Louzanne Coetzee and her guide Estean Badenhorst won the silver medal in the 1 500 m in a new African time at the Paralympics in Tokyo on Monday.

It’s been eight years of waiting, but Louzanne Coetzee will finally hang a medal around her neck, and this on the biggest sporting stage in the world.

Coetzee won the silver medal in the 1 500 m women’s T11 final at the Paralympics in Tokyo on Monday (30 August 2021) morning. In the process, she and her guide, Estean Badenhorst, set a new African record (4:40.96).

They are both former University of the Free State (UFS) students, and Coetzee is a resident on the Bloemfontein Campus. 

“I have been competing for eight years and this is my first medal. I’m just overwhelmed. I couldn’t have asked for a better race, a better guide, and better preparation. I’m just very thankful for how everything went down,” Coetzee said.
The race took place at 32 degrees with a humidity percentage of 70 plus. Coetzee’s time was only 2.04 seconds off the previous world record. 

She has had a stunning Games so far. In Sunday’s heat, she improved her personal best from 4:51.65 to 4:49.24 and ran another eight seconds quicker on Monday.

It was also a personal triumph for Coetzee, who experienced the disappointment of being disqualified five years ago at the Rio Games, after a ruling that her guide had stepped in front of her. 

Prof Francis Petersen, UFS Rector and Vice-Chancellor, saluted Coetzee. “We are tremendously proud of what she has achieved throughout her athletics career. She has represented the country numerous times at international sport events and winning a silver medal and setting a new African record is the culmination of hard work and exceptional endurance.” 

“The entire university community was rooting for her; she has done us and her country extremely proud,” Prof Petersen said.

Coetzee still has the T12 marathon on Sunday on her schedule.

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.
