A script was run using Wimsoft software (http://wimsoft.com) to find the best daily coverage of
satellite-detected surface Chl-a in the Scotia Sea and Drake Passage area, estimated by the number of
valid pixels. Missing pixels are due to the combined effect of clouds, ice,
low light and/or missing
orbital coverage of the various satellite sensors.
The coverage
(Count of valid pixels and % Clear) depends, of course, on the
target area
(mask) that was made to cover the Drake Passage. The images themselves are much
bigger and cover all the Scotia Sea and the surrounding areas. The mask
where cloud-free pixels are counted covers the AMLR region and is bounded by
white line (see below, left panel).
