A new method of measuring the interaction of surface water and groundwater along the length of the Mississippi River network adds fresh evidence that the network’s natural ability to chemically filter out nitrates is being overwhelmed.
Atlantic croaker living in the large Gulf of Mexico "Dead Zone" exhibit severe reproductive impairment with potential long-term impacts on the fish's population abundance, researchers from The University of Texas at Austin's Marine Science Institute have found.
Researchers at The University of Texas at Austin and colleagues will use a three-year, $1.5 million grant from NASA to develop computer models to study how changes in climate and land use affect watersheds and coastal ecosystems, seeking to improve understanding of the Texas coast, including dead zones that form in the Gulf of Mexico.
Marine scientist Zhanfei Liu is studying the effects of the Deepwater Horizon oil spill on oxygen levels in the northern Gulf of Mexico in part through a recently received National Science Foundation grant for Rapid Response Research (RAPID).
Whether a large area of low oxygen water called the "dead zone" in the northern Gulf of Mexico could cause declines in environmentally and economically important fish populations is the subject of a new study by University of Texas at Austin marine scientist Peter Thomas.
