Assessing the global ocean science community: understanding international collaboration, concerns and the current state of ocean basin research

Web of Science data covering 2000–2020 was used to analyse trends in ocean research, specific to the five ocean basins (Arctic, Atlantic, Indian, Pacific, Southern), to investigate its state and any underlying concerns for addressing UN Decade of Ocean Science goals and UN Sustainable Development Goal 14 "Life Below Water". Though Atlantic research has dominated, Pacific research is nearing parity with its neighbour due to significant output growth by China and is soon likely to become the most researched basin. International collaboration, built around G7 countries and China, has increased by 10 percentage points since 2000 but research remains mainly domestic. Outside these countries, there has been growth in collaborations involving Small Island Developing States and a doubling of South America's global share of ocean basin papers. However, sub-Saharan African research output has not mirrored this expansion. Further growth could be catalysed by increased support for educational efforts and infrastructure development, particularly given the highly specialised and institutionally driven nature of ocean basin research.
