title: ColaltedDatasets for Figures 2, 3, and 4 of: "Marine carbonate accumulation – A (re-)vision of present estimates and future declines"

description: This dataset contains collated freely available datasets used to generate Figures 2, 3, and 4 in the submitted manuscript "Marine carbonate accumulation – A (re-)vision of present estimates and future declines". The data is uploaded in this repository to make it easily available for researchers without the need to "hunt down" individual data sources again. All datasets are best viewed with Ocean Data View (https://odv.awi.de/). Figure 2 shows the most recent modern-day distribution of surface water omega values for calcite and aragonite.

For visualization, the original dataset was cleaned and transferred into Ocean Data View (https://odv.awi.de/).
