Scientists tracking a massive iceberg that broke free from Antarctica's Larsen C Ice Shelf last year say dense ice cover has so far prevented it from drifting far out to sea.
An animation showing its movement over the last few months reveals how the trillion-plus ton Iceberg A-68 has shifted as it's battered by ocean currents, tides, and winds in the Weddell Sea.
While the huge chunk of ice,
estimated to be about the size of Delaware, has moved around some, the experts say its surroundings have kept it somewhat locked into place.
Iceberg A-68 is the sixth largest iceberg on record since scientists began keeping track, and its separation from the ice shelf sparked fears about its future impacts on global sea levels.
Despite all the activity in the Weddell Sea, 'its northern end has repeatedly been grounded in shallower water near Bawden Ice Rise,' according to
Project Midas researchers, who have been monitoring the iceberg over the last year.
Comment: At the time A-68 broke off from the Larsen ice shelf global warmists were decrying this as proof of warming, and yet there is so
much sea ice that the ice berg hasn't moved very much. It's been a similar story with
recent polar expeditions where sea ice was so dense that scientists, many convinced that soon 'children won't know what snow is', were unable to get to their destination. The question remains: Because we are seeing
widespread cooling on our planet - at least above ground - what caused the ice shelf to break off in the first place? The cause could lie below, in the form of volcanic activity:
And we can find other clues in the uptick in fissures we're seeing elsewhere on the planet:

The question remains: Because we are seeing widespread cooling on our planet - at least above ground - what caused the ice shelf to break off in the first place? The cause could lie below, in the form of volcanic activity:
- Evidence of volcanic eruptions under Antarctic Ice
- Global warming... in the deeps: Tremendous geothermal heat source is melting Antarctic ice sheet from below
- Antarctica is even colder than scientists thought
