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.

Today, 05 March, marks the one-year anniversary of the discovery of the Endurance, the sunken ship of Sir Ernest Henry Shackleton. Two images taken on the Endurance22 expedition were included in the National Geographic Pictures of the Year (2022).
In February and March 2022, a major international scientific expedition explored one of the coldest, harshest and most remote places on earth, to find Sir Ernest Shackleton’s lost ship, the Endurance. The Endurance22 expedition was the first to locate and investigate Sir Ernest Shackleton’s lost ship, which sank in the Weddell Sea in Antarctica in 1915.
What a privilege it is for the South African research and supply vessel, with ice braking capacity, the S.A. Agulhas II, to have been selected as the main infrastructural support for the Endurance22 expedition. The S.A. Agulhas II and its crew is part of this very special day in history and to top it off, National Geographic has included an image of the S.A. Agulhas II in its 2022 Pictures of the Year selection (see image below). The image was taken by Esther Horvath, the official photographer aboard during the Endurance22 expedition. The image shows the S.A. Agulhas II maneuvering among ice floes in the Weddell Sea in stormy weather. National Geographic states that “out of millions of images, just 49 were selected as the best photos of the year”.

Esther Horvath’s story behind the photo:
The ship was busy for 24/7 as time was tight for the search. I took the photo on the night of February 26, 2022 on the S.A. Agulhas II in the Weddell Sea while the ship was navigating between thick ice floes. Navigation was possible using satellite imagery over the ice floes. During the night after completing one search, the ship was moved to the next search area. I was standing in the snowstorm above the bridge outside on the deck called the “monkey island.” It was very difficult for me to open my eyes because the snow was poking my eyes like needles. I could only stand there for a few minutes because the wind and the very cold temperatures bit into my bones.
Another image selected for the National Geographic 2022 Pictures of the Year is the image of the stern of the Endurance wreck, taken by Nico Vincent and his autonomous underwater vehicle (AUV) team.

Esther Horvath is a contributor photographer for National Geographic and a photographer for the German Alfred Wegener Institute for Polar and Marine Research. Since 2015, her work has focused on documenting climate research and scientific expeditions in the polar regions with behind-the-scenes science stories. By documenting the work of scientific groups and the lives of scientists who provide important climate data, Esther hopes to help people better understand what is actually happening in the polar regions and, in collaboration with scientists, raise public awareness of this fragile environment. In 2020, Esther won 1st prize at the World Press Photo Awards in the Environmental single category. In 2022, she received the Infinity Award from the International Center of Photography in New York for her work raising awareness about conservation, environmental justice, and climate change. She is the author of “Into the Arctic Ice”, which chronicles the largest scientific expedition to the Arctic Ocean of our time, called MOSAiC.

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.
