The history of fur seal research on Tristan da Cunha
Fur seal research at the Tristan da Cunha (TdC) Islands started during the 1970s (1974–1978). In its present form, the research continues through a next phase (2009–2019), and beyond.
Short description of the project
Using Subantarctic fur seals as bioindicators of environmental conditions and as tools for suitable management of natural resources, contributing to observing marine ecosystems in the TdC Islands, since 2019 and beyond, the aim is to: (a) determine the seasonal attendance patterns of primarily lactating adult females, from the smallest (incipient) population of the species in the world at Cave Point Peninsula, TdC, (b) measure and contrast the growth rate and/or weaning mass of pups at the Cave Point breeding colony (10 month nursing period), (c) collect scat (non-invasive) and whiskers (invasive) samples for diet analyses.
During this ‘takeover’ the team aims to service and/or retrieve the Attendance Pattern Automated System (satellite-linked) at Cave Point, collect and process fur seal scat samples to determine diet, and weigh pup/under-yearling fur seals (at around 290 days of age) to compare their weaning weights amongst years and with those of pups from other island populations (including Gough Island).
In everyday language
The fur seals breed and rest on the islands, and they feed at sea. The research team aims to determine (1) what the seals feed on when they are away during feeding trips, (2) how well the pups, which remain on land, grow on a diet of milk which they suck from their mothers when these return to land after each feeding trip, and (3) how far away from the island, and for how long, do the mothers of the fur seal pups have to remain at sea on each feeding trip to be able to sustain their pups until weaning.

Marion Island Marine Mammal Programme
This project is funded by: The National Research Foundation (NRF-SANAP), The Royal Society for the Protection of Birds (RSPB) and Tristan da Cunha Conservation Department (TdC Conservation Department).
Update posted by the Tristan Conservation Department (on Facebook, 09 October 2023):
“The weather has been very nice last week. The conservation team and professor Martian Bester managed to go to the caves to do seal work with the seal pups. It was a great success as they managed to weigh fifty pups. Martian has been working with the conservation department for fourty nine years but sadly this is his last year working with the conservation team as he is retiring”

A few hundred million years after the big bang, the first stars in the universe were born during a period known as cosmic dawn.
This epoch is uncharted territory: the first and only tentative detection of cosmic dawn was reported in 2018, thus opening a new window into the universe’s past that is ripe for new discoveries.
Telescopes aiming to study cosmic dawn must observe at radio frequencies (<150 MHz). These frequencies are exceptionally difficult to measure because of contamination from terrestrial radio-frequency interference and ionospheric effects.
Our team has demonstrated that Marion Island truly offers a South African geographic advantage for low-frequency radio astronomy. The radio-quiet environment of Marion is unparalleled, surpassing even the Karoo desert, which is one of the premier radio observatory sites and the future location of the Square Kilometre Array (SKA).
With its clean observing conditions, Marion Island gives a unique opportunity to deliver high impact science that is impossible to conduct anywhere else in the world.
Radio astronomy experiment (ALBATROS) on Marion Island.
The project has installed two radio astronomy experiments on Marion Island. The first, named PRIZM, is searching for the signal from cosmic dawn and has been operating for three years. We are continuing these observations, coupled with instrument upgrades and rigorous calibration campaigns in order to obtain a robust detection. The second experiment, ALBATROS (above), is a companion project that aims to image the radio sky at <30 MHz, improving upon the resolution of current results by a factor of 20-30.
We have proven the technology with a few pathfinder antennas, and we are building and installing additional antennas to complete the full ALBATROS array. Our work is well timed to take advantage of the current solar minimum. The reduced ionospheric activity may allow us to probe the sky at particularly low observational frequencies that are otherwise difficult or impossible to access.
Prof Kavilan Moodley is the Principal Investigator on the project hosted at The Astrophysics Research Centre (ARC) at the University of KwaZulu-Natal (UKZN). The Astrophysics Research Centre (ARC) is part of the College of Agriculture, Engineering and Science at UKZN. We strive to be a world-class centre of excellence for research and postgraduate training in astrophysics and related data-intensive science. The management of the project is done by Prof. H. Cynthia Chiang and Prof. Jonathan Sievers.

Today marks World Maritime Day, a global commemorative day celebrated every last Thursday of September. This annual observance serves as a tribute to the indispensable maritime industry and its pivotal role in connecting nations, enabling trade, and fostering economic growth. It is also an opportunity to reflect on the challenges facing the maritime sector and advocate for sustainable practices in an ever-changing world.
The International Maritime Organisation (IMO) has announced that this year’s World Maritime Day theme is “MARPOL at 50 – Our commitment goes on”. This theme highlights the 50th anniversary of the adoption of the International Convention for the Prevention of Pollution from Ships (MARPOL) on 2 November 1973. MARPOL focuses on preventing pollution of the marine environment caused by ships, whether it be from operational activities or accidental incidents.
International Cooperation and Sustainable Shipping
IMO currently has 175 Member States and three Associate Members. South Africa has been a member state of the IMO since 1995, sharing the responsibility to prevent pollution from ships.
In alignment with this year’s theme for World Maritime Day, we are reminded of the proactive measures taken by the country’s Department of Transport. In September 2022, they proposed amendments to the Marine Pollution (Prevention of Pollution from Ships) Act. One notable proposal is the potential increase in fines for ship pollution from R500,000 to R10 million, aiming to make non-compliance financially burdensome. These amendments specifically address the proper treatment and safe disposal of sewage from ships, as well as efforts to reduce greenhouse gas emissions that contribute to climate change and air pollution.
The South African research and supply vessel, the S.A. Agulhas II, is an example of a large ship that meets and complies with the regulations set forth in MARPOL. With its ice-breaking capability, the S.A. Agulhas II frequently navigates the Southern Ocean and Antarctic waters for scientific and research purposes as part of the South African National Antarctic Programme (SANAP).

The S. A. Agulhas II is a state-of-the-art vessel that has been constructed with effective waste management systems. It is equipped with an advanced in-house waste water treatment system that efficiently treats liquid waste, sewage, and greywater before storing or disposing of them within permitted limits. Grease traps are utilised to manage greasy liquid waste, and a comprehensive garbage management plan is in place for all solid waste. These measures ensure adherence to both national and international maritime waste policies, while also supporting South Africa’s leadership in marine and Antarctic research expeditions through SANAP.
Celebrating South Africa’s Seafarers
The SANAP and SAPRI have published The Maritime Interview Series to pay tribute to the seafarers who play a crucial role in the success of the maritime industry. These individuals dedicate their lives to seamanship and are responsible for navigating the S.A. Agulhas II across the Southern, Indian, and Atlantic Oceans for various marine and Antarctic research expeditions. The interview series features six seafarers who work on the S. A. Agulhas II through the vessel managing agent, African Marine Solutions (AMSOL). To learn more about these local heroes in the maritime industry, please visit the links provided below.
The Maritime Interview Series 2023
World Maritime Day encourages us to reflect on the importance of sustainability, safety, and international cooperation in ensuring the enduring prosperity of this sector. As we chart a course toward a more sustainable future, let us acknowledge and appreciate the dedication of those who keep the world’s seas and oceans alive. Together, we can work towards safeguarding these invaluable natural resources for generations to come.
To our local seafarers, we say THANK YOU, for your dedication and endurance while at sea!
