Podcasts about research geophysicist

Knowing exactly where faults are located is important both for scientific reasons and for assessing how much damage a fault could inflict if it ruptured and caused an earthquake. In the podcast, Rufus Catchings describes how we can use natural and artificial sources of seismic waves to create high-resolution images of fault profiles. He also explains how faults can act as seismic waveguides, an effect that enables us to determine whether faults are connected to each other. In Napa, a famous wine-growing area near San Francisco, he used guided waves to determine that an active fault is actually ten times longer than previously thought. Rufus Catchings is a Research Geophysicist at the US Geological Survey (USGS). Over the past 40 years, he has studied many dozens of faults in California and elsewhere to pin down their precise locations and help assess the risks they pose.

In this episode of Causes or Cures, Dr. Eeks chats with Dr. Tom Parsons about his study called The Weight of New York City, Possible Contributions to Subsidence from Anthropogenic Sources published in Earth's Future. He tells us what subsidence is and how it is measured, how and by how much the skyscrapers and buildings of NYC are contributing to it, why we should care about it, and what are the potential short-term and long-term implications. He talks about the potential implications from a "One Health" perspective, specifically in the realm of how our environment impacts our health. He also talks about what his study shows versus how it was presented by many media outlets, serving as an interesting case study for those in the scientific communications field. Dr. Tom Parsons earned his PhD in geophysics from Stanford University and is a Research Geophysicist at the US Geological Survey in Menlo Park, California.

In this episode, host Andrew Geary speaks with Steve Sloan on smart city geophysics, the featured special section in September's The Leading Edge. Steve highlights the wide array of papers highlighting the tools and techniques used to achieve the best results in less than ideal environments. We discuss the importance of geophysics in urban settings, how geophysics is uniquely suited to work in these environments, and the benefits afforded geophysicists in high-noise surroundings. We also discuss the role of privacy in obtaining data in urban settings. This is a great primer on the near-surface and its value in major population areas.

Getting involved in your professional association is the key to unlocking its power. And volunteering is a great way to get started. At SEG, committees serve this vital role of connecting members to the society, as well as to each other. In this conversation with Andrew Geary, Dr. Sergio Chávez-Pérez, Chair of the Research Committee, discusses what the committee does, how to get involved, and how it has impacted Sergio's career. Sergio also discusses why engaging geophysicists outside Houston, Texas is essential for the future of applied geophysics. Visit https://seg.org/podcast/Post/9063 for Sergio's full bio and the link to read May's The Leading Edge highlighting the Committee.

In 2014 there were 585 magnitude three or above earthquakes in Oklahoma. In 2013 that number was only 109. And it turns out we’re to blame for the increase.On the show this week we talk to Research Geophysicist and Deputy Chief of the USGS Induced Seismicity Project Justin Rubinstein to find out more about induced earthquakes—and why they’re happening in places you might not expect.

Sunlight Absorption on the Greenland ice sheet Experiment (SAGE)" Tuesday, January 07 2014, 12:00pm - 1:30pm 041 Haldeman Center Chris Polashenski, PhD, Research Geophysicist, Cold Regions Research and Engineering Laborator (CRREL) Big changes are happening on the Greenland Ice Sheet. Trends show increasing melt extent, longer melt seasons, lower surface albedo, higher ice temperatures, and increased ice flow. All of these are important because the Greenland Ice Sheet is a major potential contributor to sea level rise. Zoe Courville, PhD, and Chris Polashenski, PhD, at the US Army Cold Regions Research and Engineering Laboratory (CRREL) are leading a series of studies aimed at better understanding how albedo feedbacks are contributing to enhanced melt on the ice sheet. These studies are organized around large scale traverses of the ice sheet, observing albedo, snow properties, light absorbing impurity concentrations, and firn temperatures, and synthesizing data from the traverses with remote sensing observations and large scale modeling. The first traverse occurred from April-June 2013 and preliminary results will be presented. Part of the traverse followed the route pioneered by the godfather of Greenland research, Carl Benson. Replicating Benson's observations shows substantial warming has occurred in mid altitudes of the ice sheet. The traverse also found enhanced black carbon concentrations in the 2012 melt layer. We analyze these to assess the role that black carbon deposition may have played in the 2012 melt event, and compare the impacts of black carbon with grain metamorphosis. Finally we discuss plans for 2014 and invite comments and discussion. Dr. Polashenski is a research geophysicist with the Terrestrial and Cryospheric Sciences Branch at CRREL specializing in the physical properties of sea ice and snow. He received his undergraduate degree and a doctoral degree in material engineering from the Thayer School of Engineering at Dartmouth, and is a veteran of Dartmouth's NSF IGERT program on polar environmental change. Now he leads research programs exploring processes of the cryosphere, particularly those that influence energy balance feedbacks, such as melt pond formation on sea ice, aerosol deposition in snow, and snow grain metamorphosis.
