Nutrient and temperature controls on modern carbonate production: An example from the Gulf of California, Mexico

In addition to salinity and temperature, nutrient concentrations in surface waters are known to have a significant impact on distribution of carbonate-producing biota, but have never been quantitatively evaluated against different temperatures along a latitudinal transect. The western coast of the G...

The western coast of the Gulf of California, Mexico, presents a natural laboratory for investigating the influence of oceanographic parameters such as salinity, temperature, and chlorophyll a, a proxy for nutrients, on the composition of a range of modern heterozoan and photozoan carbonate environments along a north-south latitudinal gradient spanning the entire warm-temperate realm (29°N–23°N).

Salinity, in contrast, fluctuates little and remains at an average of 35‰. From south to north, carbonate production ranges from oligotrophic-mesotrophic, coral reef–dominated shallow-water areas (minimum temperature 18.6°C) through mesotrophic-eutrophic, red algal–dominated, inner-shelf carbonate production in the central gulf (minimum temperature 16°C), and to molluscan-bryozoan, eutrophic inner- to outer-shelf environments (minimum temperature 13.7°C). The Gulf of California data, supplemented with oceanographic and compositional information from a database compiled from a spectrum of modern carbonate systems worldwide, demonstrates the significance of nutrient control in the formation of heterozoan, photozoan, and transitional heterozoan-photozoan carbonate systems and serves as a basis for more accurately interpreting fossil carbonates.Instituto Politécnico Nacional (IPN).
