Save the…Sharks!?

Save the…Sharks!?

By Dr. Greg Stunz

“We have been hating sharks on general principles for centuries … now it is high time that they should pay up.”  This was a 1928 invitation to harvest sharks in Scientific Monthly (now Science). This mentality has been accepted by generations of fishermen and fishery managers. However, modern science shows many of the world’s shark stocks have decreased to unprecedented levels, placing ocean ecosystems in peril. Through his research and interactions with sharks, Dr. Stunz will share the history and current status of their declines, and their future along the northern Gulf of Mexico.

Hurricane Harvey: Flood Emergency Response

Hurricane Harvey: Flood Emergency Response

By David Maidment, Sarah Labowitz, Melissa Huffman, and Suzanne Pierce

Hurricane Harvey was the most significant severe storm of 3-5 days duration in United States history, raining 50 inches or more in parts of Texas. A new National Water Model can forecast water flow in streams and rivers similar to how the National Weather Service forecasts weather. David Maidment shares his experience applying this model to Texas, including his behind-the-scenes experience working in the State Operations Center during Hurricane Harvey and his recommendations for how Texas can become resilient in the face of future large-scale floods. For the Q&A session, David will be joined by a panel of experts on disaster response.

Co-sponsored by Planet Texas 2050, UT’s first grand challenge research initiative that’s bringing together more than 100 researchers from across campus to find ways to make Texas more resilient in the face of rapid population growth and climate extremes. Additional support provided by the Leon Jones Hot Science - Cool Talks Endowment.
