Antarctica has been called the least understood continent of Earth. Recently, data from a discontinued European satellite reveals that the ice sheet beneath eastern Antarctica is a graveyard of continental remnants. The research, led by Jörg Ebbing, a geophysicist at Kiel University in Germany, reported their discovery earlier this month in Scientific Reports. They created 3-D maps of the southernmost continent’s tectonic underworld and found that the ice has been concealing wreckage of an ancient supercontinent’s spectacular destruction. The pieces may have been assembled a billion years ago, when the supercontinent Rodinia was built, or as recently as 500 million years ago, when another supercontinent, Gondwana, came together. Either way, what has been found beneath Antarctica is part of what’s left after Gondwana’s dissolution, around 160 million years ago.
Why is this important to know? Because knowing the rock that sits beneath the largest ice sheet in the world will help understand global warming, as subglacial geology influences how ice shifts as the climate changes.

We are leading a journey to Antarctica in March 2019. Send us an email at firstname.lastname@example.org to find out more about this epic voyage.
A tear-drop shaped island, Sri Lanka, the resplendent land, southeast of the Indian Subcontinent, is one seeped in history dating back to at least 125,000 years. Formerly known as Ceylon, this land is a centre of religion and culture, encompassing Buddhism, Hinduism, Christianity and Islam. Its geographic location and deep harbours made it an important location of the Silk Route.
With a 103 rivers, several estuaries and lagoons, Sri Lanka’s dense mangrove system spanning over 7000 hectares plays a vital role in buffering tsunami-like waves. Sri Lanka is one of the 25 biodiversity hotspots in the world, with the highest biodiversity density in Asia.
Stilt fishing is one of the most interesting traditional fishing methods of Sri Lanka, with records indicating it began just after World War II. This method was a common practice till the tsunami hit pristine island in 2004. This graceful skill, almost like a dance on a pole, is now seen during dawn and dusk in the southern coastal towns of Sri Lanka.
One of our memorable journeys to Sri Lanka was with the team of Nicobar. We organised an itinerary to some of our favourite locations, and they created a beautiful journal of their experience. Have a look at the online version here.

Pack for a Purpose has not only reformed the physical infrastructure for education, in the case of Ramathra, but the entire mood with which children approach schooling.

In 1959, world governments came together to sign the Antarctic Treaty, to ensure that Antarctica was used only for peaceful and scientific research purposes. In 1991, they proposed a 50-year agreement, declaring the great white continent as a natural reserve, banning mining and drilling activity for mineral resources. Although Antarctica remains unexploited, we can see the effects of climate change through retreating glaciers and rising temperatures in the region.
After a successful launch in the International Year of Sustainable Tourism in March 2017, Ibex Expeditions has pledged to promote Antarctica as a destination, where the journey has a purpose–to create a movement of building awareness around protecting such pristine spaces. Join us for our next voyage to the last true wilderness on Earth.
