The first ocean session covered the Antarctic sea ice research field led by the Sea Ice Team from the Marine and Antarctic Research for Innovation and Sustainability (MARiS). The research themes covered in this session were innovation and development, oceans and marine eco-systems under global change and earth systems observations. The presentations and posters under these research theme covered a diverse range of projects from large-scale sea ice observations, tracking and measurements to the small-scale sea ice dynamics, properties and biogeochemistry. Antarctic sea ice research has received a comparatively limited focus compared to its Arctic counterpart. The MARiS sea ice team is constituted of the departments of Oceanography, Electrical and Chemical Engineering at the University of Cape Town, with projects aimed to contribute new insights and push the boundaries within this research domain. The presentation within this session were on a variety of earth system observations models, simulations of sea ice wave interactions, innovative tool development for lab-based experiments and field-based work investigating sea ice dynamics and properties and the ecological impacts of algae and their biogeochemical significance. The session under the MARS theme; Oceans and marine ecosystems under global change was chaired by Principal investigator Tokoloho Rampai and it included an overview of Maris by Robyn Verrinder. The session was done in round table fashion and included posters and oral presentations. Tokoloho concluded the session with a closing statement

The 2nd issue of The Wanderer by the Marion80 Overwintering team is now available online. It is a bumper issue with 64 pages to read and to enjoy the amazing photo’s taken by the team members.
During the 6th Symposium sessions were allocated to cross cutting disciplines and it led to great presentations and discussions. 
She told her story when she started within the SANAP program as an honors student in Botany. she highlight the importance that as researchers we need to communicate our work and create awareness for the science that we participate in.
Sarah Fawcett asked Anché to highlight the possibilities of 
Prof Isabelle Ansorge of UCT and PI of 
She outlined the strength of SEAmester is that it combines theoretical classroom learning with the application of this knowledge through ship-based, and more importantly, hands-on research through the Agulhas System Climate Array (ASCA) programme. During past voyages 241 students from 26 universities all over South Africa having participated in these cruises. The presentation showed how successful this programme has been, but also the challenges that have been faced. A few were showcased of what has become of some of the 
Isabelle’s presentation was followed by two SEAmester students. Themba Mbalati(above left) a SEAmester student gave a

The symposium started with a keynote lecture by Prof Jukka Tuhkuri of Aalto University, Finland on the expedition to find the shipwreck of the Endurance: “On March 5th, 2022 an international Endurance22 expedition located the wreck of Endurance, the lost vessel of Ernest Shackleton. The Endurance22 expedition was organized by the Falklands Maritime Heritage Trust and the expedition team was taken to the wreck site by S.A. Agulhas II, captain Knowledge Bengu and his crew. Jukka outlined and discussed the three goals of the expedition: to locate the wreck, to tell the story of Endurance to new generations, and to conduct scientific work. The science team onboard included scientists from Stellenbosch University and Aalto University. The Keynote lecture discusses, inter alia, who Shackleton was, how the Endurance was lost and found, and what was learned on the Weddell Sea Expedition” abstract supplied by Prof Tuhkuri.

A welcoming reception took place after the keynote lecture . This reception allowed members of the SANAP community (both old and new) to interact in an informal meet and greet for the first time since the last Symposium in 2018. The 2020 Symposium was cancelled due to the COVID-19 pandemic, and a decision was made to postpone the 2022 Symposium to allow the SANAP community to generate new data post-pandemic.
Afterwards a workshop was held by the Association for Polar Early Career Scientists of South Africa (APECSSA), and they reported back to the SANAP community n Day 3 of the symposium. (Right: Photo Credit: Anché Louw – SAPRI)
Prior to the commencement of the Symposium, a meeting of the members of the South African national committee for Scientific Committee on Antarctic Research (SCAR) took place chaired by Prof Bettine van Vuuren and was attend in person and online by members of the committee. Prof van Vuuren as chair of the national committee feedback on day 2 of the symposium.
