Factors Controlling Barrier Island Geomorphology: Insights from Geophysical Surveys

20 March 202410:00 AM (CDT) Barrier islands serve as crucial buffers for coastal communities, mitigating the impacts of storms, hurricanes, and sea-level rise. The geomorphology of these islands significantly influences storm effects and recovery processes, which, in turn, are shaped by subsurface geological and hydrogeological factors. This study examines the interplay between subsurface conditions, island geomorphology, and human development on Padre Island in Texas. Our investigation utilizes frequency-domain electromagnetic (FDEM) and time-domain electromagnetic (TDEM) surveys

A Path to a Career in Hydrogeophysics

17 April 20248:00 AM (CST) This webinar series is aimed to give career perspectives from a variety of geophysicists who have experience in hydrogeophysics, and in most cases, other areas of geophysics as well. The webinar series is intended for students, emerging professionals, and anyone interested in geophysics.  These webinars should be enjoyable for all levels of geophysical expertise and are supported by the SEG Europe Regional Advisory Committee (Europe RAC) and the SEG Near

Geophysical Inversions with SimPEG: An Example with Airborne Electromagnetic Data

14 February 202411:00 AM (CST) Geophysical inversions are used to build models of the subsurface from data collected over the Earth. SimPEG, an open-source Python package, provides a versatile framework for simulating and inverting a variety of geophysical methods, including: gravity, magnetics, resistivity, induced polarization, magnetotellurics, and controlled source frequency and time domain electromagnetic data. In this tutorial, we delve into SimPEG’s comprehensive framework for setting up and running inversions, covering key components such as

What Can Induced Polarization Contribute to Drinking Water Exploration in Deep Aquifers?

21 February 202410:00 AM (CST) Presently, over one-third of the global population, totaling more than 2.3 billion people, face water stress. Since 2000, the impact of global changes has led to severe and prolonged droughts, resulting in approximately 160 million children experiencing water shortages, with episodes lasting 29% longer. Climate change and reduced precipitation exert significant pressure on groundwater recharge, leading to declining water levels in both alluvial and crystalline basement aquifers. This phenomenon results
