In the western Antarctic Peninsula region, micronutrient injection facilitates strong plankton blooms that support productive food webs, unlike large areas of the low-productivity Southern Ocean.We use naturally occurring radioisotopes of radium to constrain rates of chemical fluxes into Ryder Bay (...
