How does a brinicle form
WebHow does a brinicle form? As an article in Technology Review explains, brinicles form because when seawater along the ocean surface freezes to form ice, it exudes salt. That increases the salinity of nearby water, which in turn lowers its freezing point, so that it stays liquid even though it’s really, really cold. ... WebJul 31, 2013 · It reveals the never-before-seen formation and deadly aftermath of a brine icicle (or brinicle), which “plunges toward the seabed from the Antarctic ice shelf above, freezing marine invertebrates in its path and killing everything it touches.” That’s the description accompanying the video.

WebA brinicle ( brine icicle, also known as 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, and saline water ...
WebHow are brinicles formed? To start with, we need to understand a very important property of water: the higher the concentration of salt, the lower its overall freezing point. Ordinary tap water freezes at 0°C because it’s relatively pure. Sea water contains salt and therefore freezes at about −2°C.
