Did you know that one can photograph a plant so clearly from a distance that it is likely to detect the health of its leaves? Or can you contemplate the possibility of taking a photograph of three similar-looking rocks, being able to distinguish them from each other due to spectral properties associated with their internal mineral content?

This and other drone-based geological imaging are made possible by the Merensky group for Aerial Geological Image Classification (MAGIC) at the University of the Free State (UFS).

Recently (24 March 2022), the President of the Hans Merensky Foundation (HMF), Dr Khotso Mokhele, signed a R11 million five-year research grant agreement with the UFS. Merensky research projects are currently limited to three South African universities – Stellenbosch University (for forestry research), the University of Pretoria (for avocados), and now the UFS.

Demonstration and application

Dr Mokhele, who is also the former Chancellor of the UFS, states: “When I walked into the MAGIC Lab, I knew that something special was going to happen here. What we are launching today will become a world-class and world-leading facility.”

According to him, Dr Hans Merensky, whose legacy is facilitated by the foundation, was one of the most influential geologists in South Africa. He discovered, among others, deposits of gold, platinum, diamonds, phosphates, and vermiculite. After several decades of operating in the geological sciences and with his knowledge of soil health, Merensky became a conservationist of note and played a key role in the establishment of the country’s agricultural practices.

“The main objective of the Hans Merensky Foundation is to promote and assist in the development of the resources of South Africa and neighbouring territories – particularly such natural resources as soil, water, flora, and fauna – and to promote the health and welfare of the inhabitants; more specifically, through research, experimentation, and demonstration and through the correlation and application of scientific knowledge.” 

“You have to take the knowledge and translate it into demonstration of what that knowledge can do, and then apply it,” says Dr Mokhele.

The grant is also evidence of Dr Merensky’s generosity. He is well quoted saying: “This country has given to me so much, that I am only too happy to be allowed to help it to develop in some way, and I am grateful to be able to give back to it a fraction of what it has given to me.” 

Next generation of scientists

The Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, said at the signing ceremony that this is an exciting project. “For us as a university, research and the development of the next generation of scientists are critical. This is part of our mandate. This project is one of those catalysts for the development of what the mandate is all about – research output, capacity building, and impact through our students and our research in a broader society.”

He thanked Dr Mokhele for facilitating the project and introducing the UFS to the Hans Merensky Foundation, having the confidence that the university has the capacity to deliver.  

“For Dr Mokhele, it is all about the science. To a certain extent, his driving force was to use science to make a difference in the lives of people,” says Prof Petersen. 

He continues: “The institution is highly committed to this project and will make sure that it receives the maximum support to make it a success.”

The grant has been allocated to MAGIC and funds will be used to support research programmes. “This includes student bursaries, staff salaries, capital expenditure acquisitions such as high-performance computers, as well as the drones that the project makes use of,” states Dr Martin Clark, Lecturer in the Department of Geology.

According to him, the group aims to develop drone-based geological imaging in South Africa, with specific attention to mineral and groundwater exploration endeavours.

Impacting society 
 
“What makes me excited about this project is how the research impacts society.  This includes developing geological imaging capacity in South African geologists with a 4IR skillset, ensuring that they remain competitive in a global market,” says Dr Clark.

He is also of the opinion that many industries will be able to see for themselves how this technology can improve their businesses. “Drone-based geological imaging can be quicker, cheaper, and safer for collecting much of the initial information that informs more expensive exploration processes, such as drilling. Additionally, it is non-invasive, and has little to no impact on the environment during data collection. Drones can also, in terms of safety, collect data from unstable rock walls – historically, geologists would have to take those measurements themselves, with rock falls resulting in a significant number of deaths every year.”

Recent research

Dr Clark says drone-based imaging has supported research initiatives in the Vredefort Dome. “Using drone-collected high-resolution images of meteorite impact melt rocks, along with field observations of how much and where foreign rock components were contained within (clasts), we could make a case for turbulent flow in the migration of impact melt material within the deep crust.”
 
He adds that three papers are currently underway, each predicated on drone imagery that enables new insights into geological processes or the ability to digitally translate geological information inside and outside the classroom.

The growing research group, with Dr Clark as the principal investigator, consists of one PhD student, two master’s students, and two honours students, with several postdoctoral research fellows to follow soon. 

The difference

Although several universities in the country have started using drones, the UFS has significant support to grow drone applications. With assets such as the high-performance computing cluster, very large drone-borne datasets can be resolved in record time.  

“The UFS also has a wealth of world-class researchers focused on topics such as farming and environmental management, who will be able to benefit from the drone infrastructure being established on campus. We are aiming to be the go-to geological drone imaging group in South Africa,” he says. 




About mineral and groundwater exploration


Dr Martin Clark explains that drones can carry several types of cameras, from regular photographic cameras that capture photos as we know it, to thermal cameras showing differences in hot and cold bodies, to spectral cameras capturing beyond what our eyes can see into other portions of the electromagnetic spectrum.  The MAGIC group mainly uses regular and spectral cameras for their applications. 

