Kalliroi

Kalliroi is a modern Greek form of the Classical name Callirrhoe, who in mythology was an ocean nymph who accompanied Persephone to the underworld. If you're looking for unusual names with ocean meanings, this should be on your list.

Kalliroi Parren was responsible for (almost single-handedly) launching the Greek feminist movement when she founded the Women’s Journal in 1887. She advocated strongly for educational and employment equality.
