Why do brinicles sink?

A brinicle is formed when this sea ice cracks and leaks out the saline water to the open oceans. As the brine is heavier than the water around it, it sinks to the ocean floor while freezing the relatively fresh water it comes into contact with. This process lets the brinicle grow downward.
