Satellite Imagery and Sea Spray

There were very strong northerly winds occurring in southeast Alaska today producing lots of sea spray which visible satellite imagery was able to capture. The Truecolor RGB below shows a lighter grey color over water where there is evidence of sea spray. Greater sea spray indicated greater winds.

The photo below shows what conditions were like at the surface. The thin hazy layer just above the sea surface is the spray.  When temperatures are well below freezing this is a major hazard for mariners as ice accumulates on the ship’s superstructure and makes it unstable.
