Spatiotemporal high-resolution mapping of biological production in the Southern Ocean
Abstract The Southern Ocean is considered to play an important role in the global biogeochemical cycles of carbon and nutrients. It is still unclear how biological production there impacts climate change owing to the remarkable gap between the current and the ideal state of research. Here, we propos...
