South African Polar Research Infrastructure (SAPRI): Launch of the Preparatory Phase
The SAPRI team is pleased to inform you that the contractual agreement for the starting of the SAPRI implementation phase is being finalized between the Department of Science and Innovation (DSI) and National Research Foundation of South Africa (NRF). We have now entered the Preparatory Phase of SAPRI’s operationalisation and interim measures are being put in place to ensure progress is made. Until the formal signature of the contract, the SAPRI cannot officially initiate Phase 1, but in the interim the Preparatory Phase will continue the conceptual design of the RI and predispose priority actions with the support of the community.
These achievements would not have been possible without the trust demonstrated by the scientific SANAP community towards the SAPRI team, the contribution and constructive support of the DFFE Oceans & Coasts Branch managing the SANAP logistics, and the commitment to collaborate offered by other institutions that have historically been involved in polar research. This gestation and birth of SAPRI is a major advancement to streamline, consolidate and grow the South African polar sciences, and represent a systemic innovation to maximize the investments of the various governmental institutions involved. The SAPRI will officially start from the advantageous position of being incubated within South African Environmental Observation Network (SAEON), which will fast-track the establishment of the governance and of the consortium agreements.
The launch of the SAPRI Preparatory Phase was announced via a webinar and a Q&A session to illustrate the main aspects of SAPRI, its organization into integrated facilities, and the first steps of the implementation phase listed in the business plan. To accelerate the implementation phase, it is proposed to initiate an informal Preparatory Phase of SAPRI and to discuss the following actions with the community of stakeholders:
- Establishment of the User Fora overseeing the requirements of the integrated facilities.
- Implementation of the Task Team for the reorganization of SANAP within the NRF.
- Consultation and discussion on the implementation steps for the Polar Science Transformation Plan.
- Establishment of the DFFE-SAPRI Task Team for assisting with science-related logistics. This will include discussions around the SA Agulhas II dry dock scheduled for November 2021.
The virtual webinar took place on 29th September 13:00-15:00 and was led by the SAPRI team; Tamaryn Morris, Marcello Vichi, Juliet Hermes, Johannes Pauw.

Ecosystem processes are changing worldwide, especially with the impacts of invasive species being exacerbated by climate change. This is particularly obvious in the Southern Ocean where a warmer and dryer environment allows the proliferation of species once limited by the cold climate. South African Special Nature Reserve, Marion Island is no exception. A recent proliferation of invasive House Mouse attacks on endangered breeding seabirds suggests a profound alteration of the natural ecosystem. This has led to the planned eradication of mice at Marion Island in winter 2023.
For the next three years, the new SANAP project co-led by Dr Maëlle Connan (Research Fellow in the Marine Apex Predator Research Unit, Nelson Mandela University) and Prof. Peter Ryan (director of the FitzPatrick Institute of African Ornithology – University of Cape Town) will focus on three data deficient species of avian scavengers: Black-faced Sheathbill, Kelp Gull and Brown Skua.
By focusing on these three species and some of their prey, the project intends first to fill identified scientific gaps that are crucial for best planning of the mouse eradication. Second, these three scavengers will be used 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. (Above: Left – Maelle Connan, Right – Peter Ryan)

An important aspect of the project will entail conducting regular censuses and seasonal round island counts in addition to behavioural observations of the focal scavenger species. Indeed, the three species to be studied are at the top of the terrestrial food chain, and thus can be used as indicators of recovery of the island biota post-eradication.
On one hand, Black-faced Sheathbills and Kelp Gulls used to predate on terrestrial invertebrates, at least seasonally, but this behaviour has decreased in sheathbills as invertebrate populations have collapsed through mouse predation. There are no recent data for Kelp Gulls. On the other hand, many pairs of Brown Skuas predate mainly on burrowing petrels, thus will inform on the recovery of these nocturnal species from mouse predation. The skua data will be complemented by the implementation of an automated acoustic monitoring to detect the presence and coarse distribution of the most elusive and cryptic nocturnal species which are notoriously difficult to study. (Left – Eleanor Weideman in the field on Marion Island.)
Data obtained during the project will be swiftly shared to the Mouse-Free Marion programme manager Dr Anton Wolfaardt, to ensure updated information is available for the best planning of the mouse eradication.

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.
