Regional differences in modelled net production and shallow remineralization in the North Atlantic subtropical gyre
We used 5-yr concomitant data of tracer distribution\nfrom the BATS (Bermuda Time-series Study) and ESTOC\n(European Station for Time-Series in the Ocean, Canary\nIslands) sites to build a 1-D tracer model conservation\nincluding horizontal advection, and then compute net production\nand shallow rem...
