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.

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”
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!

On 19th of June, the world comes together to celebrate World Albatross Day, an annual event dedicated to raising awareness about these magnificent seabirds and the conservation challenges they face. World Albatross Day serves as a crucial platform to educate and inspire action to protect these iconic ocean wanderers. With their graceful flight and important ecological role, albatrosses deserve our attention and concerted efforts for their survival.
South Africa is a long-standing Party to the International Agreement on the Conservation of Albatrosses and Petrels (ACAP). The agreement was brought into existence on 1 February 2004. The day also falls on the date of the signing of the Agreement 22 years ago. ACAP has chosen the theme “Plastic Pollution” to mark the fourth World Albatross Day, to be celebrated on 19 June 2023. This follows the inaugural theme “Eradicating Island Pests” in 2020, “Ensuring Albatross-friendly Fisheries” in 2021, and “Climate Change” last year in 2022.
Multiple species of albatross are found across the Southern Ocean. This includes Antarctic, sub-Antarctic and subtropical waters. These albatrosses breed on sub-Antarctic and Antarctic islands including South Africa’s sub-Antarctic Marion Island. Marion Island holds significant breeding populations of four albatross species – the Wandering Diomedea exulans, Grey-headed, Light-mantled Phoebetria palpebrata and Sooty Phoebetria fusca. In addition to this, two other species of albatrosses have been seen ashore on Marion Island – Black-browed and Indian Yellow-nosed Thalassarchecarteri. To read more about the “other” two species of albatrosses recorded from Marion Island as uncovered by one of our researchers Kim Stevens, click here.
The Challenges Facing Albatrosses
Albatrosses face a range of challenges that threaten their survival. One of the most pressing issues is longline fishing, where albatrosses can become accidentally caught on fishing hooks, leading to injury or death. Pollution, habitat destruction, climate change, and invasive species on breeding islands also pose significant risks to their populations. World Albatross Day sheds light on these challenges and promotes measures to mitigate their impact. The pressing threats to Albatrosses in the Southern Ocean include invasive species on breeding islands, most notably, the house mice on Marion Island. Introduced to Marion Island by sealers in the early 19th century, the house mice have been inflicting devastating impacts on the ecology of the island, including killing its native seabirds.
Conservation Efforts and Awareness
The Mouse-Free Marion Project is a registered non-profit company in South Africa, established to eradicate the invasive albatross-killing mice on Marion Island. The project was initiated by BirdLife South Africa and the South African Department of Forestry, Fisheries and the Environment (DFFE). Upon successful completion, the project will restore the critical breeding habitat of over two million seabirds, many globally threatened, and improve the island’s resilience to a warming climate. For more information or to support the project please visit mousefreemarion.org.

Our aim is two fold: 1) we fill identified scientific gaps at the bird level that are crucial for best planning of the mouse eradication and development of appropriate mitigation measures. We are mostly focusing on three species of avian scavengers: Black-faced Sheathbill, Kelp Gull and Brown Skua and some of their prey. 2) we propose to use the three scavengers as indicators of recovery of the terrestrial ecosystem post-eradication by establishing baselines for the scavenger guild and their prey against which the impact of a successful mouse eradication can be measured in years to come.
More about the FitzPatrick long-term monitoring project:
The FitzPatrick long-term monitoring of Wandering and Grey-headed albatrosses and Northern Giant Petrel started in the early 1980s and has continued ever since. This individual-based monitoring of threatened species allows us to study the threats they face at sea (e.g. fisheries) and on land (e.g. mice) in order to act and decrease these threats and improve the conservation status. The species’ long-term monitoring is crucial as it allows us to decipher abnormal years from long-term trends.
More about the fieldwork:
The two projects above involve for example extensive counts of birds, lots of hiking, observations of bird behavior and record keeping of the activity of known individuals year after year.
What are your plans for this takeover:
During the takeover, we will be debriefing the year of Lucy Smyth who has worked on the island for our projects since April 2022. We will also train Chris and Michelle for the year ahead in all aspects, from field work to data entry and back-ups.
