worked at a e-science project himself. He told me people, especially
is this "e-science" term more popular where you are? I don't really
hear it here (Canada, probably NA in general.) many (most) branches
of science are so dependent on computers that it seems redundant and archaic.
scientists are "very jealous" of their data. And not replying is a
kind way of saying "no". And there's the problem of "who's this guy
wanting my data", "what will he do with it?".
sure - academia is all about publishing, so you don't want someone
else to scoop you.
This is an interesting aspect. All the latest Announcements of
Opportunity for space research (think cameras taking pictures of
Mars, or analyzing rocks etc.) have fairly fast time lines(weeks, not
months or years) for relase of data to general public, and you have
to put your plans and budgets for public distribution in the
proposal. No more holding onto the data, "recalibrating and
reprocessing", until everyone gets their dissertations done.
The Dead Sea Scrolls are probably a pretty notorious example of
"we're still working on it.. when we're done, we'll release
it"...Amazing what a computer and a concordance can do.
but often concerns are much more mundane, like:
- how long will it transfer this 50GB blob of data?
Think terabytes, for many data sets. QuikSCAT gives you wind vectors
for 90% of the world's ice free ocean twice a day on a 25 km
grid. Raw radar data coming down from the spacecraft before
calibration is basically 200 odd measurements/second (each
measurement consisting of 10 numbers) continuously 24/7. And, that's
a low volume sensor. Something like a SAR doing radar imaging is
orders of magnitude greater. Sipping from a firehose indeed.
- if I provide neurophysiology data from my lab, can I
be sued if the subjects' privacy is violated?
- do I have time to spend explaining how the data is encoded?
That's a biggie... Budgets are always limited, so they tend to do
just what's needed for the immediate purpose.
