That is indeed a radiosnde. If it has a cellulose-based covering, it
will probably dissolve in seawater within a few hours. If it has
plastic, then it's possibly a recoverable device. The disposables are
worth about $270 each brand new. They have a GPS transmitter as well
in order to measure winds. Once they hit their max height and the
balloon bursts, they will broadcast a terminate signal to the station
monitoring it so the operator and the weather guessers have a mB height
reference point and time in regard to where the measurement stopped.
I was an upper-air specialist in the Navy. I miss that job kind of.
Highest I ever got my balloon was just over 89,000 feet over the
Indian Ocean. I think the record for a US naval vessel at sea was
92kft. The latitude has a lot to do with burst height as it is
significantly "thinner" the farther away from the equator the balloon
is.
Good times.
