Last year, the iceberg A-68 broke off Antarctica's Larsen C ice shelf after years of cracks spreading across the ice - but it's remained "stuck" near the ice shelf.

Nasa has released a striking photo of a rectangular iceberg floating in the Weddell Sea off Antarctica.

We tend to think of icebergs as jagged and pointy, with the bulk beneath the surface, and with a penchant for ruining DiCaprio romances.

Snapped by NASA's ICE mission, as part of Operation IceBridge, the giant tabular iceberg borne of the Larsen C ice shelf looks as though it was neatly cut from the wider ice shelf using a giant band saw.

NASA shared the image of the iceberg, which looks like it was perfectly chiseled away from a block of ice, on social media late last week.

"The iceberg's sharp angles and flat surface indicate that it probably recently calved from the ice shelf", the team writes.

Unlike the icebergs of non-tabular variety, such as the irregularly shaped berg that sunk the Titanic, these chunks of ice are distinguished by their flat tops, steep sides, and sometimes massive sizes.

USA issues warning to Russian Federation about helping Iran escape upcoming oil sanctions
USA sanctions on Iran's oil sector start on November 4 and analysts believe up to 1.5 million bpd in supply could be at risk. South Korea's crude imports from Iran fell to zero in September, data from state-run Korea National Oil Corp showed.

The agency also captured a triangular berg drifting in the Weddle Sea.

NASA scientist Kelly Brunt told LiveScience, "What makes this one a bit unusual is that it looks nearly like a square".

"We get two types of icebergs".

Categorized as a tabular iceberg, the square-like iceberg was estimated to be over a mile across.

"What makes this one a bit unusual is that it looks nearly like a square", Brunt said, adding that it's probably not very old since wind and water have yet to soften its sharp edges.

"In addition, IceBridge collects critical data used to predict the response of Earth's polar ice to climate change and resulting sea-level rise".
