“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.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
