Observations
Airshipped from Boston / Paris / Nantes and then
truck Nantes to Brest. Nantes is the closest airport
with cargo facilities. Due to the box sizes, it can only
go in a cargo. Open the box and visually inspect the
glider and the box content. Nothing to note.

First try to pdeploy the glider but cancelled
due to bad weather
Deploy the glider but unsuccesfull. Decide
to get it back to Brest for pressure tank
tests.
Verification of pool water characterisitics showed a
significance diffrence with the previously assumed
numbers.
Deepy alone was deployed

During the first try of the mission at 30 m, the glider
never came back to the surface due to a bad
functionning of the vehicle pressure sensor. Vaseline
was introduced in the capillar for corrosion problem
but it prevents the pressure to be correctly transmitted
to the sensor. Back to shore with the glider.

glider and put a vacuum at 7.4 inHg
Check the vacuum is not decreasing .
record Vacuum and internal temperature.
Open the glider again to prepare the
pressure tests by setting a cable for
communication thru the pressure tank

Vaseline clearly seen at the entrance of the pressure
sensor. Check pressure variation with vacuum pump
and nitrogen injection (adtest)
Same vacuum pump and nitrogen use
Vehicle pressure sensor OK
Pump ran OK in presure tank
Pool tests showed offset between vehicle pressure
sensor and SBE CTD pressure sensor
Pump was set OUT OF SERVICE due to an OUT
OF DEADBAND error (later corrected by soft)

2 wires on connector 5 points i.e. cable for the optode
are broken. No tool to redo the connector
soldier
the wires ?!
No problem except a false alarm with the altimeter.
1 CTD with 5 samples at 5 depths
Dives to 300, 500, 800 and 1000 m.
Problems encountered
- 04/02 abort device_error due to optode ; turn it
off
- 16/02 abort same_depth : landing on the bottom
during the slope approach off Barcelona
- 27/02 abort device_error : link to the pump but
happens once and did nothing
- 04/03 abort device_error : link to the pump send
a command to reset a flag on Potame
!put x_de_avg_oil_vol_err_on_descent 0
- 05-06-07/03 abort no_tickle : Potame suddenly
too light cant dive; very bad waetaher, not able
to connect for 4 days
- 08/04 abort overdepth : still not able to dive
change the pump volume to fix the case
