I suspect you mean the gravitational acceleration constant which is about 9.81 m/s^2. This value is actually only valid at Earth's surface (and it also varies from place to place). So in general the answer to your question is no. It might, but it won't be in general.
The value is calculated by using Newton's Law of gravitation: F = G m1*m2 / r^2. Where F is the gravitational force, m1 is the mass of the Earth and m2 is the mass of an object. r is the distance from the object to the center of the Earth. Because r does not differ much, G is just a constant (called Newton's Gravitational Constant), and m1 also does not change much, we usually do the following:
If we are interested in the acceleration an object experiences due to gravity we can use Newton's Second Law: F = m * a.
If we take m as the mass of our object, and a its acceleration due to the gravitational force we must have:
G m1 * m / r^2 = m * a
If we cross out the m (or m2) on both sides we end up with:
a = G m1 / r^2
This a is usually called g. It does not vary much in everyday life, but it does ultimately, so g varies with height.
Yes there is.
But the amount of upward buoyant force from the water cannot overcome the density of the object (which is obviously more dense than water, or the object wouldn't be at the bottom of the ocean.)
Yes, you only float because of the buoyancy force, which counteracts gravity . Gravity is a result of the mass of an object.
The greater the pressure against the bottom of a submerged object produces an upward buoyant force
There is the downward force of gravity, pushing you towards the bottom of the body of water. The second force is buoyant force which keeps you afloat. Since you aren't sinking then the buoyant force is greater than the force of gravity.
buoyant force is always or equal to the force exerted by gravity. that's why an object floats.

As long as any part of the object ... doesn't matter how much ... is below the surface of the water ... doesn't matter how far ... there is buoyant force on it.

An iceberg floating in the ocean is affected by the water pressure and buoyant force on the basis of the Archimedes' principle. This dictates that a volume of a liquid must supported by the pressure of a surrounding liquid.Ê
A large cruise ship.
The buoyant force on an object submerged in a fluid is caused by the pressure difference between the top and bottom of the object. To overcome the gravitational force, the buoyant force acts in the upward direction. The larger pressure at greater depth pushes upward on the object.
The force is the same as long as the volume submersed is the same
