  1. Summary of the POC budget in the eddy core (first two rows) and in the eddy core below 1027.05 kg/m3 isopycnal (≲320 m; third row). In the last two rows, the budget is calculated by using the POC from the extended size spectrum as well. Please note that each value is obtained from the average of all the isopycnal bins composing the eddy core (which were 46 m deep, on average; “ BGC Argo data”). The asterisk, when present, indicates that the metric is significantly different from zero (t-test; note that the t-test was carried out only for metrics reported in bold). PARR stands for particle-associated respiration rate.
