Mechanisms driving biological CO2 drawdown in the Subarctic Pacific unraveled
Nishioka and co-authors compiled comprehensive data sets of iron and macronutrients covering the whole subarctic Pacific…
Macronutrients
Enlighten why macro and micronutrients display different remineralization length scales
Boyd and co-workers (2017, see reference below) explore the abiotic and biotic mechanisms that underpin internal metal cycling. Although they are focusing on iron (Fe) as the best-characterized metal, they […]
Submarine Groundwater Discharge as a major source of nutrients in the Mediterranean Sea
The authors are proposing a radium-228 (228Ra) isotope mass balance for the upper Mediterranean Sea to estimate the magnitude of Submarine Groundwater Discharge (SGD) to this basin. Radium isotopes have […]
When atmospheric dynamic controls the nutrient distributions in the ocean
Rainfall detection with satellites together with high-resolution data (~0.3°) for dissolved iron (DFe), aluminium (DAl), and inorganic phosphorus (DIP), confirm the existence of a sharp north–south biogeochemical boundary in the […]
