This dataset, resulting from Task 4.5 quantifies the potential of ocean-based negative emission technologies (NETs) using Earth System Models (ESMs). The dataset consists of simulations of ocean liming and direct CO2 removal from seawater. The ocean liming scenarios utilize excess CaO and cement production capacities from the EU, China, and the US, exploring their application for ocean alkalinization and gauging termination effects. Simulations ran from 2015-2100 using NorESM2-LM, EC-Earth3-CC, and AWI-CM models. This comprehensive dataset informs on the efficacy of ocean-based NETs and provides insights for future climate mitigation strategies, aligning with the Paris Agreement goals. It facilitates further analysis and supports ongoing research in global carbon cycle feedbacks of ocean-based NETs.
