Fig. 5: Geographical distribution of ORO research based on country of first author affiliation.

a The colour scale represents the relative importance placed on OROs compared to the wider ocean and climate literature. The size of the points in the centre of each country indicates the total number of ORO publications. b The colour scale indicates the slope of the inter-annual (1980–2022) trend in the number of ORO publications. A greater slope indicates annual ORO publications increased more over time compared to a slope closer to zero indicating the number of ORO publications remained stable. The slope is determined using a linear regression fit using generalised least squares with an AR1 temporal autocorrelation coefficient. ‘NS’ indicates that the trend was not significant, and ‘NA’ indicates that the model was not able to converge. c The relative importance of mitigation OROs in comparison to adaptation OROs (i.e. natural resilience and societal adaptation branches). This is expressed as the percent of all ORO publications that are mitigation OROs; thus 100% indicates all publications are mitigation OROs, 50% an equal partitioning, and 0% all adaptation OROs. d The links between the geographical region of first author affiliation (nodes on left-hand side) with where the research was conducted (nodes right-hand side, determined from geoparsing). The size of the grey shaded paths connecting the nodes indicates the size of the link.
