When did NASA stop exploring the ocean?

Excuse me, but I couldn't help but notice the mention of NASA and the ocean in your statement. I'm a bit puzzled, as NASA, the National Aeronautics and Space Administration, is primarily known for its space exploration endeavors. So, could you please clarify? Are you referring to a specific collaboration or project between NASA and an oceanographic organization? Or perhaps there's a misconception here that I'm unaware of. I'm genuinely curious to understand the context behind this question.
