Shiba is made up of the kanji 志波 which seems to mean "wave" and "kindness." Kaien is made up of 海燕 which mean "sea/ocean" and "swallow" (the bird).

You can look up the meanings of individual kanji on Tangorin.com and the kanji can be found in the intro of each character's page. Individual kanji sometimes mean different things when put together with others but that'll give you the the general gist of it.
