3/3/07 1159Z
3/3/07 1953Z
3/4/07 0159Z  (bad T/RH so used 2nd sonde)
3/4/07 0702Z
3/4/07 1205Z
3/4/07 1509Z  (missed some low level data, but not as much as plot suggests)
3/4/07 1746Z  (no GPS so used 2nd sonde)
3/4/07 2036Z  (missed a few low level points)
3/4/07 2220Z  (shifted freq to 402.4MHz)

We launched the mid-transit sounding between the end of the first transect 
(station 13) and the deployment station for ASIS and the SeaSoar.  This
was the first launch while underway.  Since the ship was heading east, the
wind was mostly from the aft quarter.  I launched the first one as close to
the starboard stern corner as I could, but it went unexpectedly forward and
got chopped off by the crane.  (B4920006) 

For the second attempt, we asked the bridge
to slow to 8 knots, and I launched in front of the starboard crane.  The
wind coming from port across the fantail, and the slower ship speed,
was enough to carry the balloon clear of the crane.

Less interference on this one too.  We got signal all the way to burst, but
there were still some dropouts.

The second sonde we tried could not get a GPS lock.  (B4920388)

Good sounding. We are still fighting the interferance from the bouy transmitters.Hopefully several of those will be turned off today.

Weather conditions: mosdtly cloudy, low cumulus, slight breeze.

Good launch.  Calm winds. Breeze was mostly aft from the boat, so I launched
from the side to get it past the He tanks and other stuff directly behind
the main hangar.  That worked fine.

I bungied the table to two eyebolts on deck, then squeezed the sonde in 
sideways so it was held firm.

Tuned to 404.6 MHz.  Still some interference, especially up high with
the weaker signal.  Slow ascent rate: 2.5-3 m/s.

Signal did not look as wide or strong as I expected in the spectrum 
analyzer, but SNR was about -70.  Saw 7 satellites at launch.

Weather conditions: some sun, mostly cloudy, calm winds.

Good launch.  Calm winds so it lifted straight off the deck aft of the
main hangar.

We believe we've discovered the source of the telemetry interference.  There
are a few buoys around, in particular the ASIS buoy still on the ship,
which transmit in the 400-405 MHz band.  For this launch the sonde was
tuned to 404.5, and one of the drifts was turned off, so there was less
interference but still some dropouts, especially higher in altitude.

Serial number: B4630023

Surface obs from the ship monitor:

RH 62%
Temp 8.42 C
wspd 12.7 m/s
wdir 339 deg
pres 1015 mbar

Weather conditions:  Breezy and dark.  I think we still have mostly cloud cover
because I can only see a few stars.  White caps on the waves.

It was hard to handle the balloon even in the hangar.  We need to find
out how to get the starboard hangar door closed to mitigate the wind.  With
the wind blowing diagonally to the ship, from starboard to port, the 
balloon flew away from the boat at launch and cleared the obstacles on the
fan tail.
