"Since ocean waves often pull the surface buoy underwater the air intake that communicates with the barometer is protected with a specially designed self-draining port and waterproofed with two Gore-Tex® membranes.\n",

"When the drifter goes underwater erroneous Sea Level Pressure readings will occur, and these are filtered out by an on-board algorithm before the data message is formatted and queued for satellite transmission. Like the SVP, the lifespan of the SVPB drifter is in excess of two years." ;
