A brinicle (brine icicle, also known as an ice stalactite) is a downward-growing hollow tube of ice enclosing a plume of descending brine that is formed beneath developing sea ice. As seawater freezes in the polar ocean, salt brine concentrates are expelled from the sea ice, creating a downward flow of dense, extremely cold, saline water , with ...

Jun 5, 2017 · We’re used to seeing icicles form on tree branches and the eaves of buildings, but they can also form deep beneath the ocean, creating what’s known as a brine icicle, or brinicle.

Nov 9, 2023 · Basically, a brinicle — sometimes also called an ice stalactite — is a descending tube that projects downward from floating sea ice on the surface of the ocean.

A brinicle is a finger-like formation that grows underneath sea ice. The formation process of this ‘ice finger of death’ has been captured for the first time on camera. Although already known since the 1960s, brinicles are rarely observed in real time.

Apr 26, 2013 · New research reveals how brinicles, long icicles in that descend from ice in the ocean, are formed and how the salt-rich water trapped in ice sheets could've been a ripe place for life to evolve.

Nov 20, 2015 · Creeping through the ocean's depths like a frozen eel, an eerie phenomenon known as the "brinicle" freezes everything it touches. This is what happens when super-saline saltwater enters seawater...

A brinicle is a column of ice that forms in seawater. [1] The name is a combination of the words "brine", which means saltwater, and "icicle". [2] A brinicle starts forming from the top of the water down. [3] A brinicle freezes everything in its way as it forms. [3] It can reach the bottom of the ocean, where it can also form ice on the seabed. [4]

Apr 9, 2013 · Extraordinary tubes of ice that grow down into the ocean from ice sheets could be as significant for the origin of life as hydrothermal vents, say chemists. One of the more curious processes that...

When these ice crystals form a tube around a descending column of brine, a brinicle is formed. The word brinicle is a contraction of “brine icicle.” They are also called “sea stalactites” due to their resemblance to this common cave structure. Brinicles, however, are not hard like rock.

A brinicle can capture slow-moving sea creatures within it, freezing them into the brinicle and the sea bed. Once it hits the ocean floor, the brinicle spreads into an icy web, leaving a trail-like bed of ice across the sand. The phenomenon was only first discovered in the 1960s, with an explanation proposed in 1971.