He says with mineral exploration, a high-resolution understanding of the geometry of rock bodies enables us to better identify where more costly mineral exploration techniques (e.g., drilling) should go.  This process allows for a better understanding of how geological areas have developed from a structural perspective – in essence, from where and how rocks have been displaced and deformed, and by association, the mineral deposits contained within.

“In terms of groundwater exploration, regular cameras are used to understand where rocks are fractured, where specific groundwater-influencing lithological bodies are located, and how they are orientated.” 

Dr Clark continues: “With spectral cameras, we can perceive the level of access that surface plants have to water resources. It is also possible to spot the distribution of plant types associated with, or strongly dependent on, available near-surface groundwater resources.  By using spectral data, which was historically collected from satellites, we can understand how areas of land have been affected by growing, shrinking, or shifting underground bodies of water.”

UFS Communication and Brand Management receives two prestigious international awards
2015-07-07

Lelanie de Wet, Lacea Loader and Leonie Bolleurs

The Department of Communication and Brand Management at the University of the Free State (UFS) received two of the six Gold Quill Awards – that were awarded to South African companies and institutions - at the International Association of Business Communicator’s (IABC) Excellence Gala ceremony in San Francisco, US on 15 June 2015.

The awards ceremony formed part of the 2015 IABC World Conference, which took place from 14-17 June 2015. The department received a Gold Quill Excellence Award for its social media campaign, UFS #FaceOfFacebook and a Gold Quill Merit Award for the B Safe Take Action campaign.

From the 15 countries that entered, a total of 120 Gold Quill Excellence awards and 189 Gold Quill Merit awards were awarded. Other South African award winners included Barclays Africa Group Limited, Mediclinic and the Cape Peninsula University of Technology (CPUT).

This is the second year in a row that the UFS has been recognised by the IABC for its communication projects. In 2014, the department was awarded the Jake Wittmer Research Award for a Stakeholder Perception Audit conducted in February 2014. The audit was considered – by the IABC - as one of the best breakthrough strategies used by a university to measure the perceptions of its stakeholders.This made the UFS the first tertiary institution in Africa to receive the research award. The stakeholder perception audit also received an Africa Gold Quill in 2014.

"Being recognised by a global association such as the IABC for the second time, is a great honour and I am very proud of what my colleagues have achieved by entering the two campaigns. Winning the awards is a true indication of what can be done when a team of expert communicators is committed towards engaging their target audiences with campaigns that speak of quality and innovation. The fact that the UFS is one of only two tertiary education institutions in the country to receive these prestigious awards, makes it even more special," said Lacea Loader, Director: Communication and Brand Management at the UFS.

IABC World and Africa conferences 2015 

The IABC is a global membership association with a network of 12 000 members in more than 80 countries, representing many of the Global Fortune 500 companies. It serves professionals in the field of business communication, bringing together the profession’s collective disciplines.

With the theme: Changing landscape: Informing the future, the 2015 world conference was attended by over 1 200 delegates from across the world. Delegates were offered an opportunity for learning, discovering, and connecting. Loader also made a presentation entitled ‘Award-winning measurement endorses sound reputation management strategy’ at the world conference.

The department will also be receiving two Africa Gold Quill Awards from the Africa chapter of the IABC for the same campaigns on 30 July 2015 in Johannesburg.

UFS #FaceOfFacebook Campaign

The university received a Gold Quill Excellence Award for its social media campaign, UFS #FaceOfFacebook. This initiative originated in the university’s commitment to its Human Project, which sets the standard for good behaviour and care.

Lelanie de Wet, Manager: Social Media and Website Content and project leader of UFS #FaceOfFacebook, said the project was born from the need to communicate with students. Thus a virtual friend, #FaceOfFacebook, was created. “Yearly auditions are being held to choose the new face representing the UFS on Facebook. Short video clips of the #FaceOfFacebook – whether it is attending events or communicating important messages - are posted on the UFS Facebook page. The successful candidate holds the title #FaceOfFacebook for 12 months.

“When I look at a campaign such as #FaceOfFacebook, from the time it took its first tentative steps in 2013, and see how it inspired staff and students alike, my heart swells with pride. Often you can see the impact you have made only in retrospect. The ripples you send into the world will inevitably create waves,” she said.

B Safe Take Action Campaign

The B Safe Take Action campaign of the university received a Gold Quill Merit award from the IABC.

The campaign was activated in September 2013. “It targeted on- and off-campus students and staff, aiming to create social ownership of personal safety, and to raise awareness of the safety measures put in place by the university,” said Leonie Bolleurs, Manager: Internal Communication and project manager of the campaign.

The campaign looked at a number of safety aspects, focusing not only on crime but also on being safe from road accidents and stress/burnout.

It is the second time this year that the BSafe campaign has been recognised for its innovative strategy. Earlier this year it received a PRISM Award (Gold) from the Public Relations Institute of Southern Africa (PRISA). The annual PRISM Awards are about recognising and celebrating great public relations campaigns.
