Comparison of night and day photos Rushy Marsh Pond and the ocean

I wanted to understand the effects on the photos I took at night previously of shooting at night / in the snow compared to shooting during the day, so I went back to the same locations today and took pictures of Rushy Marsh Pond and the ocean, with roughly the same scenes.  The color difference is striking; I think it is due in large part to the cloud cover at night.  It would be good to take these night shots again on a clear, moonlit night (the moon is about 3/4 full) to confirm.
