Future of ocean sciences for sustainable Earth: Observations from OceanObs’19

The Ocean Observations Conference (OceanObs) meets once in a decade to discuss the future and development needs of ocean science. At OceanObs’19, 149 Community White Papers highlighted the complexity of ocean observations, and especially the need for integrated, coherent and distributed approach, considering the processes under study that varies from very small to broad areas, and from very short to long time scales. Technical developments steers marine environment observations towards more integrated and holistic way but there are also challenges in the horizon.

Members of the ICOS community have contributed to the OceanObs’19 conference in many ways, for example by publishing a scientific article which describes the ICOS ocean network’s role in monitoring sea surface carbon dioxide uptake. ICOS was mentioned in several presentations and it was also visible at the vendor area: the ICOS Ocean Thematic Centre has partnered with the Saildrone company to validate the data from the fixed ICOS ocean stations in the Mediterranean Sea and the Atlantic Ocean.

The conference offered some shocking numbers on heat storage of the oceans. Out of the excess heat that the Earth has accumulated since 1971, 90 percent is stored in the oceans, compared to 1 percent stored in the atmosphere (Sabra et al. 2016). However, the course of the future actions seems to be less clear than the shocking numbers. If only as little as 15% of the sea floor has been mapped so far (i.e. Wölfl et al. 2019), should the efforts be put into more detailed sea bed mapping? More detailed mapping can be easily justified due to increased safety in navigation and knowledge of biology and geophysics. Yet, it would also reveal the natural resources at the oceans and hence facilitate the exploitation of minerals and other resources from the sea floor. This would cause more disturbance to ocean ecosystems and really rock our boat, the Ecosystem Earth.


We need open access to data as well as better synergies and integration among research infrastructures and other organisations, in order to understand oceans more deeply. The OceanObs conference and the complexity of ocean sciences are relevant to the United Nations (UN) initiative ‘UN Decade of Ocean Science for Sustainable Development’ (2021− 2030) to achieve its’ goal: the ocean we need for the future we want! The initiative supports the UN member states to achieve the Sustainable Development Goals by 2030, by providing science-based solutions, catalysing major investments in ocean science, stimulating national and regional linkage as well as the sustainability of Global Ocean Observing System.

ICOS data generates scientific knowledge which advances the fulfilment of the United Nations’ Sustainable Development Goals, such as ‘Climate action’ and ‘Life below water’. ICOS is a distributed research infrastructure which supports the increase of the data interoperability and aims to set an example for new projects in improving the overall governance of ocean observations. We offer free and integrated data on oceanic greenhouse gases: for example, data sets from M/S Nuka Arctica and G.O. Sars are openly available and used by scientists and policy-makers to mitigate to the climate change.

The next OceanObs’29 will be organised in Qindao, China. I truly hope that by then, we have not lost our momentum and climate change mitigation has not been turned into climate change adaptation. For the future we want we need healthy oceans, and for that, we need science.
