Mean (± standard deviation) values of sea surface temperature (°C, Temp.), nitrate concentration at the base of the euphotic layer (NO3 [1%PAR], µmol L−1), density difference between the surface and the base of the euphotic layer (Δσt, kg m−3), euphotic layer depth (1%PARz, m), and upper mixed layer depth (UMLz, m) for each location. For the regions where the resource supply index was calculated, the mean values of NO3 [1%PAR] divided by Δσt and 1%PARz divided by UMLz are also given. n is the number of measurements conducted at each location. Nitrate concentration data for the Soiree study correspond to 40 m depth [31].
