The buoyancy of an object submerged in water does not normally change substantially with depth, but there are caveats to this answer.
The buoyant force is equal to the weight of fluid displaced.
In the case of non-compressible liquids the buoyancy force does not change with depth.
No material is truly incompressible, so if you go really deep (the bottom of the ocean for example), the fluid is compressed a little bit, and so a given volume of the fluid is heavier (denser) and the buoyancy force is greater. (The difference in the density of sea water between the surface and the greatest depth of the ocean is only a few percent.)
Buoyancy forces are also present in compressible gases, for example, a balloon in Earth's atmosphere. In this case, air closer to the Earth's surface is more compressed and thus significantly denser, meaning a fixed volume object will experience a noticeably greater buoyancy force at lower altitudes.
Finally, the buoyant force can change with depth because the volume of the object changes with depth. Certainly this is an important factor with balloons in air and if you submerged a balloon in water the effect of pressure on the volume of the balloon would be a dominant factor on buoyancy. This is present, though small, for solid objects as well.
One more thing, if you are being really picky, gravity changes with depth as well and so affects buoyancy. Obviously not important on Earth, but dropping a mass into a gas planet does have to incorporate the change of gravity with depth and all the other caveats mentioned above.

Are PFD's more buoyant in deep water than in shallow water?
No, the buoyancy of a PFD does not change based on the depth of the water. The buoyancy of a PFD is based on its design and materials, not the depth of the water. It will provide the same level of buoyancy regardless of the water depth.
How does change in buoyancy affect the function of a submarine?
A change in buoyancy affects a submarine's ability to rise and sink in the water. By adjusting the amount of water in its ballast tanks, the submarine can control its buoyancy and depth in the water. This is essential for navigating through different depths and maintaining stability.
Are Personal Floation Divcess more buoyant in deep water?
No the depth of the water does not change buoyancy. Floating in salt water is easier than in freshwater.
Can you change you center of buoyancy?
You can change your center of buoyancy by adding weights to a different area.
How do i know if you have positive or neutral buoyancy?
You can determine your buoyancy by observing whether you float, sink, or stay suspended in water. If you float on the water's surface, you have positive buoyancy. If you sink, you have negative buoyancy. When you remain suspended at a certain depth, your buoyancy is neutral.
How does a change in depth affect buoyancy?
As depth increases, the pressure on an object also increases. This increased pressure compresses air in the object, thus reducing its volume. This reduction in volume causes the object to displace less water, resulting in a decrease in buoyant force.
how to calculate tax buoyancy?
Tax buoyancy is calculated by dividing the percentage change in tax revenue by the percentage change in GDP. The formula is: Tax Buoyancy = (% Change in Tax Revenue) / (% Change in GDP). A tax system with a buoyancy greater than 1 indicates that tax revenue grows faster than the economy, while a buoyancy less than 1 indicates that tax revenue grows slower than the economy.
What is a buoyancy compensator?
A buoyancy compensator, typically worn by scuba divers, is a piece of equipment that helps control the diver's buoyancy underwater. It can be inflated or deflated to adjust buoyancy and maintain a desired depth. It also provides a means for attaching other diving equipment and can serve as a flotation device on the surface.
Two ways to find the volume of a plastic cube?
find buoyancy and the height depth and with and you've got your answer
Is buoyancy a physical or chemical change?
Buoyancy is a physical change, not a chemical change. It results from the relationship between an object's density and the density of the fluid it is placed in, causing the object to either float or sink.
What are the types of buoyancy?
The two main types of buoyancy are positive buoyancy, which causes an object to float, and negative buoyancy, which causes an object to sink. Another type, neutral buoyancy, occurs when an object neither sinks nor floats but remains suspended in water at a specific depth.
Is the bouyant force of water proportional to its depth?
No. Water is incompressible. Buoyancy is determined by density, and being incompressible the density stays the same. Once an object is submerged there's no more buoyancy to be generated.
