Coastal Upwelling 1. Pigment concentrations reflect the amount of plants in the water and are a measure of biological productivity in the ocean. Primary productivity is the growth of plants and secondary productivity is the growth of animals, which make up the higher levels of the food chain, and which depend on the primary production of plants. Chlorophyll pigment, and also water temperature, can be measured by satellites orbiting the earth.
False color is added to highlight different concentration values and different ocean temperatures.
Explain the distribution of pigment concentrations and temperatures along the California coast, in light of what you have learned about upwelling currents .
