Post-Sandy Sewage

13.11.2012
With millions of gallons of raw sewage dumping into New Jersey waterways following Hurricane Sandy, University of Delaware scientists are using satellites to help predict the sludge’s track into the ocean.

“Technically, you can’t identify raw sewage from a satellite, but you can find river discharge that you suspect has raw sewage,” said Matthew Oliver, assistant professor of oceanography in the College of Earth, Ocean, and Environment. “The reason why is because river discharge usually has a very different temperature and color than the surrounding waters.”

Oliver and his students have previously examined the ability of satellites to detect coastal plumes.

Oliver participates in the Mid-Atlantic Regional Association Coastal Ocean Observing System (MARACOOS), which has been carefully following Hurricane Sandy and its after effects. Headquartered at UD, the organization aggregates ocean data collected along the Atlantic coast from Massachusetts to North Carolina to share with researchers, government officials and the public.

As the storm headed up the coast, the New Jersey Department of Environmental Protection (NJDEP) contacted MARACOOS for information. Xiao-Hai Yan, Mary A. S. Lighthipe Professor of Oceanography and director of the Center for Remote Sensing, worked to install the satellite dish at UD to provide real-time coverage of regional disaster events.

“We at UD provide satellite support for MARACOOS,” Yan said. “So that is why we have our images focused on that area right now.”

According to NJDEP, Hurricane Sandy damage took several wastewater treatment facilities offline, causing untreated sewage into certain waterways. Recreational boaters, anglers and crabbers were advised on Friday, Nov. 2, to avoid those waterways and not eat any fish, crustaceans or shellfish from these waters due to contamination from bacteria and viruses. Additional advisories were issued on Nov. 5 and Nov. 6.

Affected waterways are located in northern New Jersey and include the Hudson River, Passaic River, Hackensack River, Newark Bay, Kill Van Kull and Arthur Kill, Raritan Bay, Raritan River, Sandy Hook Bay and northern Barnegat Bay.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
