Methodology:

Global measurements of ocean chlorophyll concentration were combined from both the SeaWiFS and MODIS-Aqua "ocean color" datasets.

The 0.25-degree spatial resolution data were plotted on a map using a non-linear blue-to-green color bar, with blue being the lowest values and green being the highest values. This global dataset was plotted in a "North America only" subset.. Numbered labels were added indicating sub-regions for which accompanying time series are shown.

Processes

How the source was modified: The original 351 month-by-year full-resolution [satellite chlorophyll] data files were reduced from 9km to 0.25-degree spatial resolution and then averaged into a single all-months-from-all-years "climatology".

The duration of this activity was 4 hours.
