A new era of digitalisation for ocean sustainability?

As the United Nations Decade on Ocean Science for Sustainable Development begins, this paper explores recent and likely future digital technologies - especially in the field of ocean observation - that will contribute to ocean sustainability. It examines advances that could lead to substantial improvements in the data collection and analysis of the impact of climate change and human activity on marine ecosystems, while also contributing to the monitoring and reduction of the ecological footprint of ocean-related economic activity. The paper also provides preliminary reflections on how the COVID-19 pandemic might affect digitalisation in the ocean economy, and what strategies could help support ocean research and innovation during and after the crisis.
