Global chlorophyll levels,1979-1986. Global satellite map showing average chlorophyll levels in the Earth's oceans during the period from 1979 to 1986. The ocean colours show concentration of chlorophyll (due to phytoplankton blooms) in milligrams per cubic metre,from low levels (dark blue,0.01) through light blue,green,yellow and orange to high levels (red,1). Land is blacked out. The chlorophyll data was obtained by the Coastal Zone Color Scanner (CZCS) radiometer sensor on the Nimbus 7 spacecraft. This sensor operated for 5.5 years from November 1978 to June 1986 | |
