Line 64:
===Highest oxygen concentrations in their maps===
'''''(background information):''''' Saturated sea water is about 9 mg per liter at 20 °C ranging up to 11 mg per liter at 0 °C because cold water takes up the oxygen more readily.<!-- see for instance the two "Dissolved Oxygen" cites in the Background sources-->.
[[File:Halichondria panicea.jpg|thumb|Halichondria panicea or the breadcrumb sponge- Stamenković et al's paper cites research by Mills et al using this sponge which showed it can survive with only 0.002 moles per cubic meter (0.064 mg per liter). This new research suggests that these concentrations can be achieved in {{w|Supercooling|supercooled}} brines on modern Mars in polar regions.]]
The highest oxygen concentrations of all, occur when the water is colder, which is most easily attained in polar regions. That's where they found there would be enough for simple sponges.
