What percentage of an ocean oil spill is recoverable? The amount of oil recovered after an oil spill depends on a number of factors, including the type of oil, the location and the availability of clean- up equipment.


In spills involving lighter, more volatile oils, a larger percentage will evaporate. Spills in enclosed bays or coves tend to be more easily recovered than those in open ocean. And the proximity of clean-up equipment can be critical, because spilled oil will spread out quickly and become difficult to recover.


For open ocean spills, 10 to 20 per cent is considered a good recovery rate by spill specialists. And as much as 70 per cent might be recovered under the best of circumstances, when a spill occurs in a highly enclosed area and the clean- up starts quickly.


Which is the oldest orchestra in the world today? The Gewandhaus Orchestra of Leip zig, Germany, is thought to be the oldest. It is more than 200 years old, and owes much of its early importance to composer Felix Mendelssohn.


In the United States, the Philharmonic-Symphony Society of New York, better known as the New York Philharmonic, is the oldest. The orchestra was founded in 1842.
