Asked by Lars
A salinity meter placed in a tidal pool shows a dramatic decrease in salinity between 2 A.M. and 3 A.M.. This decrease is followed by a gradual rise in salinity from 11 A.M. until 4 P.M. the next day. What might explain these changes?

it rained?
This decrease is followed by a gradual rise in salinity from 11 A.M. until 4 P.M. the next day.
evaporation? Although if it is low tide between 2 am and 3 am then sometime in the next 11 hours the tide will come in and replace the water in the pool, which will also cause the salinity to rise.
