A luminous sea from two crew cameras
Compare the Ganesha crew’s photographs from an Indonesian milky-sea encounter with the investigation that linked their voyage to a satellite-detected glow.
What to keep in mind
The published figure combines two actual exposures and processing. Panel B is a colour adjustment based on recollection, not a third photograph or a measured colour spectrum.
Compare the two exposures
In panel A, use the boat and horizon to locate the luminous water in each camera view. What appears in both despite their different responses?
Separate processing from observation
Compare the Samsung image in panel A with panel B. Which change represents the crew’s recollection, rather than another camera observation?
What connects sea and satellite?
Write down the time and route information needed to associate these photographs with a satellite glow. Why is a similar-looking bright patch insufficient on its own?
