Characteristics
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 the high density. The motion of a submarine can create waves across the brine-seawater interface that wash over the surrounding "shoreline."
