Why are there lines in the sea?

If the winds blow strong enough, streaks of debris such as seaweed or foam can collect where the vortices converge, producing windrows. On the other side of these adjacent twisting vortices are long lines of divergence or upwelling, where water rises from below the surface. The water remains relatively calm.Click to see full answer. Keeping this in consideration, why are there lines in the ocean?In other words, there are no physical lines on the ocean floor. These lines are artifacts of the ocean floor mapping process. Oceanographers use sonar—sound waves—to map the ocean bottom. The sound travels through the ocean, bounces off the seafloor, then travels back to the ships.Additionally, what does square lines in the ocean mean? Square waves, also known as cross sea or cross waves, are square-shaped grids that form on the surface of the ocean. The waves appear gentle on the surface, but they are strong enough to steer swimmers, surfers, boats, and even large ships into unintended courses. Then, what are the white lines in the sea? The Pacific White Line is a periodic but random natural feature in the Pacific Ocean. It is a huge collection of fish, foam and algae that usually occurs between January and August. When conditions are right it can be seen from space.Why is it called the Sea?The sea was first named by the ancient Greeks who called it “Inhospitable Sea.” The sea got this reputation because it was difficult to navigate, and hostile tribes inhabited its shores. Later, after the successful development of the coast by Greek colonists, the sea was renamed “Hospitable Sea.”
