The University of the Free State (UFS) recently had the honour of hosting a thought-provoking guest lecture delivered by His Excellency Dr Reuben E Brigety II, the United States Ambassador to South Africa. Held on 23 April 2024 at the Centenary Complex, on the UFS Bloemfontein campus, the lecture delved into the vital role of higher education in fostering and safeguarding democracies.

Describing the occasion as a pivotal moment for the institution, Prof Francis Petersen, Vice-Chancellor and Principal of the UFS, articulated, "Having the United States Ambassador to South Africa visit our institution and deliver this guest lecture presents an invaluable opportunity. It allows us to gain unique insights into the parallel dynamics and challenges facing our sister democracies, particularly as both our countries approach significant electoral periods.”

Dr Brigety, in his address, underscored the significance of higher education in the context of Freedom Day, celebrated in South Africa on 27 April 2024. He emphasised the role universities play in advancing democratic values, drawing upon the UFS motto, “In truth is the light of wisdom” to elucidate this connection. Highlighting the inspirational figure of the late Charlotte Maxeke, a prominent social and political activist, Dr Brigety noted her pivotal role in both South African and American contexts.

Maxeke, a graduate of Wilberforce University, and her husband Marshall Maxeke, founded the Wilberforce Community College upon returning to South Africa. Dr Brigety underscored the significance of Maxeke’s commitment to civil liberties and education, along with her enduring ties to the Wilberforce University network, in shaping subsequent generations of activists and leaders.

Moreover, Dr Brigety stressed the importance of collaborative efforts between South African and American universities amidst today’s complex global challenges. He advocated for initiatives such as collaborative research projects, joint academic programmes, and student exchanges, citing their role not only in knowledge creation but also in fostering mutual understanding and strengthening bilateral relations.

In concluding his address, Dr Brigety urged the audience to emulate the examples set by individuals like Charlotte Maxeke and Prof Jonathan Jansen, the former Rector and Vice-Chancellor of UFS. He encouraged them to champion the cultivation of the next generation of leaders, thinkers, and change-makers.

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

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.
