Nitrates - Climatological Mean

Scientifically quality-controlled historical in situ nitrates data in the World Ocean Database 2013 obtained by chemical methods were used to construct annual, seasonal, and monthly climatological distribution fields of nitrates at selected standard depth levels of the world ocean on a one-degree latitude-longitude grid. Most of the historical data were collected over the continental shelf near shallow intertidal areas (< 200 m depth). This map presents the seasonal climatological mean fields of nitrates for two water depths (10 meters and 250 meters) on a one degree grid. Measurements are in umol/l. Seasons are as follows: Fall (October - December), Winter (January - March), Spring (April - June), Summer (July - September).

Phosphate - Climatological Mean

Scientifically quality-controlled historical in situ phosphate data in the World Ocean Database 2013 obtained by chemical methods were used to construct annual, seasonal, and monthly climatological distribution fields of phosphate at selected standard depth levels of the world ocean on a one-degree latitude-longitude grid. Most of the historical data were collected over the continental shelf near shallow intertidal areas (< 200 m depth). This map presents the seasonal climatological mean fields of phosphate for two water depths (10 meters and 250 meters) on a one degree grid. Measurements are in umol/l. Seasons are as follows: Fall (October - December), Winter (January - March), Spring (April - June), Summer (July - September).

Silicate - Climatological Mean

Scientifically quality-controlled historical in situ silicate data in the World Ocean Database 2013 obtained by chemical methods were used to construct annual, seasonal, and monthly climatological distribution fields of silicate at selected standard depth levels of the world ocean on a one-degree latitude-longitude grid. Most of the historical data were collected over the continental shelf near shallow intertidal areas (< 200 m depth). This map presents the seasonal climatological mean fields of silicate for two water depths (10 meters and 250 meters) on a one degree grid. Measurements are in umol/l. Seasons are as follows: Fall (October - December), Winter (January - March), Spring (April - June), Summer (July - September).
