Advance in Marine Autonomy for Southern Ocean Observations
Andreas Marouchos, Hui Sheng Lim, Pat Lewis & Christopher Moony
Autonomous technologies, such as autonomous surface vehicles (ASVs) and autonomous underwater vehicles (AUVs), offer the potential to substantially increase the scale of future marine observations in the Southern Ocean. Autonomous technologies can be a force multiplier for marine observation, collecting ocean data over extensive spatial and temporal scales while requiring fewer human operators. Given the cost of operating ship-based research platforms in the Southern Ocean, autonomous systems can provide a cost-effective means of rapidly scaling observation systems over a broad geographical area. Autonomy promises to deliver greater manoeuvrability, longer endurance and reduced operational risks, which can address the critical challenges of localisation, persistence and scale faced by the existing Southern Ocean observation methods. The use of autonomous systems for marine observations offers new perspectives to generate a greater understanding of the Southern Ocean.
To fully leverage the potential of marine autonomy in Southern Ocean observations, autonomous systems require innovations in mission planning and data collection strategies, as well as improvement in polar navigation capabilities, sensor data fusion, and integration with the emerging Internet of Things (IoT) technology. This session aims to gather works that address the most recent advances and applications of operations and technology in marine autonomy for enhancing data collection and observation of the Southern Ocean.
Automated Southern Ocean Sensor Webs

Understanding how the ocean shapes the chemistry and biology of our planet is a fundamental challenge facing humanity. This is especially true for the Southern Ocean which plays a disproportionately important role relative to its size on the planet’s carbon biogeochemistry. A range of mature automated technologies is now providing the possibility of deploying a Southern Ocean network that is collected unprecedented data. This session will explore new science findings provided by BGC-Argo profiling floats, glider and surface vehicles. These technologies are providing data enabling the development of modeling approaches to provide a synthetic framework for better understanding the trajectory of the Southern Ocean. We are seeking contributions that highlight novel science findings, new automated technologies, sensors, models, state estimations and ideas for the future distributed network development.
Promoting alternative, low-cost, solutons for Southern Ocean observing

A major challenge in observing the polar regions is access to the equipment and expertise needed to properly observe, qualify, and distribute data. These problems are often exacerbated by the lack of standard operating procedures or best practices, as well as the widespread belief that high-end equipment and facilities are necessary.
In a context where our scientific communities are questioning their resource consumption and the environmental impacts associated with their new technological developments, and at a time when the 6th IPCC report calls for a drastic reduction of the human impact on the environment; this session proposes:
- to offer an overview of initiatives designing or promoting approaches that are better sized for their use, more robust, more sustainable and more economical in energy, raw materials and finances.
- to discuss the conditions where it becomes possible to reconcile sobriety and efficiency of measurement.
Better autonomy, greater resilience, but also a reduced cost or simplicity of use are all arguments in favor of the deployment of these new sensors in the complex and difficult to access environment of the Southern Ocean. Having such equipment and standardized methods available to scientists on sub-Antarctic islands and ships of opportunity will become a strong asset to address many scientific and applied research challenges in the Southern Ocean.
To address these considerations, a task force has been established under the IODE/IOC/GOOS Ocean Best Practices framework. This Task Team will identify common and accepted best practices already in use within the community for the observation of physical, chemical and biological parameters of the coastal ocean that will be applicable to the Southern Ocean. The identification of these practices will result in a best practices manual for observations and a set of measurements that are affordable, easily transportable, easy to use, and widely applicable.
