Coastal eutrophication: Total Phosphorus (TP) (kilograms of phosphorus from algae biomass per sq. km. of river basin area per day) by country
What the numbers show
Coastal eutrophication: Total Phosphorus (TP) (kilograms of phosphorus from algae biomass per sq. km. of river basin area per day) is currently reported for 60 countries. The highest value is 21,149 kg km2 per day in Large Marine Ecosystem: Yellow Sea; the lowest is 7.93 kg km2 per day in Large Marine Ecosystem: Faroe Plateau.
The median across all reporting countries is 908.16 kg km2 per day, and the mean is 2,137 kg km2 per day.
The gap between the highest and lowest reporting country is a factor of about 2,666.
Over the past decade 34 countries rose and 26 fell. The largest increase was in Large Marine Ecosystem: Somali Coastal Current (up 215.7%), and the largest decrease in Large Marine Ecosystem: Beaufort Sea (down 40.1%).
