Scientists know the depth of the ocean by using technology like the Deep Worker or the "Alvin". It takes them to the bottom of the ocean so they can study ocean life. Also ships use sonar (SOund NAvigation and Ranging) to see what the depth of the ocean is.
You would find the Samoan islands in the pacific ocean.
You would expect to find photosynthetic organisms at the greatest depth in the euphotic zone of the ocean. This is because sunlight can penetrate to this depth, providing the necessary energy for photosynthesis. Beyond the euphotic zone, light levels decrease rapidly, making it difficult for photosynthetic organisms to survive and carry out photosynthesis.

convergent boundaries are easy to find most of them are found in the ocean. One Famous convergent plate boundary would be the Sunda Double Trench. It is found in the Indian ocean and it reaches a depth of 24,440 feet. It is the deepest trench in the Indian Ocean.
