What are you cleaning out of the ocean? A sieve will get large particles, but will not get small particles or anything that is dissolved in the water. Some oil that is clumped might be picked up, but would make a mess. The oil that isn't clumped would just run through.
And, you would pose a risk to plant and animal life, large and small. The ocean is full of "life" of all kinds.
the use of a sieve is to get rid of lumps =D
You could use a fine sieve or perhaps a coffee filter, depending on your task.
A filter? Maybe a magnet (if its metal)
You could use a sieve or strainer to separate the rice from the dried soup mix. Just pour the mixture into the sieve and shake it gently to separate the two components.

To separate flour and marbles, you can use a sieve or a mesh strainer. Pour the mixture into the sieve, allowing the flour to fall through while the larger marbles remain on top. Alternatively, you could use a magnet if the marbles are metallic, or simply pick them out by hand if the quantities are small.
The best way to sift sand is to use a fine mesh sieve or screen, which allows smaller particles to pass through while retaining larger debris. You can either shake the sieve gently or use a circular motion to encourage the sand to flow through. For larger quantities, consider using a mechanical sifter or a homemade contraption with a screen attached to a frame for efficiency. Always ensure the sieve is clean to avoid contamination of the sand.
You can use Human hair to help clean up Oil Spills
You can use a sieve to find all the primes numbers between 2 and any given number n.
Suppose you have a solution with particles floating in it. You can use a test sieve to measure the size of the particles. The shaker mentioned in the question shakes the sieve in the controlled way so the particles can be measured accurately.
