Monthly Average Ocean Phosphate Concentration (CMEMS)

This dataset shows global daily and monthly mean phosphate (PO₄) concentrations in seawater from the surface to 5.1 meters in depth. The data are a product of the Global Ocean and Biogeochemistry Analysis system, a global biogeochemical simulation using the PISCES model [https://www.nemo-ocean.eu/framework/components/engines] and are displayed at a 0.25° by 0.25° resolution.

Nutrients, such as nitrogen and phosphorus, are essential for plant and animal growth and nourishment, but the overabundance of these nutrients can be toxic to aquatic organisms. Phosphorous, in the form of phosphate, is naturally abundant in the environment, but high concentrations in water are usually an indicator of pollution.The main sources of phosphorus pollution [https://www.wri.org/initiatives/eutrophication-and-hypoxia/learn#sources] are agriculture nutrient sources. Phosphorus, which binds to the soil, is generally lost through soil erosion from agricultural lands, but can also originate from chemical fertilizer run-off, manure from cattle farms, and aquaculture operations. Other sources of phosphorus contamination in seawater include fossil fuel combustion and wastewater.

Phosphorus flows from rivers in streams into the ocean, where it disrupts the nutrient balance in marine systems and causes overstimulation of growth of aquatic plants and algae. Excessive growth of these organisms can use up dissolved oxygen as they decompose and block light to deeper waters. This process is known as eutrophication [https://www.wri.org/initiatives/eutrophication-and-hypoxia/learn#impacts]. If enough oxygen is removed the water can become hypoxic, where there is not enough oxygen to sustain life. This removal of oxygen creates an oxygen “dead zone.”

The Copernicus Marine Service [https://marine.copernicus.eu/] is the marine component of the Copernicus Programme of the European Union. It provides free, regular and systematic authoritative information on the state of the ocean, on a global and regional scale. It is funded by the European Commission (EC) and implemented by Mercator-Ocean International [https://www.mercator-ocean.eu/]. It is designed to serve policy and commitments related to Ocean Governance, to cater for the needs of society at large for global ocean knowledge and to boost the Blue Economy across all maritime sectors by providing free-of-charge state-of-the-art ocean data and information.
