The Endurance 's ill-fated trip, marked The End of the "Heroic Age " of Antarctic research

It will take a monumental effort to locate the legendary ship of Antarctic Explorer Ernest Shackleton .

This is the conclusion of scientists to find the, the Endurance , which sank in 3,000 m of water in the Weddell Sea in 1915.

The Team says that the sea-ice in the Area above The Wreck is almost always thick and extensive.

It means that most of the expeditions would fight, even to get Close Enough to start searching.

The fact, amazingly well, achieved the recognised wreck location, and launch an Autonomous underwater vehicle (AUV) to survey the sea floor.

But this robot broke the communication with The Expedition with the research ship SA Agulhas II, approximately 20 hours in the mapping process, and was never seen again.

What have recognized it might, we will never know. Encroaching sea ice, forced to leave The Team , its AUV and evacuation of the Area .

An AUV was launched to search for more stamina, but it was lost under the sea-ice-cream

The Expedition , scientists have now written, in this barren sector of the Antarctic. They also have yacht's some advice for all the people who might want to search Shackleton polar.

"finally, you find the Endurance on the sea floor would require a favourable sea-ice conditions in the Central-Western Weddell Sea , including the available results of the wide (Open Water )," said Dr. Christine Batchelor from the Scott Polar Research Institute (SPRI) in Cambridge, UK.

"in addition, a two-ship operation may be necessary to break the ice and to successfully launch and recover an Autonomous underwater vehicle," she told Bbc News .

Shackleton's story is one of The Most extraordinary stories from the "Heroic Age " of Antarctic exploration.

Trapped in sea ice for over 10 months, his Endurance ship drifted around the Weddell Sea until finally it was broken by the clods, and fell into the depth. As Shackleton and his men then escape on foot and in the rescue boats-this is The Stuff of legend.

this is Where the Endurance was known; The Ship 's captain, Frank Worsley records The Position with a sextant and theodolite. But the reach of this part of the Weddell Sea , East of the Larsen ice shelves on the Antarctic Peninsula , is extremely difficult, also for modern ice-breakers.

The 2019 team satellite data used to assess the concentration of sea-ice at The Wreck from 2002 to The Present day. The Group shows that in 14 of the 18 years reviewed, the conditions were "bad". The nearest Open Water could be 200km or more away.

One of the "good" years was in 2002, The German research ship "Polarstern" allowed a very close pass and some limited mapping (echo sounding) of the sea floor. The Resolution was never sharp enough to recognize the Endurance , but it yielded interesting insights into the nature of the sea Bed , with encouraging consequences for the probable condition of The Wreck .

the Endurance is probably on flat ground was undisturbed, landslides, either by erosion or by water. Sediment deposition is also likely to be too low, at a rate of less than 1mm per year.

"So, it's not covered by sediment," said Prof Julian Dowdeswell, Director of SPRI.

"It will not be damaged by something coming from the side. And at 3000 m, it is way below the maximum depth of an iceberg keel. Glaciologically and Geophysics pre-charged-physically - stamina unharmed should be. "

all of This is a good sign for future attempts to find what The Most famous wrecks.

SA Agulhas II: A Future Search , is going to have More Than a large polar research ship

It is certainly at The Top of The List of targets for David Mearns , whose expertise is in the search of lost ships known worldwide.

He Said : "It is a shame that in 2019, the search failed in their attempt to locate the Endurance wreck, so they had The Best ice conditions seen in The Past 17 years.

"That proves my long-held assertion that a" single-ship " expedition is too risky, even with good ice conditions, and that The Key to finding the Endurance is a totally different approach," he told Bbc News .

Prof Dowdeswell is pessimistic that someone would Fund a mission with the sole goal of the localization of the Endurance .

Most of the future efforts, he says, "add-ons" to more scientific expeditions in the region - as was the case with his venture in The Past year, the primary objective of the investigation of the melting and the retreat of the Larsen had a ice shelves.

"Yes, you want to AUVs and remotely operated vehicles (ROVs) to locate and photograph The Wreck , but it is a great opportunity to own this state-of-the-art vehicles, in the science; and there is No Doubt that we will be nothing done, how much science without the pieces of the kit on Board, and we would not have had that equipment on Board, unless we were in search of Shackleton's Endurance . There is a balance between exploration and science," He Said .

Prof Dowdeswell and colleagues published their Report .
