What is the boiling point of the Atlantic or Pacific Ocean?

The more salt in the water the higher its boiling point. Ocean water would boil at a temperature above 100 oC. 212 oF but its exact boiling point could be between 115 oC to 120 oC. It depends on the amount of salt. :) :)

That huge long answer has all kinds of true information while never getting to the point of answering your question. Both oceans are salt water of about the same content so the water's boiling point is above 100C. this page http://en.wikipedia.org/wiki/Seawater tells us the salt content in different ways and discusses freezing while not mentioning boiling because the oceans will never boil.
including 35 g/kg salt/water
This page http://wiki.answers.com/Q/What_is_the_boiling_poin... says the boiling point will be raised about 0.5C for each 30 gram/kilogram of salt/water
Therefore the boiling point of ocean water is about 100.58C

Because it contains salt (and not just the salt you see on your table but also other salts like KCl, LiI SrBr etc.), the boiling point of the ocean must be greater than the standard boiling point of water which is, 373 K.Source(s): Chemistry for the Health Sciences (copyrighted)

i see 2 ways to interpret your question.
first are you asking what temperature is needed to start boiling a pot of ocean water in your kitchen. it would start to boil at 213 F or one degree hotter than required for pure water.
the other question might be how hot would you need to get the ocean to boil off all the water. that number starts at 213 F but then the salinity would increase. to reach the state of saturated brine would require an ultimate temperature of 226 F

the deeper you go, the higher the boiling point rises. The reason lies in the increase in pressure. At sea level, the pressure equals one atmosphere. But for every 10 meters you dive, the pressure increases by one atmosphere. So if you were to dive to ten meters, the pressure would equal two atmospheres. A hydrothermal vent 2,500 meters deep experiences 250 atmospheres.
How does this affect the boiling point? As the pressure increases, so does the boiling point. The boiling point of water may be 100 degrees at sea level, but it is much greater deep in the ocean.
For saltwater, the boiling point is raised, and the melting point is lowered. By how much depends on how much salt there is. I'll assume the salt is sodium chloride, NaCl (table salt). The melting point is lowered by 1.85 degrees Celsius if 29.2 grams of salt are dissolved in each Kg of water (called a "0.5 molal solution" of salt. The Na and Cl dissociate right away when dissolved, and so for a 0.5 molal solution of salt, there is a 1.0 molal concentration of ions). The boiling point is raised by 0.5 degrees Celsius for water with 29.2 grams of salt dissolved in each kg of water.

This is based on the equilibrium relationship between boiling point and pressure, where reduced pressure (vacuum) causes boiling of water at lower temperatures than normally encountered at sea level.

It is still water so 100°C, +/- a few cause of the sodium it contains, and deeper down the pressure makes it boil at a higher temperature :)
