What We Do
People in the Physical Oceanography Numerical Group work on problems in the coastal ocean using numerical simulations. Currently, the Regional Ocean Modeling System (ROMS) is used for all of the simulations.
What's New
October 2017
Kristen Thyng (PONG), Kerri Whilden (GERG), Karen Dreger (GERG), and Veronica Ruiz Xomchuk (PONG) were sampling on Galveston at the begining of October.
September 2017
Rob Hetland, Scott Socolofsky, and Kristen Thyng with Ben Hodges at UT received an NSF RAPID (Hurricane Harvey) for sampling the plume coming out of Galveston Bay to better understand the complex and previously unstudied dynamics when a huge pulse of freshwater enters the bay and then the shelf.
Kristen Thyng and Kerri Whilden (GERG) lead the LEG2 of the NSF RAPID cruise outside Galveston bay at the end of September.
