An enormous iceberg estimated at about one-and-a-half times the size of greater Paris has broken off in Antarctica.

The European Space Agency (ESA) says radar images from the Copernicus Sentinel-1 mission show the 1270 square kilometre iceberg breaking free from the northern section of Antarctica’s Brunt ice shelf last Friday.

The ESA says glaciologists had been closely monitoring the many cracks and chasms that have formed in the 150 m thick Brunt ice shelf in recent years.

A new crack was spotted in late 2019 on an area of the shelf north of the McDonald Ice Rumples, and it was reported to be “heading towards another large crack” located close to the Stancomb-Wills glacier tongue, the ESA says.

“Although the calving of the new berg was expected and forecasted some weeks ago, watching such remote events unfold is still captivating,” Mark Drinkwater of the ESA has said.

“Over the following weeks and months, the iceberg could be entrained in the swift south-westerly flowing coastal current, run aground or cause further damage by bumping into the southern Brunt ice shelf,” he said.

“So we will be carefully monitoring the situation using data provided by the Copernicus Sentinel-1 mission,” he said, referring to the mission run by the ESA.

The iceberg has been informally dubbed “A-74” by glaciologists.

Antarctic icebergs are named from the Antarctic quadrant in which they were originally sighted, then a sequential number. If the iceberg breaks, a sequential letter is then added.

The ESA says the calving does not pose a threat to the presently unmanned British Antarctic Survey’s Halley VI Research station, which was relocated in 2017 after the ice shelf was assessed as unsafe.

#Shipping - Shipping routes south of the Equator could be threatened by a giant iceberg the size of New York's Manhattan Island that's broken off a glacier in Antarctica.

BBC News reports that a British research team has been tasked with tracking the massive ice floe, which broke free from the Pine Island Glacier in July and is now drifting in the Southern Ocean between New Zealand and Chile.

A previous iceberg in the same area drifted into the Drake Passage between Cape Horn and the South Shetland Islands, and if the new discovery took the same trajectory it could pose a serious threat to international shipping lanes.

#TITANIC - The Irish Times has highlighted "one of the less well-known tales of the disaster" of the Titanic, regarding two tennis champions who went on to enter that sport's hall of fame.

The story of Richard Williams and Lark Behr was told at an exhibition of sporting memorabilia in Yorkshire last month by collector Robert Fuller.

Williams, who was 21 at the time, was headed to the US Championships when the Titanic went down. He was among those rescued by the Carpathia after hours in frozen water, and fought with that ship's doctor who wanted to amputate his legs.

His persistence paid off, as just months later he was in the quarter finals of the US Open, a context he would win in 1914 and 1916, not to mention the Wimbledon doubles title in 1920 and Olympic gold in the mixed doubles in 1924.

Behr - who reportedly proposed to his fiancée on a lifeboat - also had a glittering career after the tragedy, reaching the doubles final at Wimbledon and number three in the US rankings.

Meanwhile, BBC News has posted an infographic that follows in detail the critical moments leading up to and after the Titanic struck the iceberg that sealed its doom at 11.40pm on Sunday 14 April 1912.
