== Staff == The base is staffed and maintained year-round by a team of scientists and support personnel. Each overwintering team arrives during the summer expedition and take-over period aboard the research and logistics vessel S. A. Agulhas II, stays at the base through the austral winter and returns to South Africa at the end of the next summer season - an expedition of approximately 16 months. The summer expedition and re-supply team (excluding ship's crew) consists of 80–100 persons, and includes administrative staff, heavy vehicle operators, helicopter crew, maintenance staff, the new overwintering team and a large scientific contingent. During the brief summer (typically December/January to February/March) the base must be resupplied with food, equipment and fuel, all waste products must be removed for transport back to South Africa, the new overwintering team must receive on-site training, and scientific investigations which cannot be undertaken in the winter months (such as extended field-work) must be completed. The overwintering team remains at the base alone and isolated between the months of March and December. To be fully self-sufficient, the team typically consists of the following personnel:
An electronic engineer who doubles as communications technician, A mechanical engineer responsible for the base systems An electrical engineer who manages power generation and distribution Two diesel mechanics responsible for maintenance of the diesel generators, heavy vehicles and skidoos A meteorologist who performs both observations and forecasting A cosmic ray physicist/engineer responsible for various research projects A high frequency radar physicist/engineer responsible for the auroral radar projects A third scientist responsible for the International Polar Year projects and other installations A medical doctor An expedition leader is selected from the overwintering team prior to the departure of the expedition, and a deputy elected to serve in his place should the need arise. The expedition leader is responsible for administrative tasks and reports to the South African National Antarctic Programme headquarters in South Africa.
== Research ==
SANAE IV's reason for existence is to provide a permanent year-round base for scientists undertaking research projects under the auspices of SANAP. Investigations carried-out year-round are predominantly in the physical sciences, while the summer months allow research in more diverse fields such as oceanography, biology, geology and geomorphology. Recent projects have also focused on sources of renewable energy such as solar and particularly wind power generation. There is not currently any formal medical research being undertaken. Ongoing physical science research programs includes the Antarctic Magnetospheric and Ionospheric Ground-based Observation (AMIGO), Southern Hemisphere Auroral Radar Experiment (SHARE) and Super Dual Auroral Radar Network (SuperDARN), Antarctic Research on Cosmic Rays (ANOKS), very low frequency (VLF) radio research and various International Polar Year projects. Detailed information about the research projects may be found under the research section of the SANAP webpage
== 2025 assault incident == In March 2025, an incident at SANAE IV received attention in South African media following reports of alleged misconduct among members of the overwintering team. A group of nine researchers stationed at the remote Antarctic base, where personnel are typically isolated for extended periods, were involved in a dispute that escalated into a physical altercation. According to the South African government, the incident involved an assault following a disagreement over a work task that required a schedule change. Reports based on an internal email described "deeply disturbing behaviour", alleging that a team member had physically assaulted a colleague, made death threats, and created an "environment of fear". South Africa's Department of Forestry, Fisheries and the Environment (DFFE) confirmed that an assault had occurred and stated that a response plan was activated shortly after the incident was reported in February 2025. The department initiated mediation and psychological support measures, while the alleged perpretator was reported to have shown remorse, undergone further evaluation, and issued a formal apology to victims. Allegations of sexual harassment were investigated, while officials stated that reports of sexual assault were not substantiated. Due to SANAE IV's extreme isolation located more than 4,000 km from mainland South Africa and largely inaccessible during the winter months no evacuation was undertaken, although an "emergency medical evacuation to a neighboring German base" was possible if such a circumstance occurred, and sources within the Antarctic research community suggested that South Africa has access to ice-capable ships and aircraft if an evacuation is deemed necessary. The situation continued to be monitored by government officials. Former SANAE IV overwinterer Lodrick Hlungwane described the psychological strain of the environment, stating that "It's a very challenging place. If you isolate yourself, you're bound to lose it", and noted that some individuals struggle to adapt, becoming withdrawn or prone to conflict under prolonged isolation. The incident also attracted attention from researchers studying human behaviour in extreme environments as they pertain to long-duration space missions, namely future crewed missions to Mars, where similar psychological stressors would be present but with even fewer possibilities for evacuation or external intervention. While noting that violence in Antarctic bases is rare in modern times, psychologists familiar with Antarctic missions stated that the confinement, monotony, disrupted sleep cycles, and limited external stimuli of Antarctic overwintering can amplify interpersonal tensions and impair emotional regulation. This incident was used by psychologists as an example of how existing screening methods may not reliably predict how individuals will respond under prolonged isolation, and more advanced examinations may be necessary for astronauts on similarly isolating missions.
