It is with great sadness that we announce the untimely passing of Dr Precious Thembumuzi Mahlalela.
Dr Mahlalela, Research Coordinator of the South African Polar Research Infrastructure (SAPRI) LTO-Ocean Integrated Facility, passed away on 28 November 2023 after a short battle with cancer.
Dr Mahlalela joined NRF-SAEON (host of SAPRI) in May 2023 at the same time as successfully finishing off the corrections for her PhD in Ocean and Atmospheric Sciences thesis, entitled Variability and Trends in Rainy Season Characteristics of the Eastern Cape. She was due to graduate in December.
Upon joining the SAPRI team, she threw herself straight into the adventure, assisting with SEAmester and providing great support at sea. As soon as she was back on dry land she flew to China to learn about moorings. Although this was her first international trip, she approached it like the other challenges she has faced, with a calm and humble attitude, open to learning and new experiences. Upon her return, she insisted on accompanying the SEAON team on a science engagement roadshow in the Western Cape to inspire young minds. She continued to work with the same positive energy and gentle sense of humour that endeared her to everyone.

“In the short time she was with us at SAPRI she became part of our family. Taken from us far too soon, her light will continue to shine through the friendships she made, the individuals she worked with, and the souls she ignited with inspiration. Fair winds and following seas, shipmate. We have the watch now” Prof Juliet Hermes – SAPRI and SAEON Egagasini Manager.
Your warmth and gentle spirit shone so brightly that any room you walked into lit up with a soft glow. You were an angel on this earth who combined both a bubbly and calming presence and we will miss you more than any words can convey. We were so honoured to have worked with you.
Go gently dearest Precious. With love, from the SAPRI team.
The SAPRI team and SAEON Egagasini team will miss you dearly.
Our deepest condolences to Precious’s family, friends and everyone who had the privilege of meeting her.

The National Research Foundation (NRF) supports and promotes research and human capital development through funding, the provision of National Research Facilities and science outreach platforms and programmes to the broader community in all fields of science and technology, including natural sciences, engineering, social sciences and humanities.
The South African Environmental Observation Network (SAEON) is a research platform funded by the Department of Science and Innovation (DSI) and managed by the National Research Foundation (NRF) since 2002. SAEON is mandated to observe and research ecosystems on land, in coastal regions and the oceans to understand how those systems function and might change over time and space when influenced by socio-economic driving forces including climate change. We deliver our data online and offer tools, services and advice for informed environmental policy-making.
SAEON Egagasini Node, based in Cape Town, Western Cape, requires the services of suitably qualified individuals to be responsible for collecting field data on birds and mammals, to be used for conservation and academic purposes as part of the South African Polar Research Infrastructure (SAPRI). The birder will be contributing to the project ‘On-island impacts of climate change on the Southern Ocean’s iconic seabirds’ run by the FitzPatrick Institute (University of Cape Town).

The South African Weather Service (SAWS) has been part of the South African National Antarctic Programme (SANAP) from the beginning, when the first team was appointed to stay on Gough Island. The metkassies (meteorological overwintering team members) continue to contribute to a long history of data collection on Gough Island. This includes an automatic weather station that measures temperature, wind speed and direction, humidity, and pressure.
What can the new overwintering team on the island look forward to?
The metkassies when on shift do visual observations which includes cloud height and type, horizontal visibility, precipitation type, weather present and past and sea temperature. Formal observation is done every hour from 06:00GMT until 15:00GMT and then every 3 hours during night shift. This is done every day of the week.

Research team on the recent Gough Island takeover expedition.
Phytoplankton are microscopic plants that live in the ocean, and just like plants on land they need to have enough food to grow and be happy. However, some places in the ocean don’t have enough food for them whereas some places do. The Southern Ocean Carbon & Climate Observatory (SOCCO) team based at CSIR, Trace Metals team based at Stellenbosch University (TracEx) and the Department of Forestry, Fisheries and the Environment: Oceans and Coasts team are trying to figure out where those places are (in the Southern Ocean).
During the Gough Island takeover expedition:
The Trace Metal Biogeochemistry research teams sampled upstream and downstream of Gough Island to look at how the Antarctic Circumpolar Current (ACC) interacts with the island to resuspend sediments from the seafloor. This resuspended sediments acts as a source of trace metals to the surface mixed layer in support of phytoplankton blooms. The team used a 12 bottle mini-CTD rosette system (see image below, right) to sample for dissolved trace metals, particulate trace metals and organic trace metal chemistry.

Trace Metal Biogeochemistry
Seasonal Iron speciation in the Southern Ocean, from open ocean environments to naturally fertilized sub-Antarctic Islands (Marion and Gough Island)
Including all ship-based scientists sampling for trace metals
The project in more detail:
The Southern Ocean (SO) is one of the largest high-nutrient low-chlorophyll regions in the World’s Ocean, where primary productivity is limited by iron bioavailability, thereby impacting the strength and efficiency of biological carbon pump. There are, however, exceptions with large phytoplankton blooms persistently observed downstream of the sub-Antarctic Islands. While extensive research has focussed on iron-biogeochemistry around Kerguelen and Crozet islands, no such studies have been conducted at Marion and Gough islands.
Furthermore, whilst our previous studies have made substantial advances toward addressing the gaps in seasonal data coverage through the Southern oCean seAsonaL Experiment (SCALE) 2019 winter and spring expeditions, there is still a paucity of dissolved iron data in the SO, especially from autumn to late spring. This is severely hampering our understanding of the full seasonal biogeochemical iron cycle and its impact on primary production. This project aims to continue its focus on seasonality by expanding seasonal coverage of iron measurements to include autumn (Marion) and late-spring (Gough) expeditions for more comprehensive coverage of the SO seasonal cycle, with a particular focus on quantifying biogeochemical cycling of iron-pool around these understudied islands.
