The temperature obviously varies considerably from the poles to the equator but the average temperature of the ocean surface waters is about 17 degrees Celsius (62.6 degrees Fahrenheit).
(from related link) 20 degrees Fahrenheit
54 deg. Fahrenheit
59-62.9 f
The oceans will rise, flooding some Coastlines.
like 70 or 60 or 80 some degrees
In all oceans in any temperature.
they aksing for which zone has the highest average they not aksing for all oceans.......
For the global oceans, the August average sea surface temperature was 0.57°C (1.03°F) above the 20th century average of 16.4°C(61.4°F), tying with 1998, 2003, 2005, and 2009 as the record highest for August.
The average temperature is as low as 60F or 80F. the all together average is about 70F.
The average temperature during winter is about 20 degrees Fahrenheit. The average temperature during summer is about 80 degrees. All in all, it's about the same as it is now.
To calculate the average temperature, you add up all the temperatures and then divide by the number of temperatures you added together. This gives you the average temperature.
The temperature of the ocean at the surface is not constant across all oceans. For example, the Arctic Ocean will have a much colder surface temperature than the Pacific.
The word "mean" means average. The mean temperature is the average temperature. To calculate it you add all the temperatures together and divide by the number of temperatures you added.
