What are your plans for this takeover?
Into our 41st uninterrupted year of continuous monitoring! Takeover is mostly dedicated to training the new overwintering personnel, because most of the action (from a seal perspective) on the island take place outside takeover timeframes. Many long-term questions, aimed at understanding the ecology of the various species populations and their interactions with a changing environment, are pursued.
What are the main interest of the MIMMP in the sub-Antarctic region?
We are interested in how seal and killer whale populations change as the environment changes.
In more detail:
MIMMP does long-term ecological monitoring and research of four marine mammal species (Southern elephant seals, Antarctic – and Subantarctic fur seals, and Killer whales) at Marion Island. Focused primarily on population and foraging ecology, interactions between species and with their changing environments.

Tomorrow, 22 April 2023, is Earth Day!
We support environmental protection. One way to encourage people to protect the environment is for environmental scientists to communicate scientific findings in a way that is digestible for your audience.

It is with great pleasure that we share that Dr Thomas Ryan-Keogh will be a speaker at TEDx Johannesburg Countdown to talk about the impacts of climate change on the Southern Ocean. “His talk will contribute towards the dialogue and action on climate change and will showcase how the CSIR is contributing towards global research efforts on the impact of climate change in Antarctica and the Southern Ocean”.
Book your seat today!
TEDx Johannesburg is a great platform where “remarkable people doing great work can amplify their ideas on the world wide web”.
“We believe that their ideas, delivered at our sought-after events, and distributed via video on the web, will change the world” – TEDx Johannesburg.
At this event, Tommy will have only 12 minutes to share his recent oceanographic research findings, “which showed that the natural carbon cycle in the Southern Ocean is being impacted and that it could be causing even more harmful climate impacts. These findings were recently published in the top-rated journal Science under the title: Multidecadal trend of increasing iron stress in Southern Ocean phytoplankton” – CSIR

Tommy is the Chair of the Association of Polar Early Career Scientists of South Africa. APECS-SA is a “National Committee of APECS international, a non-profit and voluntary organization which focuses on improving communication between young polar researchers on a local and international level.”

The S.A. Agulhas II is on her final stretch of the first oceanographic leg to the sub-Antarctic Marion Island. The voyage has been overall calm, with easy and moderately sea and swells, reaching no more than 3 meters, in the past two days.
The 80th Marion Island overwintering team and land-based takeover personnel will soon reach their destination. The takeover is packed with scientific objectives, for both land and ship-based science groups, which will be shared over the next few weeks.

Departure: Port of Cape Town to Marion Island | Evening of 15 April 2023 |
Expected time of arrival: Marion Island | Evening of 19 April 2023 |
S.A. Agulhas II last communicated position (18 April 2023, 23:59) | LAT: 40° 40.6' S
LONG: 27° 45.5' E |
Destination: Marion Island | LAT: 44° 9.1' S

Mayibongwe Buthelezi, a PhD student from University of Pretoria, is currently participating in the 30th Atlantic Meridional Transect cruise (AMT-30).

The AMT (Atlantic Meridional Transect) cruises are a series of research voyages conducted annually across the Atlantic Ocean, from the UK to the Caribbean, to study the ocean’s biogeochemistry, ecology, and physical properties. The cruises are multidisciplinary and include scientists from around the world. As part of the cruise, samples are collected at multiple depths and locations along the transect (read more about AMT here and here).

SANAP Project Involved: Enhanced insights regarding the ecology, evolution and function of marine microbiomes
Project Principal Investigator: Prof Thulani P. Makhalanyane
The South African Research Chairs Initiative (SARChI) Chair in Marine Microbiomics has a SANAP funded project focused on understanding microbiomes in the Southern Ocean and South Atlantic. The project titled “Enhanced insights regarding the ecology, evolution and function of marine microbiomes.” As part of this project, we have initiated a series of collaborative activities to access and join international cruises through the EU funded AtlantECO program.
Mayibongwe Butlelezi, a NRF/SANAP funded PhD student from the University of Pretoria, was selected to join this 6-week cruise aboard the Discovery. AMT30 has departed from the Falkland Islands on 21 February 2023. As far as we know, Mayi is the sole South African representee on the cruise. His project is focused on understanding the role played by marine microorganisms in the sulphur cycle. Specifically, Mayi will collect samples using protocols developed as part of the AtlantECO project to study microbiomes along the water column and to specifically quantify DMSP (Dimethylsulfoniopropionate).

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.
