Splashpools during high and low tides
during high tide would the salinity of splashpools rise? and in low tides would the salinity drop?
i think this makes sense beacuse during high tide sea water would flow into the splashpools causing a rise in salinity, while during low tide this water goes back into the sea..
What do you guys think?

Why would the salinity be any different at all? What are the factors of salinity?
salinity is the amount of salt dissolved per unit of water right?
So during the high tide, the salinity of the tide pool is the same as the ocean, right? During low tide, the tide pool still has the same water in it - but has anything else changed? Would anything have happened that could have changed the salinity of the pool?
Here's an idea: When the tide goes down and the pool is exposed, evaporation can occur in the pool. The salt in the pool has nowhere to go, so it becomes more concentrated as the water evaporates.
On the other hand, if the tidepool has a source of fresh water such as a small stream, or rain, then the salinity will be diluted and the tidepool will in fact have a lower salinity.
I just realized I've been talking about tidepools all this time and you said splashpool. By splashpool do you mean a pool that is never covered by the tide, but only retains water that is splashed into it during high tide? If so, then the salinity of this pool will be much higher than the ocean, because of the constant process of filling and evaporation.

Or maybe take into consideration the location of said pools.
Does temperature have anything to do with the concentration of salt in splash pools?
Extreme hots or cold, or the speed of the currents, depending on how long there is between the last time and the next time the pool would be filled or mixed with new salt water...

Re: Splashpools during high and low tides
A splash pool would be outside the intertidal zone, and only fill with water that is splashed/sprayed into it, or rain.
So as long as it's not being flushed out, the salt water will stay and evaporate leaving higher concentrations of salt every time a tide comes and goes.
