s1: didn't record – approximately 11:00
P.S. From the data, call the times:
s15: 0959-1003
s9: 1028-1033
s1: 1047-1053
P.S. The wetness sensor at s15 was completely out of the water (though the tide was coming up), though it had a few weeds adjacent to it and clearly had some mud splatters on it. I pulled most of the weeds, but left the mud (arguing that it would just get muddy again soon)
