Meltwater from Antarctic Giant Triggers South Atlantic Phytoplankton Bloom

A melting Antarctic iceberg, A-23A, released nutrient-rich meltwater as it drifted into warmer South Atlantic waters, fueling a large phytoplankton bloom detectable by NASA satellites (VIIRS on Suomi NPP and the PACE mission). Scientists say light conditions and nutrients from iceberg melt promote bloom formation, with implications for the marine food web and carbon cycling; the duration and full ecological impact remain under study.
