Geotimes

Geotimes is a free electronic newsfeed for the geoscience community. The American Geosciences Institute coordinates and edits Geotimes, but it is the result of contributed materials from societies, geoscience organizations and others in the community. Do you have a geoscience blog or newsfeed with an RSS feed? It may be a good fit for Geotimes. To learn more about RSS or to submit information to Geotimes by email, please contact Joe Lilek at geotimes@americangeosciences.org. Events can also be listed on the AGI Geoscience Calendar.

Bring ONE STRANGE ROCK to your School for Free: From award-winning filmmaker Darren Aronofsky, National Geographic’s new docu-series ONE STRANGE ROCK is a mind-bending, thrilling journey that explored the fragility and wonder of planet Earth–one of the most peculiar, unique places in the universe. This earth science series is narrated by actor Will Smith and features perspectives from eight astronauts on the wonders of Earth as seen from space. The series debuts tonight, March 26, at 10pm eastern time.   National Geographic’s ONE STRANGE ROCK Educator Resources are now available, including a curriculum guide with resources to help extend the themes and topics from ONE STRANGE ROCK into meaningful discussions. These resources also include activity ideas to conduct with student groups, as well as an interactive quiz to assess learning. Click here for the series' curriculum.   National Geographic is making the first episode available for free screenings this spring in high...

There's a Jupyter Notebook for you to follow along with this tutorial. You can run it right here in your browser. We often use Ricker wavelets to model seismic, for example when making a synthetic seismogram with which to help tie a well. One simple way to guesstimate the peak or central frequency of the wavelet that will model a particlar seismic section is to count the peaks per unit time in the seismic. But this tends to overestimate the actual frequency because the maximum frequency of a Ricker wavelet is more than the peak frequency. The question is, how much more? To investigate, let's make a Ricker wavelet and see what it looks like in the time and frequency domains. >>> T, dt, f = 0.256, 0.001, 25 >>> import bruges >>> w, t = bruges.filters.ricker(T, dt, f, return_t=True) >>> import scipy.signal >>> f_W, W = scipy.signal.welch(w, fs=1/dt, nperseg=256...

AGI was saddened to learn of the passing of Walter L. Youngquist, a longtime supporter of the Institute. An accomplished geoscientist, Youngquist was a Fellow of the Geological Society of America and the American Association for the Advancement of Science, as well as an Emeritus member of the American Association of Petroleum Geologists. He died on February 20, 2018, of age-related causes. He was 96 years old.

By Robin Bell, Eric Davidson, and Chris McEntee  Roughly six months ago, AGU leadership adopted a revised ethics policy that took a noticeably stronger stance on workplace climate issues by including harassment, bullying, and discrimination in the definition of scientific misconduct. In doing so, we recognize appropriate personal conduct as part of the broader context of scientific responsibility and the expected research behavior—because harassment, bullying, and discrimination negatively impact the scientific enterprise. The policy, as we outlined in an earlier From the Prow post, was the culmination of months of work by the Ethics Task Force, initially convened by then President Margaret Leinen, to review AGU’s previous policy and make recommendations, and many discussions with AGU members and among Board and Council. However, the policy is just one step that AGU has undertaken in efforts to create a safe, inclusive community for Earth and space science. To maintain focus and...
