The members of the Kovsie tennis team are, from the left, front: Danique Reynders, Reze Opperman, Daniel de Villiers, Ester de Kock, Lienke de Kock, Anandhi Botha, and Janine de Kock (team manager); back: Marnus Kleinhans (coach), Heinrich Willemse, Emke Kruger, Arne Nel, Ryk Kleinhans, Handre Hoffman, and Ruben Kruger.

The country’s number one student team and South Africa’s second-best club. This is the bragging rights earned by the University of the Free State’s (UFS) tennis team after winning the 2019 University Sport South Africa (USSA) Tennis Championship. 

The Kovsie team claimed their ninth consecutive USSA title on Friday 6 December in Stellenbosch, winning all their matches. The team comprised both men and women – a combination which has been in place since 2010. Since 2010, there has been only one name on the USSA trophy, with the Kovsie team winning from 2010 to 2015 and again from 2017 to 2019. The competition was not hosted in 2016.   

In the 2019 USSA final against Maties, Kovsies was declared the winner, with the score 7-1 after completing seven singles matches and one doubles. A match consisted of four men’s singles, four women’s singles, two men’s doubles, two women’s doubles, and two mixed doubles. 

Arne Nel, Ruben Kruger, Handre Hoffman, Heinrich Willemse, Ester de Kock, and Reze Opperman all won their singles in straight sets. Kruger and Willemse combined for a win in the only doubles match.

On their road to victory, the team had wins over the North-West University (Mafikeng Campus), the University of Cape Town, Stellenbosch University, and the University of Pretoria. The victory over the University of Pretoria in the semi-final was revenge for the Sun City University Championship in March, where they denied Kovsies a fourth consecutive crown in that competition.

Another feather in the cap for Kovsie tennis was that two team members, Willemse and Kruger, along with two management members – Marnus Kleinhans and Janine de Kock, respectively UFS tennis coach and team manager – were chosen for the South African team to the World Student Games in July.

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.
