摘要: Variation in ocean C: N: P of particulate organic matter (POM) has led to competing hypotheses for the underlying drivers. Each hypothesis predicts C: N: P equally well due to regional co-variance in environmental conditions and biodiversity. The Indian Ocean offers a unique positive temperature and nutrient supply relationship to test these hypotheses. Here we show how elemental concentrations and ratios vary over daily and regional scales. POM concentrations were lowest in the southern gyre, elevated across the equator, and peaked in …
