The zone, which at about 5,000 square miles (13,000 sq km) is the second largest in the world but still smaller than in previous years, is so named because it contains no oxygen, or too little, at the Gulf floor to support bottom - dwelling fish and shrimp.

By measuring the size of the largest raindrop imprints (inset) in ash that solidified soon after an eruption 2.7 billion years ago (pocked slab, main image) and comparing them to the imprints made by drops of various sizes and momentums in lab tests, the team estimates that the density of Earth's oxygen - free atmosphere 2.7 billion years ago most likely ranged between 50 % and 108 % of today's air and was certainly less than twice its modern density — a thickness insufficient to offset the dimness of the sun at the time.

These tiny clusters would add oxygen atoms more efficiently than larger clusters.

The amount of oxygen in a galaxy is determined primarily by three factors: how much oxygen comes from large stars that end their lives violently in supernova explosions — a ubiquitous phenomenon in the early Universe, when the rate of stellar births was dramatically higher than the rate in the Universe today; how much of that oxygen gets ejected from the galaxy by so - called «super winds,» which propel oxygen and other interstellar gases out of galaxies at hundreds of thousands of miles per hour; and how much pristine gas enters the galaxy from the intergalactic medium, which doesn't contain much oxygen.

Since almost all body tissues consume oxygen, although some tissues more than others (i.e. muscle consumes more oxygen than fat), a person with a larger total body mass will be much more likely to consume more total oxygen than a person with a lower total body mass.

Since muscle consumes more oxygen than fat, a more muscular person would be expected to have a larger VO2max, all else being equal, even when it is measured on a per unit mass basis.
