The Antarctic Circumpolar Current, or ACC, is the strongest ocean current on our planet. It extends from the sea surface to the bottom of the ocean, and encircles Antarctica.The oceans of the world, however, are not homogeneous. Horizontal variations in temperature and salinity cause the horizontal pressure gradient to vary with depth. This is the baroclinic field of mass, which leads to currents that vary with depth. The horizontal pressure gradient in the ocean is a combination of these two mass fields.The Gulf Stream is a powerful western boundary current in the North Atlantic Ocean that strongly influences the climate of the East Coast of the United States and many Western European countries. Click the image for a larger view. One particularly powerful western boundary current is the Gulf Stream. The Gulf Stream, paired with the eastern ... Most ocean crabs are considered carnivores and eat just about any meat they can find. There are a few species that are omnivores, however, and eat plants as well as meat.Tracking 30 Years of Sea Level Rise.
