Thus, the oxygen withholding capacity and the percentage of oxygen in water decreases. Dolphin numbers are down. Factors such as oil-biodegradation, ocean currents and response measures (dispersants, burning) reduced coastal oiling. Since most of the oil floats in water, the sunlight absorbing capacity of the water decreases. The BP oil slick had spread over 580 square miles in just three days. Oceanic oil spills became a major environmental problem in the 1960s, chiefly as a result of intensified petroleum exploration and production on continental shelves and the use of supertankers capable of transporting more than 500,000 metric tons of oil.
