On-site personnel:
The AGO team consisted of Kevin Killilea (Field personnel/Groomer) and Tom  Barfield and Joe Kujawski (AGO technical service team).
 

Station:
The station was cold upon arrival.  The AGO lost function due to a blockage on  the air exhaust.  Part of the failure caused ice formation in the exhaust  manifold.

The technical service team successfully started the thermo-electric generator and raised the station temperature to 17-22 C.  That temperature was maintained throughout the service call.

The CAGOSYS upgrade was completed.  Additionally, a 100 lb propane cylinder  located outside the AGO shelter was plumbed for cooking.  The 100 gallon  cylinder that was isolated last year (because it was leaking) was relocated to the auxilary tank position.

AGO-1 was not targeted to be raised this year and will not need to be raised  for several years.
 

TEG:
The TEG was upgraded to add a forced combustion air delivery system, called  the Turbo, and to make it compatible with the new station configuration.   Additional noise suppresion (capacitors and inductors) were added to the  Turbo electronics to reduce EMI to an acceptable level.

Batteries for the electronic shutoff valve were changed.  Manifold propane  pressure was set to 3.5 psi.  The maximum burner temperatures that could  be achieved are:
#1: 210  C, #2: 240   C, #3: 220   C, #4: 230   C, #5: 240   C, #6: 230   C.
 

Data Control Unit (DCU):
CAGODCU Rev. 1 was installed.  Also installed were two Storage computers  (Rev 2, SN: 004 and 019).

The optical disks containing data gathered during the past year were  retreived and will be sent to Augsburg for processing.

Power Supply Controller (PSC):
CAGOPSC Rev. 2 was installed without any problems.

See AGO1.AGO for experiment power settings, priorities, and other station  information.
 

Data Acquisition Unit (DAU):
All functions were normal when the unit was turned on.

Non-volatile random access memory was replaced.

The DAU was upgraded per CAGODAUM Rev 0.  See AGO1.AGO for DAU settings.
 

Global Positioning System Receiver (GPS):
The GPS was functional when the AGO electronics were turned on.
 

Bell Labs Fluxgate Magnetometer:
Data was examined to verify the operation and leveling of the magnetometer.  By examining this data, the service team determined that there was no need to  change the magnetometer settings.

Settings for the magnetometer are:

Sensitivity : 1000 nT
H Offset   :      +    00 07 220
D Offset   :    OFF 00 00 000
Z Offset    :     -      02 08 940

The electronics were checked out per the servicing documentation.  The results of the checkout were as follows:

Axis    Meter Out        DAU       Save File
         Reading       Reading        Name
 H:     -10.000 V       015 H     P199_FLH.GIF

 Z:     -10.000 V       00C H     P199_FLZ.GIF
        +10.000 V*      FFA H                    * Scale adjusted to 10^3

The secondary ground on the experiment was connected to chassis.
 

Tohuku ULF Search Coil:
Tohuku was upgraded per CAGOULFM.  Sample data was recorded to disk.
 

Stanford VLF Receiver:
The Stanford experiment was not calibrated since the calibrator went to AGO-3.   Data was collected and examined for possible problems.

Settings for the experiment are as follows:
8-16 KHz         20
16-32 KHz       20
0.5 - 1KHz      20
4-8 KHz           20
24.0 KHz NAA    RF-20   IF-15
1-2 KHz NS      10
2-4 KHz           10
30-40 KHz       10
1-2 KHz EW     10
Line Receiver NS        30
Line Receiver EW        35
 

University of Maryland Riometer:
The signal attenuators provided by the University of Maryland were installed.   After installation, data was observed and found to be very noisy in both  channels.  The service team could do nothing to improve the noise and left the  attenuators in place.  See P199_RI1.GIF and P199_RI2.GIFfor collected data.
 

Anubis Seismic:
Both seismometers were tested and one was found to be non-functional.  The  working seismometer was installed in a vault upwind of the station.  After the
vault was dug and the seismometer was installed it was discovered that both of the Reftek units were non-functional.  The service team tried to make a  functional unit from the non-functional ones by trading PC boards between the  units.  Unltimately, the RefTek could not be made to work.

The vault electronics were left at the site and both RefTeks were retro'ed.   Power to the experiment was turned OFF.
 

Dartmouth LF/HF Receiver:
Data was collected and examined on the Dartmouth experiment.  Sample data can be seen in P199_LFH.GIF.
 

Allsky Camera:
The battery was replaced.  The allsky camera was upgraded to CAGOALLM Rev. 1. The calibration flashlight was used to collect sample data.  One image is  present in P199_ALL.GIF  Due to the late arrival of the calibration flashlight, the  service team did not find out that the batteries for the instrument were not  included until AFTER the team arrived at the AGO.  The team had to use two very old 'D' cell batteries found at the site and two new batteries which had been brought for other purposes.
 

NASA LIDAR:
The service team had planned to remove the Lidar from the site this year.   However, neither the shipping containers nor the instructions for removal had made it to McMurdo in time for the service visit.  As a result, the insturment was disconnected and kept at the AGO site.
 

Miscellaneous:
GPS position:  S 83  52'  E 129 37'. Elevation: 2813 m.

Notes for the future:

1) Experimenters that provide cable for outside use should provide cables that are cold-friendly and are flexible at -40 C.
2) Experiments that provide junction boxes and connection points outside the AGO should allow for the fact that these connections will be made by people
   with gloves and should have adequate spacing between the connectors.
