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.

2018 University of Maryland Geology Colloquium Series Friday, September 21st 2018 at 3:00 pm in PLS 1130, UMD College Park Dalia Kirschbaum NASA Goddard Finding the Slippery Slope: “Detecting” Landslides from Space Rainfall-triggered landslides occur in nearly every country around the world, causing billions of dollars of damages and cause thousands of fatalities each year. Understanding and modeling the dynamics of rainfall-triggered landslides is a challenging task due to rainfall variability and the complexity of approximating landslide failure mechanisms over broader scales. Satellite data provides a unique perspective to estimate where and when landslides may be occurring as well as to map areas when these events occur. However, the accuracy is highly dependent on the spatial scale and methods used. This presentation outlines several on-going efforts to better understand landslide activity at different spatial and temporal scales using different modeling, mapping and citizen...

Dr. Lorena Medina Luna When I was first asked to write this blog post, I had to think long and hard about what I would say. For me, this comes at an opportune time. For the past three years, I’ve been out of the academic setting and involved in science Education and Outreach (E&O). For the past year, I’ve been working at the National Center for Atmospheric Research as an E&O specialist creating videos on field campaigns, teaching college-level interns how to write and talk about their science, and organizing a science lecture series. Prior to that, I was a bilingual educator-performer at the Denver Museum of Nature and Science. It wasn’t until I got out of academia that I realized that I am one of the few Hispanic/Latinas who have a Ph.D. in the geosciences, specifically in geophysics. My transition into E&O was inspired by my desire to encourage others to believe that everyone has the opportunity to attain higher education, provided they have the support to continue. This...

The NASA/ESA Hubble Space Telescope has started a new mission to shed light on the evolution of the earliest galaxies in the Universe. The BUFFALO survey will observe six massive galaxy clusters and their surroundings. The first observations show the galaxy cluster Abell 370 and a host of magnified, gravitationally lensed galaxies around it.

GSW meeting 1533: Wednesday, October 3 ~ The 2018 Bradley lecture ~ Jane Willenbring Scripps Institution of Oceanography “Not Feeling the Buzz: Tectonics – Not Climate – Limits Heights of Mountains” The potential to rapidly denude topography at and above the glacier Equilibrium Line Altitude (ELA), irrespective of uplift rates, rock type or pre-existing topography, is explored in the glacial buzzsaw hypothesis. In this talk, I offer evidence from cosmogenic nuclide data and numerical models that (1) topography can persist in a state of transience for millions of years through feedbacks that can promote and maintain subdued topography dissected by valleys and that (2) the glacial buzzsaw cuts down–not across. Finally, we compiled tectonic, topographic, and erosion rate data from Arc-Continent convergent margins where the convergence rate is known (Andes, Central America, Cascadia, British Columbia, Alaska, Taiwan, and Makran). Erosion rates and elevation maxima...

The Paleontological Society of Washington 7:00 pm, Wednesday, September 19 National Museum of Natural History, Constitution Ave. entrance Amphibians, lizards, and snakes from the Age of Dinosaurs and the end-Cretaceous mass extinction David G. DeMar, Jr. Postdoctoral Research fellow, Paleobiology Dept., Smithsonian Institution. The Cretaceous-Paleogene (K-Pg) mass extinction, which famously led to the demise of the non-avian dinosaurs, redirected the evolutionary trajectory of life on Earth. Here, I present on how salamanders, lizards, and snakes, a largely overlooked aspect of the vertebrate faunas from this critical time interval, fared during that extinction event. Moreover, these ecologically sensitive taxa or the proverbial ‘canaries in a coal mine’ serve as a litmus test for testing the climate-driven hypotheses of the K-Pg mass extinction. Non-Smithsonian visitors will be escorted from the Constitution Ave. entrance of the NMNH to the Q?rius theatre at 6:50 and 6:55 p.m....
