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: Vorstoß ins Innere der Atome

Mit Hilfe einer neuen Lasertechnologie haben es Physiker vom Labor für Attosekundenphysik der LMU und des MPQ geschafft, Attosekunden-Lichtblitze mit hoher Intensität und Photonenenergie zu produzieren. Damit konnten sie erstmals die Interaktion mehrere Photonen in einem Attosekundenpuls mit Elektronen aus einer inneren atomaren Schale beobachten konnten.

Wer die ultraschnelle Bewegung von Elektronen in inneren atomaren Schalen beobachten möchte, der benötigt ultrakurze und intensive Lichtblitze bei genügend...

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

Eine Gruppe von Forschern um Andrea Cavalleri am Max-Planck-Institut für Struktur und Dynamik der Materie (MPSD) in Hamburg hat eine Methode demonstriert, die es erlaubt die interatomaren Kräfte eines Festkörpers detailliert auszumessen. Ihr Artikel Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, nun online in Nature veröffentlich, erläutert, wie Terahertz-Laserpulse die Atome eines Festkörpers zu extrem hohen Auslenkungen treiben können.

Die zeitaufgelöste Messung der sehr unkonventionellen atomaren Bewegungen, die einer Anregung mit extrem starken Lichtpulsen folgen, ermöglichte es der...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...
