Brine pools are large areas of brine on the ocean basin. These pools are bodies of water that have a salinity three to five times greater than the surrounding ocean. Brine pools are sometimes called seafloor “lakes” because the dense brine does not easily mix with overlying seawater. The high salinity raises the density of the brine, which creates a distinct surface and shoreline for the pool. When submarines dive into brine pools, they float on the brine surface due to its high density. The motion of a submarine can create waves across the brine-seawater interface that wash over the surrounding “shoreline.”
