On earthquake prediction, we’re asking the wrong question!

NonSolidGround | 26 August, 2016
The recent devastating earthquake in Central Italy. The terrible scenes from Ecuador earlier this year. Nepal last year. And all throughout history.  When earthquakes strike, buildings collapse, and tragically people die, lose their homes, jobs, livelihoods. Their streets will never be the same again.

Traveling the length of the Atlantic Ocean, Part 1: Chile to Ihla Terceira, Azores

Notes from the field | 25 August, 2016
The ATom mission is the first to traverse the whole lengths of the Atlantic and Pacific Oceans while making atmospheric measurements from the ocean surface to high altitudes. When we planned ATom, one idea was to compare pollution impacts between the oceans. I expected that human activities would have much greater influence in the Atlantic, because it is smaller than the Pacific and it receives industrial emissions from both sides - the U.S. on the west and Europe to the east. The big emissions from Asia appear to go north to the Arctic, mostly bypassing the Pacific.

HiRISE: Expanded craters in northern lowlands

Red Planet Report | 25 August, 2016
This image shows many small craters over a larger degraded one in the northern lowlands. These small craters are smoother and shallower than their counterparts closer to the equator. Scientists believe this difference is a result of impact into a ......

What can we learn from Earth's magnetic field?

JOIDES Resolution Blogs | 25 August, 2016
While we're casing and preparing to core Hole G at Site U1480, as Agnes wrote about in her recent post, the scientists are mostly working on their reports and discussing their initial interpretations. We have a bit of down time, and we wanted to make use of the great movie lounge downstairs. We watched the geo-fiction movie, The Core.

Women in Geoscience events this fall

Maitri's Vatul Blog | 25 August, 2016
So, women in geoscience. What are we all about? What are some of our barriers to progress? How do these issues affect those working in academia vs. industry? What can we solve now and what may take time? If you want to know more, especially about the Society of Exploration Geophysicists Women's Network, listen to the first-ever Seismic Soundoff podcast. This episode, cleverly titled Women In Geophysics is hosted by SEG's Andrew Geary and me, and features conversations with Klaas Koster, former SEG president who helped launch the SEG women's network and all-around cool dude, and Sally Zinke, the first female president of the SEG and fellow Wisconsin graduate.
