An article about ocean warming temperatures uses numbers in several different ways.
Numbers are first introduced in the seconding paragraph, indicating how much ocean temperatures have risen (1.1 degrees) since the HMS Challenger readings. It is pretty straightforward and uncomplicated.
The second and third (and quite similarly mentioned) numbers take place in the following third and fourth paragraph, where it describes in slightly more detail about the rising ocean temperatures. "The upper parts of the ocean, to a depth of 2,300 feet, warmed by .59 degrees, while the warming was less pronounced (.22 degrees) at depths of 2,950 feet." Again, this is quite direct and evidently without pre-mediated calculations. It's just hard facts.
