The All-Atlantic Ocean Research Alliance 2022 Forum was co-hosted by the United States and Brazil, in collaboration with the European Commission, over two events between May and July 2022. Outcomes from the Scientific Event in May were highlighted at the Ministerial Event in Washington, D.C. July 12-14, which featured ministerial interventions and the signing of the All-Atlantic Ocean Research & Innovation Alliance Declaration. The Declaration outlines the vision of the All-Atlantic and will build upon collaboration between existing initiatives in the Atlantic Ocean on ocean research and innovation.
During a side event “Research Cooperation from Pole to Pole” hosted at the residence of the Portuguese Ambassador in the USA, Washington, DC. Dr Juliet Hermes, Acting Manager of SAPRI hosted at the South African Environmental Observation Network (SAEON) Egagasini node and Dr Tamaryn Morris, Senior Marine Scientist at South African Weather Service attended this meeting on 12 July.
Introduction to the Southern Ocean/Antarctic Research interests of the All-Atlantic partners from the United States, Europe, Brazil and Canada. Dr Tamaryn Morris gave an introduction of South Africa research interests.
A panel discussion on challenges and best practices for All-Atlantic cooperation and preparation of recommendations and next steps to facilitate an All-Atlantic cooperation in Polar research was chaired by Evan Bloom. Dr Juliet Hermes was one of the panelists. A summary of recommendations was done afterward.
Juliet Hermes: ” The panel raised some very pertinent questions around polar infrastructure. It was interesting to hear those other countries struggle with the same issues as us and the need for shared best practices was highlighted.
The meeting was a great networking opportunity and SAPRI has been invited to collaborate on the next major European funding call. We also had the opportunity to contribute to key messages for the ministers.”
Juliet and Tammy did make time to take a picture while in Washington.

Contemporary and Future Drivers of CO2 and Heat in the Southern Ocean
The contemporary Southern Ocean mitigates the effects of anthropogenic climate change through its disproportional uptake of carbon and heat. However, it is not well understood how this role will evolve under different emission and mitigation scenarios. The Southern Ocean also remains the largest source of global ocean uncertainty in the global estimates of CO2 and heat fluxes. While much has been achieved globally and regionally in constraining the variability and some of the mechanisms that drive Southern Ocean CO2 and heat fluxes separately, we propose that a significant part of the challenge lies in the lack of research on CO2 and heat together to better understand the feedback and the mechanisms that drive those feedbacks.
This SANAP-NRF project aims to examine the changing role of the Southern Ocean in global climate by looking at the two main drivers CO2 and heat, in an integrated way using an unprecedented 10-year high resolution glider dataset from the 2012-2022 SOSCEx experiments, prognostic biogeochemical models, and new observational experiments planned in partnership with CSIR and DFFE as well as the SO-CHIC EU H2020 project. This collaboration is undertaken as part of the emerging National Ocean CO2 Facility, a research infrastructure integration between CSIR and DFFE within SAPRI and hosted at DFFE.
We aim to gain a better understanding of how the interaction of atmospheric synoptic cycles (storms) and fine-scale (0.1-100 km) ocean processes influence seasonal-decadal variability of CO2 and heat fluxes. This will include the extent to which they feedback on each other and ultimately contribute to a better understanding of the role of the Southern Ocean in the global carbon-climate system.
The expected three outcomes are:
- Improved observational constraints for the contemporary seasonal-interannual variability of CO2 and heat fluxes.
- Understanding of how storms and their interaction with fine-scale dynamics influence the seasonal and interannual variability of CO2 and heat fluxes.
- Identify the potential mechanisms that could explain the decadal anomaly in CO2 fluxes at the end of the 20th century.
Winter cruise sampling:
The SCALE Winter-2022 cruise provides an important opportunity to address a key source of uncertainty in annual Southern Ocean CO2 and heat observations – the dearth of winter time observations. While the lack of winter observations has been improved by the recent proliferation of SOCCOM floats, ship-based observations remain highly valuable as an independent and direct measurement of CO2 and importantly include heat flux observations. On the SCALE Winter-2022 cruise, the CO2-Heat team will be sampling profiles of dissolved inorganic carbon (DIC) and Total Alkalinity. The underway pCO2 system will also be operated during the cruise. Simultaneously, the heat flux sensors are in continuous operation measuring the short and long-wave radiation on minute time-scales. In addition, as part of SO-CHIC, two Saildrones will overlap with the ship sampling path for calibration of measured CO2 and heat flux. The Saildrones will remain in the Southern Ocean sampling heat and CO2 fluxes for the remainder of winter. These key winter observations will be contrasted to the previous summer observations made during the dedicated SO-CHIC cruise in January 2022.

BUOYS: More about the project and the team:
A variety of synoptic, seasonal and interannual drivers influence the forms, types and concentration of sea ice in the Marginal Ice Zone (MIZ) in the Southern Ocean. The temporal and spatial distribution of the ice and its physical, mechanical and biological properties are directly related to the natural variability of the oceans and atmosphere, but also anthropogenic climate change. Climate and Earth System Models have limited sea ice variable parameterisations due to the scarcity of spatially distributed high resolution measurements from the region, specifically during winter/spring. To better understand atmosphere-ice-ocean MIZ processes and to improve future prediction of seasonal sea ice coverage and extent, three main approaches are available: (1) in situ measurements, (2) area-wide satellite data, and (3) numerical and experimental modelling. The meaningful connection of these is essential for enhancing understanding of this region.
Improved use of technology and autonomous devices, capable of persistent in situ sampling at finer spatial resolutions over the winter/spring seasons in the Antarctic MIZ, are key to obtaining the datasets needed to improve Earth System Models and to validate remote-sensing products. This requires a multidisciplinary approach including engineering, oceanography and climate science. The #SCALEwin22 expedition BUOY team comprises researchers and students from several institutes including the University of Cape Town (Robyn, Michael, Justin, Lawrence, Agoritsa and Francesca), Nelson Mandela University (Jacques), University of Melbourne (Guilio and Ippolita), University of East Anglia (Alberto) and the Finnish Meteorological Institute – FMI (Jan-Victor). During the expedition we aim to collect high-frequency wave and ice drift data using ice-tethered buoys (see images below) designed and built by the UCT team as well as open water buoys developed by Tallinn University of Technology and WiseParker OÜ. These measurements will be complimented by advanced ship-based imaging of ice floes and waves using LiDAR, stereo and thermal cameras. These unique high resolution data sets will be used to better characterise wave drivers of sea ice formation during winter and to inform Southern Hemisphere climate predictability.
