I am almost certain it is due to using a reflected meter to read a very bright subject. I am especially certain because you used the same meter for both readings, so there are definitely no mis-calibration issues going on. That is just what reflected meters do, and why I generally dislike them so much. I think they do more harm than good for anyone but the rankest of amateurs, who have no idea how to judge light yet.

Out of curiosity, what were the two exposures suggested by the two metering methods?

On a beach in bright light using negative film, I would probably just use sunny 16. Sand is bright. So I want it to have some healthy density on the neg. Using transparency film, I would probably close down half a stop, based on experience. Sand can blow out quite easily on transparency film. In bright snow that was covering the ground, I'd close down a whole stop with transparency film, and use sunny 16 with negative film.
