Arctic glaciers are melting faster than expected fuelling a rise in sea levels, which experts believe could cost the UK billions of pounds.
Philip Goodeve-Docker and his team mate Andy Norman were both "rookies to the Arctic" according to Mr Norman.
Writing on his website before the trip, the 33-year-old former IT professional said he was "setting foot for the first time in the Arctic Circle" and described Mr Goodeve-Docker as "completely new to the Arctic and indeed this adventure lark" but added that his friend had been "training furiously".
Mr Norman and Mr Goodeve-Docker undertook the unsupported crossing with experienced expedition leader Roan Hackney.
The trio was supported and monitored during the trip from the UK, managed by a world leader in managing Greenland expeditions.
Mr Norman and Mr Hackney remain in hospital.
Well-wishers continued to pledge donations to Philip Goodeve-Docker's nominated charity today in tribute to the adventurer.
Mr. Goodeve-Docker died on Sunday after he and his friends Andy Norman and Roan Hackney attempted to cross the world's second largest icecap unsupported.
He undertook the challenge in a bid to raise more than £5,000 for the The Queen's Nursing Institute.

We are aware that British nationals were in difficulty during an expedition in Greenland and have been rescued by the authorities. Sadly one of the men, Philip Goodeve-Docker, died. The two other British nationals are in hospital.
We are providing consular assistance to their families at this time.

We wanted to let everyone know that on Sunday morning we had a phone call to confirm that Philip sadly died.
To our son, brother and friend, we are so glad that you were on your adventure and expedition that you had wanted to do for so long. You will be unbelievably missed and your memory cherished. xx

This is one of the great polar challenges, through which we face such dangers as polar bears (not cute and cuddly), crevasses up to 500 metres deep, polar winds, temperatures of 5C to -50C, plus the horror of 3 men with one tent & no washing.
Part of my reasons for this frankly nutty adventure is my Grandfather, Patrick Pirie-Gordon, who passed away two years ago. Amongst his achievements were his key roles as Treasurer and Honourary Vice-President for the Royal Geographical Society, helping fund polar exploration, and Treasurer for the QNI.
A British man has died while attempting to cross the Greenland ice cap with two friends, the Foreign Office has confirmed.

The two other British men remain in hospital.
Camp Barneo, otherwise known as the North Pole Camp, is located just 49km from the top of the world. It is set up every year from scratch, and serves as a base for excursions to the Pole. Here are some other facts about North Pole's floating ice camp:
- By the end of April it starts melting, making Barneo the most temporary runway in the world, open for business less than one month every year.
- This year, work on Barneo will have to wrap up about a week earlier than usual, as the ice melts faster than ever before.
- Barneo is constantly moving as northerly winds push the floating camp towards the southeast at up to 0.5mph.
- Every year in March 50 tons of equipment – everything from food supplies to bulldozers - are dropped onto the camp by parachute.
Melting glaciers in the Arctic are increasing the flood risk to the UK and could end up costing us billions of pounds, according to a top environmental official.
Glaciers are responsible for around half of the rise in sea levels to date.
Leading scientists have told ITV News that Arctic glaciers are melting faster than expected and that the UK needs to prepare for more frequent flooding as a result.
In his latest report on the changing Arctic, our Science Editor Lawrence McGinty has been to meet some glaciologists in the Norwegian archipelago of Svalbard:
