map the seafloor in high resolution and detect underwater methane seeps.
The first Earth Day in 1970 ignited a movement to stop polluting our planet. Today, our scientists and experts are tackling the most pressing challenges to achieve real-world impact.
