In celebration of International Women’s Day, we came in contact with Tanganedzani “Tanga” Tshitavhe. She is an Assistant Meteorological Technician, for the South African Weather Service (SAWS), on the sub-Antarctic Marion Island.
This is a strong woman, with passion for her work and the sub-Antarctic environment. She also has a great sense of humour.
This is her message for all women out there:
“Today we celebrate the resilience, strength, grace, and beauty of women all around the world. On this day, let’s remember the importance of equity, work towards creating a more inclusive world, and honour the contributions and achievements of women”.
I mentioned she has a great sense of humour:
Today we are having a clear sky (sunshine) on Marion Island and as the Weather-Lady, here is a Sun pun.
Question:
Why is the Sun not very heavy to carry?
Answer:
Because it is very light
Wishing you all a happy International Women’s Day day filled with joy and laughter.

World Wetlands Day, is celebrated every year on 02 February. On this day, in 1971, the Convention on Wetlands of International Importance (Ramsar Convention) was signed in Ramsar, Iran.
World Wetlands Day is celebrated to to “raise awareness and understanding of what wetlands are and how we can contribute towards restoring them through making conscious choices, becoming persuasive voices and taking bold actions” (read more here).
What is a wetland?
A wetland is defined as the land which is transitional between terrestrial and aquatic systems where the water table is usually at or near the
surface, or the land is periodically covered with shallow water, and which land in normal circumstances supports or would support vegetation typically adapted to life in saturated soil (1).
Why is wetland restoration so important? Listed below are a few benefits of wetland restoration:
- Enhanced biodiversity
- Improve water supply
- Store carbon
- Reduced impacts from flooding
- Improve livelihoods
- Enhance well–being
- Protection of agricultural resources (1; 2)
Is your role in wetland restoration important?
Yes! Our individual and collective actions have an impact (1).
What can you as individual do to help protect and preserve wetlands?
- Participate in programs that help protect and restore wetlands.
- Report illegal actions such as unauthorized wetland fill or dredging activities to government authorities
- Pick up litter and dispose in appropriate trash containers. Keep surface areas that wash into storm drains clean from pet waste, toxic chemicals, fertilizers and motor oil, which can eventually reach and impair our wetlands.
- Use native species when planting trees, shrubs and flowers to preserve the ecological balance of local wetlands.
- Avoid wetland when you are expanding your house.
- Use phosphate-free laundry and dishwasher detergents. Phosphates encourage algae growth, which can suffocate aquatic life.
- Use non-toxic products for household cleaning and lawn and garden care. Never spray lawn and garden chemicals outside on a windy day or on a day that it might rain and wash the chemicals into waterways.
- Enjoy the scenic and recreational opportunities wetlands offer, while preserving their integrity for future generations by minimizing the use of heavy equipment and staying in designated visitor areas where available (3).
Did you know that the South African Prince Edward Islands (Prince Edward Island and Marion Island) is declared as Wetland of International Importance?
The Prince Edward Islands was declared Wetland of International Importance: Ramsar Site No.1688, on 22 May 2007. The conservation and management of this site falls within the responsibility of the Directorate: Southern Oceans and Antarctic Support of the Department of Forestry, Fisheries and the Environment.

“SCAR’s mission is to advance Antarctic research, including observations from Antarctica, and to promote scientific knowledge, understanding and education on any aspect of the Antarctic region. To this end, SCAR is charged with the initiation and international co-ordination of Antarctic and Southern Ocean research beneficial to global society. One of the most effective ways to do this is to bring researchers together to share their latest results, discuss new ideas, and provide opportunities to develop new projects” – www.scar.org
SCAR expanded its biennial business meetings to include an Open Science Conference (OSC). This year’s open science conference was held from 1 – 10 August 2022, hosted by India. It made it possible for participants and attendees to discuss current results and develop future projects. The conference included plenary, parallel and satellite events, as well as workshops. Business meetings of the science groups were held before the open science conference.

South Africans participated and attended various sessions during the conference (see details below):
- Keynote speaker Katye Altieri: “Stable isotopes as a tracer of reactive nitrogen emissions and aerosol formation in the Southern Ocean”.(link)
- Bettine van Vuuren chaired a mini-symposium.
- Christel Hansen, Mia Wege, Geoff Grantham, and Charne Lavery were session convenors.
- The business meetings were attended by Bettine van Vuuren, Sarah Fawcett, Ria Olivier, Christel Hansen, Anche Louw, Charney Lavery, Geoff Grantham, Thulani Makhalanyane and Werner Nel.
Presentations delivered:
- Geoff Grantham: The Age And Chemistry Of Granitic Gneisses From The Western H.U.Sverdrupfjella, Maud Terrane, Western Dronning Maud Land, Antarctica. (link)
- Ria Olivier: Digging into the Past; An archive as a tool to compile and establish a timeline of human impact in our polar heritage (link); Collaboration of South African Researchers in an Extreme Cold Environment. (link)
- Marcel du Plessis: Insights from the SO-CHIC Expedition: what have we done and where are we now? (link)

Antarctic Legacy of South Africa communicated South Africa’s participation and conference-related announcements on Twitter (47 Tweets). A highlight was the session on the discovery of Shackleton’s Endurance, where South Africa was frequently mentioned during the talk.
What is to come:
- SCAR Delegates Meeting (5-7 September 2022)
- All the best to Bettine van Vuuren and Tracy Klarenbeek attending as SA representatives.
All posters and presentations can be found on the ALSA digital archive.
The conference virtual site is still available – if you have missed out on any sessions you can listen to the recordings, and all abstracts and posters can still be downloaded.
