No ocean crosses the Pacific Ocean. The Pacific Ocean and the Indian Ocean meet each other, but don't cross each other. Like all oceans, around its edges there are many seas, but they don't cross the Pacific Ocean.
A rip current forms when water breaks through the sandbar and begins to flow back down the sloping ocean bottom. (as a sandbar is growing it can trap water flowing along the shore)
A protected area inland of a sandbar is known as a lagoon. Lagoons are shallow bodies of water separated from a larger body of water, like an ocean, by a sandbar or barrier island. They provide habitat for various species of plants and animals and are often used for recreational activities.

A sandbar is a firm ridge of sand that appears off the main shoreline due to ocean wave weathering. Sandbars are typically underwater and can shift in size and shape with changing tides and wave conditions. They can also be important habitats for marine life.
