Leanne Manas

Leanne Manas is a multiple award-winning broadcast anchor, MC, motivational speaker, businesswoman, UNHCR Goodwill Ambassador, and a renowned leader on the South African media circuit. From Oprah Winfrey to Nelson Mandela, Leanne has interviewed an impressive range of public figures, heads of state, thought leaders, and local and international celebrities. She has also been at the forefront of bringing South Africans some of the biggest news stories over the past two decades. 

She is instantly recognisable as the face of morning television – as anchor of Morning Live, a hard-hitting news broadcast that she has been hosting since 2004. She has been the face of the vast majority of breaking news events in an ever-changing South Africa, most notably the death of Nelson Mandela, the dramatic resignation of Jacob Zuma as RSA President, and the death of the Mother of the Nation, Winnie Madikizela Mandela. She has also anchored four general elections, three provincial elections, and four presidential inaugurations. 

Her career has crossed international borders, broadcasting in the United Kingdom, France, the UAE, Mauritius, Ghana, Kenya, Gabon, Switzerland, the Netherlands, and the United States of America. Broadcasting every day throughout a global pandemic has been the latest event that she has been part of. The total shift of how media is consumed has been a fascinating part of her journey. Leanne has been quoted as saying, “Being able to witness and tell the story of our ever-changing lives is my greatest honour.”

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.
