On July 15 2010, after several failed attempts, the oil gusher was finally capped.

This process is more comparable to tightly wrapped food left too long in a freezer.

Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.

This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.

For 87 agonising days, millions of gallons oil spewed from the ocean floor 5,000 ft beneath the ocean surface, much of it flowing under the relentless gaze of a televised “spill cam” as BP tried various methods to cap the blow-out.

The withering public criticism of BP deepened as birds, fish and shrimp died and thick brown oil washed ashore on the white sand beaches and in the ecologically vital marshlands of the Gulf coast, forcing fishing and tourism businesses to shutter.
