Can you repeat Cetus bounties?

Excuse me, could you please clarify something for me regarding the Cetus bounties? I understand that bounties are tasks or missions that players can undertake to earn rewards, but I'm wondering if the Cetus bounties are repeatable? In other words, can I do the same Cetus bounty multiple times to earn more rewards, or are they one-time offers? It would be greatly appreciated if you could shed some light on this matter.
