Steampunk is a genre, manga is a medium.

Steamboy came out in 2004. And the english dub had Patrick Stewart. A novelization and a manga were both done in parallel.

Sakura Taisen started as a squad tile fighting game game on the Sega Saturn. A manga was done by Tokyopop and the scans are on Mangadex.

Nadia is much older, all the way back in 1990. Loosely based on 10,000 Leagues Under the Sea but it's from Hideaki Anno (Neon Genesis Evangelion) and... Hayao Miyazaki of all people, so all pretense about being based on anything disappears pretty quickly. Where things get really weird is that Evangelion was originally supposed to be a direct sequel to Nadia set like a hundred-some years later in modern day, but the project backers wouldn't okay it in that form.
