Today Don and Joe photographed Sargassum at Station #5 from increasingly higher altitudes, using the red rokkaku kite. The Sargassum windrows are just barely visible in the second photo, but then they are obscured by clouds at the highest altitudes. The device attached to the line in the third-to-last photo is a wind sensor. Expedition log: http://www.schmidtocean.org/story/show/619
