Sorry, the atmospheric pressure has really nothing to do with the speed of sound at 0c, but he temperature is very important Scroll down to related links and read the short article "Speed of sound - temperature matters, not air pressure". The air pressure and the air density are proportional to each other at the same temperature.
You can't... Pressure is influenced by many other factors, temperature and density for example... Also the height is a factor (atmospheric pressure)
Any factor which alters the density of the sea water causes a variation in the velocity of sound in seawater. Basically, changes in temperature and salinity will result in changes in density. This can cause large changes in velocity. For example, seawater in the carribean with a temperature of 20C and a salinity of 37ppt might result in a velocity of, say, 1530m/s, whereas seawater in the north sea with a temperature of 3C and a salinity of, say, 31ppt, would result in a velocity of, say, 1480m/s.
Temperature, concentration, sometimes also internal fluid velocity. Moreover density, type of liquid, surface where it flows, viscous drag.
Both pressure and volume of any gas are directly, linearely proportional to temperature in Kelvin, that is degree Celsius + 273.13. Density is not directly related to temperature, it is related to mass and volume.
Density = mass divided by volume. Mass is determined by the individual atoms or molecules and their compression (how close together they are). Compression is affected by external elements such as temperature and atmosphere. Temperature can increase or decrease density (hotter temps lead to decrease in density as atoms separate). Atmospheric pressure can also change the density (air is less dense the further you get from Earth/higher you go in the sky).

Pressure.
Gravity. Atmospheric pressure is the weight of a column of air. Of course, the temperature of that air changes it's density and therefore it's weight (i.e. pressure)

In weather maps, atmospheric pressure is measured in millibars. Standard atmospheric pressure is 1013.2 millibars at sea level. Air pressure varies depending on temperature and air density.

Temperature - low temperature gains altitude quicker Pressure - High pressure gains altitude quicker Density - Low density gains altitude quicker
No, the absolute pressure in a liquid of constant density would not double in this situation. This is because the atmospheric pressure is an independent variable, so it will keep the absolute pressure from doubling.
Temperature, concentration, sometimes also internal fluid velocity. Moreover density, type of liquid, surface where it flows, viscous drag.
Winds follow air pressure gradients and these are determined by atmospheric density.
Dynamic pressure of air = 0.5 * density * velocity of air = Pascal Where: Density = kg / cubic meter Velocity of air = m / s
Density of a liquid is indirectly proportional to the temperature. When the temperature raises, the density of the liquid decreases. Therefor the temperature has an effect on water density.
