Abstract:This study introduces an ocean-based carbon dioxide removal (CDR)
approach: Nearshore Macroalgae Aquaculture for Carbon Sequestration
(N-MACS). By cultivating macroalgae in nearshore ocean surface areas,
N-MACS aims to sequester CO2 with subsequent carbon storage. Utilizing
an Earth System Model with intermediate complexity (EMIC), we explore
the CDR potential of N-MACS alongside its impacts on the global carbon
cycle, marine biogeochemistry and marine ecosystems. Our investigations
unveil that coastal N-MACS … Show more
