Becker notes that correlation does not imply causality, "but it is pretty nifty that we found two strong correlations, which both point to the same physically plausible mechanism: the primordial stuff gets picked up preferentially by the most buoyant thermochemical upwellings."
In the Gulf of California (GC) previous studies have shown that mesoscale structures such as fronts, upwelling, and eddies influence the larval fish distribution as well as the structure and diversity of their species assemblages (Danell-Jimenez et al., 2009; Contreras-Catala et al., 2012; Avendano-Ibarra et al., 2013).
The tests included 1,000 cases of real ocean features, including 472 upwellings, 119 cloudy upwellings, 180 wakes, 10 anticyclonic eddies, 40 cyclonic eddies and 180 misclassified regions.
Regional processes influencing the P distribution include seawater circulation, e.g., P influx by coastal upwellings, and the sedimentation rate.
