Does sand from the Sahara really cross the Atlantic Ocean?

    Yes! The North Atlantic receives sand/dust particles from the Sahara and there are actually marine organisms that depend on it. Globally, about 1,700 million tonnes of dust are produced annually by deserts and about one third of this falls into the oceans.

    It would be extraordinary for actual sand grains to blow all the way across the Atlantic. The article cited in the other answer does not seem to distinguish between dust and sand, but sand grains are, at smallest, one-sixteenth of a millimeter across. That may seem small but it is quite a challenge for wind to move such a grain very far. Not saying it never happens, but most of the material that makes it across the Atlantic will be far, far smaller than that.
