Running the pipe up a building sounds more expensive (in terms of effort:
find someone w/a 12 story building willing to let you do science like this,
and haul in enough seawater) than just getting a boat and going out to
sea.  Also potentially less conclusive.

...yeah.  Do you have the original report, that the reporters can be
contacted and asked how they acquired or made that membrane?
