The amount of salt.
The density of ocean water is calculated using the temperature, salinity, and pressure of the water. These factors impact the water's mass and volume, which determines its density. The density of ocean water can vary depending on these factors, with colder, saltier, and deeper water typically being denser.

Density is important in the water column because it determines the vertical movement of water masses. Water with higher density sinks below water with lower density, driving ocean currents and influencing the distribution of nutrients and heat in the ocean. Changes in density due to temperature and salinity variations also affect marine ecosystems and climate patterns.
The density of ocean water is influenced by both salinity and temperature. Higher salt concentrations increase density, as dissolved salts add mass without significantly increasing volume. Conversely, warmer water is less dense than cooler water, as it expands. Therefore, the interplay between salinity and temperature determines the overall density of ocean water, which affects ocean circulation and marine ecosystems.
the density= mass/volume, so as you can see the mass of one cubic meter of water determines the density of the water.
gravity determines waters position
The size of an object has little to do with whether it will float. Size relative to weight, or density, is what determines bouyancy. If the object weighs less than the amount of water it can displace, it floats.
The density of the solid.
The water would have the same density anywhere it is.
The density of an object compared to the density of water determines whether it will float or sink. If the object is less dense than water, it will float. If it is more dense, it will sink.
It is called an ocean current
Density is the characteristic property of the material and it does not depend on the liquid in which it is immersed
