Such statements undermine funding efforts for large scale oceanographic projects. I am sure Trump would lovet it...

Daniel Vaulot @daniel-vaulot.bsky.social · Aug 8

The following statement is utterly misleading "The cost of this venture pales in comparison to running a scientific research vessel, while yielding far more information..." A bunch of random measurements will never replace a carefully planned cruise with a very large number of metadata.
