University of the Free State (UFS) Alumni may be based all around the world, but the United Kingdom (UK) Alumni Chapter aims to reconnect with all those members.

The UK Chapter is a hub of a developing UFS international programme. “We want to provide an opportunity for alumni to share their university experiences with wider audiences,” explains Carmenita Redcliffe Paul, Assistant Director: Alumni Relations and Business Development at the UFS.

Platform to celebrate successes

“The programme aims to provide a platform to alumni to celebrate their successes and provide a window to the landscape of the life and times of the university and the people who shaped it.”

“We also want to celebrate the diversity of our former students and the many touchpoints which unite them.”

Two key projects, Global Citizen and Voices from the Free State, came to life as a result of the collective collaboration of this chapter. The Global Citizen invites people in a series of “courageous conversations” to rethink their relationship with the world. Voices from the Free State is a series of personal podcast narratives by outstanding alumni wherein they reflect their experiences at the UFS. They tell their stories and explain how their university years shaped their future and paved the way to their respective successes.

Relevant association with the UFS

“Furthermore, they motivate why their ongoing association with the UFS is still relevant and important,” says Redcliffe Paul.

The UK Alumni Chapter is led by alumni Francois van Schalkwyk and Keenan Carelse and supported by Adrienne Hall.

Redcliffe Paul says Carelse and Van Schalkwyk have been instrumental in the Voices from the Free State initiative as they are strategically and operationally invested. They create and co-host the podcast series.

Van Schalkwyk is an entrepreneur and innovator consulting with clients globally. Carelse is employed in the healthcare sector in the UK.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
