“Fuel oils, are arguably the most challenging petroleum products to analyze and investigate following marine-based spills,” said Reddy. Although low, the levels of PAHs might accumulate in certain parts of the marine environment. These substances were present in minute amounts, but still detectable thanks to the technology available in the collaborating laboratories. WHOI’s pioneering discoveries stem from an ideal combination of science and engineering—one that has made it one of the most trusted and technically advanced leaders in basic and applied ocean research and exploration anywhere. We play a leading role in ocean observation, and operate the most extensive suite of data-gathering platforms in the world.
