Description: Number of in situ measurements obtained from instruments carried aboard oceanographic research and merchant ships. This is of annual data distribution. The spatial and temporal coverage of silicate data in the Gulf of Mexico is not uniform. Most of the historical data were collected over the continental shelf near shallow intertidal areas (<200 m depth).

Description: Silicate at 10 m depths for winter, spring, summer, and fall show relatively large horizontal gradients due to the effects of surface biological uptake and dissolution, physical forcing (e.g., vertical stratification, upwelling of nutrient-rich water, and circulation), river nutrient inputs, and decomposition of labile organic matter.

Description: Deeper in the water column, silicate at 250 m for winter, spring, summer, and fall shows marked west-to-east zonal gradients reflecting advection of waters of different preformed concentrations entering the Gulf of Mexico between the Yucatan Peninsula, Cuba, and Florida.
