High-tech mooring will measure beneath Antarctic ice
Gloucester Point VA (SPX) Jan 10, 2017
Earth's oceans have soaked up about a third of the carbon dioxide added to the atmosphere by humans through use of fossil fuels and other activities. That's good news for those concerned with greenhouse warming, but bad news for the marine life that's sensitive to the increasing acidity extra CO2 brings to ocean waters. Dr. Elizabeth Shadwick, an assistant professor at William and Mary's Virginia Institute of Marine Science, has now deployed a high-tech mooring beneath the seasonally ice-covered w ... read more
