  Attepted a dark cast. Unable to start the FRRF! Aborted the cast.
  
  Checking the FRRF indicated that all stored protocols were erased
  when it was sent back for calibration. Using the following boot

Note:

  The TSRB was not able to be recovered. Below is an excerpt from Tom
  Gregory's Chief Scientist Cruise Report:

  > We recovered the gas array at around 0200 this morning with all N2
  > samples intact.  The TSRB had been deployed with this array.
  > Regrettably, the TSRB was no longer connected to the gas array when
  > recovered.  It must have broken free at some unknown time during the
  > deployment; the cause appears to have been hardware failure.  We spent
  > several hours early this morning (while still dark) searching for
  > visual recognition of the strobe and/or the RDF signal but failed to
  > locate the instrument.  The gas array drifted 10 nmi. in 24 hours.  The
  > TSRB, once free of the array, would have rapidly drifted away from the
  > array.
