Developing AI and digital infrastructure for digital twinning of the polar regions

Digital Twinning is next generation technology for data fusion and computer modelling enabling us to rapidly get answers to “what-if” questions. DTs are already in operation in industry and involve highly interoperable data pipelines, optimisation, and a mixture of knowledge-informed and data-driven probabilistic machine learning and artificial intelligence (AI). DTs are increasingly becoming a key component for research discovery, education, and aiding discussions at the board-level without having to wait weeks to months for results from traditional computer models.

BAS scientists and engineers are developing Digital Twins of the Antarctic and Arctic natural environments, polar research bases, our research ship and automated vehicles, and operational planning. By collaborating with a wide range of international research institutes and businesses our aim is to support international efforts to develop a Digital Twin Earth.

IceNet: Sea ice forecasting

IceNet is a probabilistic, deep learning sea ice forecasting system developed by an international team and led by British Antarctic Survey and The Alan Turing Institute [Andersson et al., 2021]. IceNet has been trained on climate simulations and observational data to forecast the next 6 months of monthly-averaged sea ice concentration maps. IceNet advances the range of accurate sea ice forecasts, outperforming a state-of-the-art dynamical model in seasonal forecasts of summer sea ice, particularly for extreme sea ice events. This step-change in sea ice forecasting ability brings us closer to conservation tools that mitigate risks associated with rapid sea ice loss.

Automated route planning for vehicles

The RRS Sir David Attenborough (SDA) provides an opportunity to revolutionise ship management using Artificial Intelligence. The SDA Digital Twin project will develop and integrate AI algorithms that exploit the diverse range of available environmental datasets and forecasts to develop a real time polar route-planning toolkit that can be used by the Captain for route-planning decision support on the bridge. These planned routes will be displayed via digital dashboards that enable proposed courses and parameter settings to be visualised in tandem with existing information services on the bridge.

Icesheet model emulation

We are developing a new approach to emulate the output of a process-based ice sheet model trained on a set of pre-computed ice sheet simulation runs. The aim of the emulator is to mimic how the process-based simulator would have responded, massively reducing computational cost. This allows the exploration of a much bigger range of environmental scenarios than would be possible using the simulator alone and, crucially, will enable probabilistic predictions of the ice sheet state, and sea level contribution, to be produced in an instantaneous manner.



Earth observation: automated object detection and tracking

Accurate measurements of sea ice extent, its concentration, and iceberg position are important for safe navigation of ships, maintaining fisheries and understanding ecosystem dynamics. These features have primarily been detected using microwave data; however the coarse, 6.25 km, spatial resolution of this microwave data precludes its use in decision-making tasks. Recent increases in the spatial coverage and temporal resolution of 40 m resolution Synthetic Aperture Radar (SAR) imagery, is opening new opportunities to rapidly detect ice sheet and iceberg position with greater positional accuracy. Our team are developing supervised and unsupervised machine learning techniques to automatically detect sea ice and iceberg position from Sentinel-1 SAR imagery.
