Study Identifies Deepwater Horizon Debris as Likely Source of Gulf of Mexico Oil Sheens

A chemical analysis of oil sheens found floating recently at the ocean’s surface near the site of the Deepwater Horizon disaster indicates that the source is pockets of oil trapped within the wreckage of the sunken rig. Both the Macondo well and natural oil seeps common to the Gulf of Mexico were confidently ruled out.

Researchers from Woods Hole Oceanographic Institution (WHOI) and the University of California, Santa Barbara (UCSB) used a recently-patented method to fingerprint the chemical makeup of the sheens and to estimate the location of the source based on the extent to which gasoline-like compounds evaporated from the oil sheens. The study was published online in Environmental Science & Technology. (more…)

Battling Tuberculosis through Microsoft Technology

Microsoft Research develops biometric monitoring system to help patients complete tuberculosis treatment programs.

BANGALORE, India — Dec. 3, 2012 — Giri Prasad, a 33-year-old tailor who lives in Delhi, first noticed the pain below his ribs. He went to see a doctor, but when it didn’t subside, he traveled to the hospital where he eventually learned he had tuberculosis.

“There were many problems because first and foremost, I am the bread earner for the family,” he says. “If the bread earner falls ill, it is a real problem for those who are dependent on him. Here in the city the biggest problem is that if one falls sick, there is no other person who will come help.” (more…)

Sandy’s Underwater Sandscapes

UD researchers studying ‘fingerprint’ left on seafloor by Hurricane Sandy

Beneath the 20-foot waves that crested off Delaware’s coast during Hurricane Sandy, thrashing waters reshaped the floor of the ocean, churning up fine sand and digging deep ripples into the seabed. Fish, crustaceans and other marine life were blasted with sand as the storm sculpted new surfaces underwater.

UD scientists cued up their instruments to document the offshore conditions before, during and after Sandy’s arrival to scrutinize the differences and better predict the environmental impact of future storms. (more…)
