Method 2
Under the previously explained assumption that 6% of
the total primary production in NPSG euphotic zone occurs
in the first 5 meters of the water column, the part of
the primary production that comes into contact with the
Array equals the daily water flow times the net primary
production in the top 5 meters:
Primary production of 219 mg C / m2 / day equals 219*106
mg C / km2 / day.
Therefore, the daily primary production of water flowing
through The Ocean Cleanup Array equals:
Minimum: 1210 km² / day * 219*106 mg C / km² / day * 6%
= 15.9*109 mg C, or 15.9*103 kg carbon daily
Maximum: 1210 km² / day * 1055*106 mg C / km² / day *
6% = 76.6*109 mg C, or 76.6*103 kg carbon daily
Therefore annually, a body of water with a net primary
production between 58.0*105 and 280*105 kg carbon
flows through The Ocean Cleanup Array.
