Flanking Subsurface Mooring A

Reference Designator
GP03FLMA
Array Name
Global Station Papa
Description
Flanking Subsurface Moorings are located at global sites and contain instruments fixed at specific depths along the mooring riser. The flotation buoy for subsurface moorings is located below the sea surface. As they have no surface expression, these moorings communicate and send data to shore via an acoustic link to nearby gliders.

Glider 365 deployed at Papa is failing to retrieve very much data from GP03FLMA-00004. The volume of data acquired from the mooring has been consistently low, seldom more than a few thousand bytes per attempt. The glider has recovered more data from GP02HYPM-D00004, so we think the glider modem is functioning properly. The glider is able to range successfully to the mooring from a number of ranges and orientations, however acoustic requests results in very small data files. UPDATE 11/15/2016: Data telemetry from FLMA-D00004 continues to be very poor for unknown reasons. There are multiple failed attempts. The glider modem configuration was inspected and the S4 shift register has been changed from S4=4 to S4=5 and back again with no measurable improvement in performance. The glider is able to range to the mooring multiple times. The error rates in the log file appear to be relatively high but there is no obvious reason for it.
