Accompanying code to the paper "Sea-ice impacts inter-annual variability of phytoplankton bloom characteristics and carbon export in the Weddell Sea". Abstract: The Antarctic Marginal Ice Zone (MIZ) accounts for 15\% of the Southern Ocean’s primary production, but limited data has hindered understanding of its variability and connection to carbon export. Using a combination of gliders, biogeochemical Argo floats and satellite observations in the northeast Weddell Sea, we show that years with more sea-ice formation over winter are followed by more intense phytoplankton blooms (~15% greater daily Primary Production) and export to 100 m (~50% higher daily carbon export) the following summer. However, the carbon export beyond the deepest winter mixed layer did not vary in proportion to primary production, suggesting different drivers of carbon export at depth compared to surface waters. Furthermore, across the entire MIZ, the response of blooms to sea-ice volume was spatially variable, indicating the need to ...
