Surface pH, satellite imagery and vertical models in the tropical ocean

The relationships between surface pH, ocean color and surface temperature are discussed conceptually. As an example, log pigment and sea-surface temperature (SST) obtained from color and IR satellite imagery collected over the Gulf of California (Mexico) in November 1981 are compared with in situ pH...

Description
Summary:The relationships between surface pH, ocean color and surface temperature are discussed conceptually. As an example, log pigment and sea-surface temperature (SST) obtained from color and IR satellite imagery collected over the Gulf of California (Mexico) in November 1981 are compared with in situ pH and temperature measurements made 3 weeks later. Plots of log pigment vs. SST and pH vs. in situ temperature show a characteristic break in slope, suggesting that the area studied may be divided into a high productivity northern section and a sourthern section of correspondingly lower productivity. A multidisciplinary (physical-chemical-biological), one-dimensional (vertical) model is used to produce characteristic shapes of log pigment vs. SST and pH vs. in situ temperature plots.
